[[Special:UploadWizard|جادوگربارگذاری]] اجازهٔ رونویسی پرونده‌ها را نمی‌دهد.</ref> راهنمایی در این باره ضروری می‌نماید چون هم پروژه‌های ویکی‌مدیا که بر پرونده‌های ویکی‌انبار متکی هستند و هم [[Commons:Reusing content outside Wikimedia/technical|استفاده‌کنندگان خارجی که مستقیماً از محتوای ویکی‌انبار استفاده می‌کنند]] انتظار دارند که پرونده‌ها به طرز معقولی پایدار باشند. در نتیجه، قاعدهٔ پایه‌ای چنین است که  '''پرونده‌های موجود نباید با محتوای اساساً متفاوت رونویسی شوند، اما بهبودهای جزئی باید بر نسخهٔ قبلی رونویسی شوند''' (برای آگاهی از استثناها ''پایین را ببینید''). وقتی شک دارید یا به هنگام رفع اختلاف بین کاربران، نسخه را تحت نام جدید بارگذاری کنید.

After [[Commons:Village pump/Archive/2012/08#Commons%3AOverwriting existing files|discussion in August 2012]], this guideline was [[Commons talk:Overwriting existing files/Archive 1#RFC|proposed and formally adopted as an RFC]]. As of September 2023, a further discussion concluded that many overwrites did not comply with this guideline, so [[Commons:Village_pump/Proposals/Archive/2023/08#Limit file overwriting to users_with_autopatrol_rights|it was decided that it should be strictly enforced in software]] by limiting overwrite privileges of images uploaded by other users to those with the [[Special:MyLanguage/COM:AP|autopatrol]] right. If you want to overwrite files initially uploaded by other users, please request the autopatrol right on [[COM:Requests for rights]]. If you are not eligible for this right, you may [[Commons:Overwriting existing files/requests|request an exception]] for a specific file.

{{tick}} As a general rule, use the link "Upload a new version of this file" only for relatively minor improvements. Examples include:
</div>
* <span lang="en" dir="ltr" class="mw-content-ltr">replacement with higher-resolution versions of the same file, however, without using artificial methods to generate higher resolution</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">minor and uncontroversial color correction, noise reduction, perspective correction, etc.</span>

<div lang="en" dir="ltr" class="mw-content-ltr">
and similar things where the essential composition is not altered. This might include a minor crop, for example to remove a recently-added border (don't upload over with files that remove parts of historical images), but aggressive crops should usually be uploaded under a new name, such as "Old image name (crop).jpg".
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Correction of minor errors will usually be considered a minor improvement. However, the more extensive the correction, the more likely that it is better to upload the corrected version as a new file (to avoid possible disagreements about whether the correction is appropriate, and potentially an [[#COM:UPLOADWAR|upload war]]), and if necessary nominate the old file for deletion.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Note: a file with {{pg|Commons:Image annotations|image annotations}} will lose those annotations if the pixel dimensions change – ''see {{pg|Help:Image-Annotator#Limitations}}''. This is not a reason to split a file when making minor improvements, as the annotations can be re-entered.
</div>

