Hi Andi – you found a bug, which is now fixed in the 2013.3.21.20.10 build I just published a few minutes ago.
However, even though there was a bug in the software, you might still consider an alternate way of accomplishing what you’re trying to do.
In the way you’ve described doing this, you would end up copying the file from a network file share, down through your computer running BatchPatch, and then up to the target computer location. This will work fine, but for large files it might not be ideal to have your computer act as a middle-man for the file transfer, especially if you’re trying to do this for many target computers at once.
Instead you might consider using the “Remote Script/Process” with a command like this:
xcopy \someNetworkSharefolderfile.txt c:folderOnTargetComputer
This will execute the xcopy command on the target computer instead of the local computer running BatchPatch. So, the target computer will then directly reach out to the network share and copy the file back to itself, without the file ever having to be pulled through the computer running BatchPatch.
Hope this helps.
