Package - EnableDelayedExpansion, exclamation mark and file / folder names

Question

I struggle with exclamation marks ( ! ) By file and folder names. The batch I created reads the contents of the .txt file and sorts the listed files from a folder into a subfolder.
For example:
source.txtit has inside: file_1.zipand file_2.zip
folder name systemis file_1.zip, file_2.zip, file_3.zipetc. and the package reads source.txtand copies both files to system/source.

I tried to avoid enabling DelayedExpansion, but after adding the folder browser I could not find a better way than using it. I needed it to be turned on for the way I show : listSources and : listFolders My problem right now is not so much processing (!) The folder names (although it would be great to resolve it), but to allow copying files from ( !) in his name.

I was thinking about running away ^^! nature or switching between setlocal and endlocal, but I'm still learning how to use it correctly, so I don’t know how to deal with it. Maybe there is a better way? (I'm not a programmer!)
