windows - can't exclude path with a space (xcopy)

I'm trying to use xcopy /exclude:exclude.txt and one of the paths in exclude.txt has a space in it and it's not working. Is there any workaround for this?

Answer

Reading through the relevant sections of the xcopy help

/EXCLUDE:file1[+file2][+file3]...
         Specifies a list of files containing strings.  Each string
         should be in a separate line in the files.  When any of the
         strings match any part of the absolute path of the file to be
         copied, that file will be excluded from being copied.  For
         example, specifying a string like \obj\ or .obj will exclude
         all files underneath the directory obj or all files with the
         .obj extension respectively.

We can see that the exclude option is not working on paths or file names but "filters". To illustrate this I'll try to give a short example. Picture this exclude.txt

Unicorns
Dolphins

This will filter out any file that has unicorns or dolphins anywhere in its name. e.g Dolphins.txt will be filtered but Ponys.txt will be fine.

To get back to your issue. The reason that your filter isn't matching isn't because of the space in the path. By default xcopy will only care about the filename and not the full path, any filter you have that includes a full path will not match and the file will get copied.

You can change this behavior of xcopy by supplying the /f flag in your command. This should solve the issue you're seeing.