==== Exceptions ====
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{notok}} If '''digital restoration''' work is being done on a historical document or artwork, the restoration (no matter how minor) should always be uploaded under a new filename from the original file, providing a link back to the source on which it was based in the new file's "other versions" field.  The changes that were made should also be documented in sufficient detail to reproduce them, if possible. This is best practice for restorations, because it allows users and subsequent restorers to follow the chain of improvements and to make detailed comparison with the originals. (However, if a restoration already performed to a file, for example, missed a dust spot, it is not necessary to have a new file for each small change in the restoration.) In some cases such original files are marked with {{tl|Please-do-not-overwrite-original-files}}.
</div>
[[File:Cscr-featured.svg|right|thumb|100px|<span lang="en" dir="ltr" class="mw-content-ltr">The symbol for Featured Pictures</span>]]
<div lang="en" dir="ltr" class="mw-content-ltr">
<big>'''?'''</big> Take care with files that have been awarded a '''special status''' like {{pg|Commons:Featured pictures|Featured Picture}} (or the equivalent on another Wikimedia project) as the status applies to a particular file version. Featured Pictures, {{pg|Commons:Quality images|Quality Images}} and {{pg|Commons:Valued images|Valued Images}} will be identified on their file description pages using {{tl|Assessments}}. ({{abbr|NB|Nota bene}} the special Commons status does not transfer to derivative files.) The image creator may make minor changes where they feel this would be uncontroversial wrt the promotional status (for example, removing dust spots or fixing a minor tilt). Potentially controversial changes should be discussed with members of the forum that promoted the image.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{notok}} Files '''used in Wikimedia projects where the use requires the file to remain unchanged''' – which means no overwriting at all: not for updates, minor improvements, or error corrections. Comments (including pointing out errors, and pointing to other versions) may freely be made in the Commons file description, but the file itself should not be overwritten. If necessary, upload a new version as a separate file. Such files should be marked with {{tl|Please-do-not-overwrite-permanent-version}}.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{notok}} '''Controversial or contested changes'''. If another editor thinks that the change is not an improvement (even if the editor making the change deems it minor), the change can be reverted, and the new image should be uploaded under a new file name. ''[[#COM:UPLOADWAR|See below]].''
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Respect content creators ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The original image creator is often the best person to make edits. Since JPG is a lossy format, every edit to a JPG can deteriorate the image slightly; seemingly minor and "beneficial" edits such as changing white balance or adding noise reduction can actually do significant damage. Often the image creator has access to the RAW files from which to make a new version with whatever fix is required. This is always superior to editing the JPG. If it is a photograph, the image creator was there when the picture was taken so will be in a better position to judge whether colours and lighting are correct. Therefore it is strongly recommended that users wishing to make improvements to photographs first contact the creator, whether on Commons or elsewhere.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Unedited versions ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{tick}} Sometimes users uploading new files that have been edited (e.g. a photograph improved for colour, contrast, etc., compared to the raw photo) may wish to provide the original unedited version as well. Uploading these independently would needlessly clutter categories. The solution is to first upload the unedited version, and then shortly afterward to upload the edited version over it, so that the unedited version is available in the file history. The unedited versions are not intended to be used independently, and should not be split out as separate files unless this is needed for a specific known use. Files using this approach should be labelled with {{tl|Unedited version}}.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Note: overwriting unedited versions applies only shortly after upload of the unedited version, and only to the original uploader when uploading an improved version of the same file. In all other cases, the usual criteria about overwriting (''is it minor improvement?'', etc.) apply. In addition, the usual rule about resolving disagreements applies: if another user feels it useful to split the file, it should be split.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Secondary images ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{tick}} Sometimes users may wish to provide an image related to their upload, which might fall outside the {{pg|Commons:Project scope|project scope}} as an independent file. Examples include images of labels related to the subject of the main image, or the reverse of a postcard as evidence of copyright status. The solution is to first upload the secondary image, and then shortly afterward to upload the main image over it, so that the secondary image is available in the file history. The secondary images are not intended to be used independently, and should not be split out as separate files unless this is needed for a specific known use. Files using this approach should be labelled with {{tl|secondary image}}. Note that secondary images are ''not'' exempt from the usual requirements of {{pg|Commons:Licensing|Commons:Licensing}}.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Files with current data ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{notok}} Be cautious about overwriting files with new versions reflecting new information, as in many cases this may not be what reusers want.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{tick}} However, files may be identified to reusers as ones where information may be updated – these files can and should be overwritten to reflect new information as necessary. Identification may be by the [[COM:FN|filename]], file description, [[COM:CAT|categories]], or (most clearly) with the {{tl|current}} template. A file named "[[:File:Germany location map.svg]]" is expected to indicate the current boundaries, and is expected to be updated if, for example, the boundaries changed or errors were observed. On the other hand a file named "[[:File:Germany, Federal Republic of location map October 1949 - November 1950.svg]]" is expected to be correct for that period and not reflect current boundaries.

