How to keep 2 files with same name?

[guialmeida]

Hello

I have 2 foldes in my repository, one of them is to receive all the files that are uploaded or digitalized, and the other one is a synchronized folder that is kind of an backup. I ussually move the files from the folder 1 (that receive the files) to the folder 2 (Synchronized folder), but sometimes i can't move the file 'cause already exist a file with the same name that i'm trying to move.
I would like to know if there's anyway that I can just move the files and duplicate them as we can do on Windows Explorer, adding "(2)" to the file name.

And no, i can't just rename the files, 'cause i'm moving 50+ files all at once, so i can't rename all of them.

You can trigger a rule on that folder.
execute a script and check if the file is already exists with the same name if yes rename it.

First of all, thanks for your attention,

What exactly is "trigger a rule on a folder" and how can I do that? And as I said, I can't just rename the files one by one...
