How can I write this very specific batch file

[anthonyaudi]

So would a simple Robocopy c:\test c:\test /copyall simply copy over whatever is in the directories of the source to the destination without overwriting anything in the destination other than what is in the source?

(I don't know if that made sense in writing)

source = c:\test\.abc\pdf file

destination = c:\test\abc\pdf file (and other non corrupted files)

that robocopy command would simply place the c:\test\abc\pdf file in the destination without otherwiriting whatever else is in c:\test\abc

correct?

Overwrite and delete are completely different.

At this present time I'm not sure of your exact requirements and goal. As you must understand we need to be 100% sure of your intentions before providing irreversible and potentially catastrophic solutions for you.
