![]() The files named are copied only from the folder selected for copying fully qualified path names are not supported.ĬAUTION: A long-standing issue with Robocopy means that if you back up from the root folder of a drive, the destination files will be given attributes including SH. Robocopy c:\bar c:\baz file1.txt file2.dbĪnd to copy all PDF files from c:\bar to c:\baz: įor example, to copy two files from folder c:\bar to c:\baz, the following syntax is used: File names and wildcard characters (such as * and ?) are not valid as source or destination arguments files may be selected or excluded using the optional "file" filtering argument (which supports wildcards) along with various other options. Robocopy syntax is markedly different from its predecessors ( copy and xcopy), in that it accepts only folder names, without trailing backslash, as its source and destination arguments. Mirror A to B, destroying any files in B that are not present in A ( /MIR), copy files in resume mode ( /Z) in case network connection is lost:įor the full reference, see the Microsoft TechNet Robocopy page.Robocopy C:\A C:\B /COPYALL /E /R:0 /DCOPY:T Copy directory recursively ( /E), copy all file information ( /COPYALL, equivalent to /COPY:DATSOU, D=Data, A=Attributes, T=Timestamps, S=Security= NTFS ACLs, O=Owner info, U=Auditing info), do not retry locked files ( /R:0) (the number of retries on failed copies default value is 1 million), preserve original directories' Timestamps ( /DCOPY:T - requires version XP026 or later):.If directory names have non-standard characters, such as spaces, they must be enclosed in double quotes, as is usual in the command line. Robocopy "C:\Directory A" "C:\Directory B" /E Copy directory contents of the source Directory A to the destination Directory B (including file data, attributes and timestamps), recursively with empty directories ( /E):.If more than one option is specified, they must be separated by spaces. Here are some examples of usage, which is not case-sensitive. Compression is also available with the xcopy command and Hyper-V Live Migration with SMB. ![]() The SMB compression adds inline whitespace compression to file transfers. With this switch, if the destination computer supports SMB compression and the files being copied are very compressible, there may be significant improvements to performance. Since Windows Server 2019 and Windows 10, a compression option is available in robocopy when copying across a network.