{{anchor|COM:UPLOADWAR}}
<div lang="en" dir="ltr" class="mw-content-ltr">
=== Controversial or contested changes ===
</div>
{{shortcut2|COM:UPLOADWAR}}
<div lang="en" dir="ltr" class="mw-content-ltr">
{{notok}} Changes to a file that are likely to be contested should be uploaded to a separate filename. Upload wars (a form of {{pg|Commons:Edit war|edit war}} in which contributors repeatedly upload different versions of a file in an effort to have their version be the visible one) are always undesirable. As with other forms of edit warring, users who engage in upload wars may be {{pg|Commons:Blocking policy|blocked from editing}}.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If another editor thinks that a change is not an improvement (even if the editor making the change thinks it's minor), the change can be reverted. Once a change has been reverted, the new image should be uploaded under a new filename (unless the reverting editor explicitly or implicitly agrees to the contested change). This is true even if the change is necessary, in one editor's view, to avoid a copyright infringement: in this case, if agreement cannot be reached through discussion, the old file should be nominated for deletion.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The more known uses of a file there are (through transclusions on Wikimedia projects), the more cautious contributors should be in deciding whether a change qualifies as "minor". Widespread usage of a file makes it more likely that even small changes will be controversial. If in doubt, uploading as a separate file avoids potential surprises for reusers. In some cases, prior discussion with previous uploader(s) or in locations where the file is in use may help decide whether a planned change can be considered "minor".
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Changes that break consistency with other images ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{notok}} When images are consistent among each other, individual images should not be changed in a way that makes them inconsistent with the others. (E.g., [[:File:Icosahedron flat.svg]] should not have been overwritten with a white version, because that broke the consistency of [[:Category:Set of Platonic solids; nets yellow orange|the set]].)
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{tick}} Small changes can be made to all images, as long as they remain consistent. (E.g., it was fine to remove circles around numbers in [[:File:Hawaiian Eruption-numbers.svg]], because it was done to all images in [[Valued image set: Types of volcanic eruptions|the set]].)

<div lang="en" dir="ltr" class="mw-content-ltr">
Minor improvements for textual elements include correcting spelling on a map's labels. By contrast, translating a map's labels from English to German is a major change, and should be uploaded as a separate file.

Whether a crop is "substantial" depends partly on the proportion of the image cropped, and partly on how much the excluded content affects the composition. For an image of a museum object on a grey background, cropping much closer to the object was considered a minor crop:

Though the intent was to restore the image to a better quality version, the overwrite proved highly controversial as it changed the context from a modest pose to a nude with potential erotic connotations. In some existing transclusions this change was unwanted and caused controversy. Uploading the higher quality image as a separate file would have avoided this.

* <span lang="en" dir="ltr" class="mw-content-ltr">Label the image page with the {{tl|current}} template (''see [[#CURRENT|§ Files with current data]]''). The main disadvantage is that the old version cannot be directly linked if needed.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">Create a file redirect page under a fictive filename on Commons and use a link to this filename on the other projects. Change the redirect to each new version (inbound links from other projects need not to be updated). This means updating just one link instead of many. (Note the effect of overwriting or switching over can be delayed slightly through cache delay or can fail through software imperfection.) Example: link to [[:File:Africa borders redirect]] on Wikipedia, and on Commons have [[:File:Africa borders redirect]] point to [[:File:Africa borders 2011]], [[:File:Africa borders 2012]], etc. as-needed.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">Combine the two methods. Particular version can be uploaded (and linked) separately under their specific permanent filenames and a different filename can be marked with {{tl|current}} version and overwritten ever by the current version. That means (just as the previous solution) that the current version is available under two filenames: one for the constant content and one for the updatable content. This solution should be less vulnerable to cache delay and software-update bugs than the previous one.</span>
<div lang="en" dir="ltr" class="mw-content-ltr">
Warning: when doing one of these solutions, be sure that users of the filename are clear that the content of the file may change, and try to check uses of the file before updating the redirect or overwriting the file.

* <span lang="en" dir="ltr" class="mw-content-ltr">'''Ask a user not to overwrite files''': To request that another editor not overwrite an existing file, you may place {{tl|Dont overwrite}} on the user's talk page. This request is automatically translated into many languages.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">'''Label a file not to be overwritten''': {{tl|Please-do-not-overwrite-original-files}} may be used on file pages to designate files that should not be overwritten.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">'''Request a file split''': You can request a split up of file history by adding {{tl|Split}} on the file page. This places the file in [[:Category:Media requiring a split up]]. See also {{pg|Commons:History merging and splitting}}.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">'''[[:Category:Image formatting templates|Image formatting templates]]''' may save having to create a new file version. For example, temporary or illustrative crops may be created using '''{{tl|Preview Crop}}''' rather than creating a new derived image or overwriting an existing image. Images may be overlaid without having to create new derivatives by using the '''{{tl|Superimpose}}''' template.</span>
