Does xcopy replace existing files?

Copies source files changed on or after the specified date only. If you do not include a MM-DD-YYYY value, xcopy copies all Source files that are newer than existing Destination files. This command-line option allows you to update files that have changed.


Add /Y to the command line


You can use :

copy /b/v/y

See SS64 on COPY.


Add /y to the command line of xcopy:

Example:

xcopy /y c:\mmyinbox\test.doc C:\myoutbox

you need to simply add /Y

xcopy /s c:\mmyinbox\test.doc C:\myoutbox /Y

and if you're using path with spaces, try this

xcopy /s "c:\mmyinbox\test.doc" "C:\myoutbox" /Y

If the copy command is run from within a batch job you do not need to use the /Y switch: it will overwrite existing files.


For copying one file to another directory overwriting without any prompt i ended up using the simply COPY command:

copy /Y ".\mySourceFile.txt" "..\target\myDestinationFile.txt"

A command that would copy in any case

xcopy "path\source" "path\destination" /s/h/e/k/f/c/y
