Here is how you can copy a single file in SQL Server.

EXEC master.sys.xp_copy_file
'D:\data\test.txt', -- source
'D:\data\newfile.txt' -- destination

The above command needs an exact file name and does not support any wildcards.

If you want to copy multiple files, you can also use the wildcard and the command for the same is a bit different. There is an additional ‘s‘ at the end of the command.

EXEC master.sys.xp_copy_files 
'D:\data\', -- source
'D:\newdata\' -- destination

If the above command, you can also use wildcards if you want. You can also specify file names like a*.txt or *.docx etc.

If you want to delete the files you can also use the command for deleting the files

EXEC master.sys.xp_delete_file
'D:\data\*.txt'

Additionally, note that you can use wildcards to delete the files hence be very very careful with the commands listed above.

The commands which are displayed in this blog post will only work in the SQL Server 2019 and will not work in the previous versions, hence request you to not post a comment that it will not work for the previous version of SQL Server.
