Robocopy provides features not found in the built-in Windows [[copy (command)|COPY]] and [[XCOPY]] commands, including the following:
* Recovering from temporary loss of network connectivity (Incomplete files are marked with a date stamp of 1970-01-01 and contain a recovery record so Robocopy knows where to continue from).
* Detecting and skipping [[NTFS junction point]]s, which, under certain circumstances, may cause copying failures because of infinite loops (with the <code>/XJ</code> switch).
* Preserving any combination of the following: file contents, attributes, metadata (e.g., original timestamps), NTFS [[Access Control List|ACL]]s (DACLs, SACLs, and owner). For example, it is possible to copy ACLs from one file to another. Before version XP026, however, this capability was limited to files only, not folders
* Utilizing the [[Windows NT]] "Backup Files and Directories" privilege (<code>SeBackupPrivilege</code>, normally not available to standard user accounts) to bypass NTFS ACLs that would otherwise impede transfer (requires the <code>/B</code> switch).<ref>{{cite web | url = http://theether.net/download/Microsoft/Utilities/robocopy.pdf | title = Robocopy.exe - Robust File Copy Utility - Version XP010 | publisher = [[Microsoft]] | year = 2003 | quote = Backup mode copies [...] enable you to copy some files as a Backup Operator that you would not be able to copy as a normal user. }}

* Persistence by default, with a programmable number of automatic retries if a file cannot be copied.
* The mirror mode, which keeps two directory trees synchronized by also deleting files in the destination that are not present in the source.

* Support for paths exceeding 259 characters, up to a theoretical limit of about 32,000 characters.<ref>{{cite web|url=http://www.windowsitpro.com/content1/topic/robocopy-xp010-faq/catpath/migration/page/2|title=Robocopy XP010 FAQ|last=Lewis|first=Dick|date=15 November 2004|website=Windows IT Pro|publisher=Penton Media|page=2|archive-url=https://web.archive.org/web/20121009110523/http://www.windowsitpro.com/content1/topic/robocopy-xp010-faq/catpath/migration/page/2|archive-date=9 October 2012|url-status=dead}}</ref>

Although Robocopy itself is a command-line tool, [[Microsoft TechNet]] provided a [[GUI]] front-end called Robocopy GUI. It was developed by Derk Benisch, a systems engineer with the [[MSN Search]] group at Microsoft, and required [[.NET Framework]] 2.0.<ref>{{cite news |author=Joshua Hoffman|title=Utility Spotlight Robocopy GUI|url=https://technet.microsoft.com/en-us/magazine/cc160891.aspx|work=TechNet Magazine|publisher=Microsoft Corporation and CMP Media, LLC|date= November 2006|access-date=2008-07-17 }}</ref> It included a copy of Robocopy version XP026.

There are non-Microsoft GUIs for Robocopy:
Ken Tamaru of Microsoft developed a copying program with functionality similar to Robocopy, called [[RichCopy]], discontinued in 2010.
