Robocopy is a command-line file transfer utility for Windows. It is functionally more comprehensive than the COPY and XCOPY commands, but replaces neither. Created by Kevin Allen and first released as part of the Windows NT 4.0 Resource Kit, it has been a standard feature of Windows since Windows Vista and Windows Server 2008.

==Features== Robocopy provides features not in the and commands, including: 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 points, which, under certain circumstances, may cause copying failures because of infinite loops (with the /XJ switch) Preserving any combination of the following: file contents, attributes, metadata (e.g. original timestamps), and NTFS ACLs (DACLs, SACLs, and owner) For example, copying ACLs from one file to another; before version XP026, this capability was limited to files only, not folders Utilizing the Windows NT "Backup Files and Directories" privilege (SeBackupPrivilege, normally not available to standard user accounts) to bypass NTFS ACLs that would otherwise impede transfer (requires the /B switch) 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 Skipping files already in the destination folder with identical size and timestamp Progress indicator Support for paths exceeding 259 characters, up to a theoretical limit of about 32,000 characters Result code indicating success or failure; used in automation Multithreaded copying (introduced with Windows 7 and Windows Server 2008 R2) Support for server message block (SMB) compression (introduced with Windows 10 and Windows Server 2019) If /compress is specified, the destination computer supports SMB compression, and the files being copied are compressible, the operation enjoys significant performance improvements
