Save files from several sources into ONE folder

Hello all,

I have several computers/phones with some identical folders on them "documents", I want to save ALL documents from ALL sources into ONE folder on the NAS.

I tried using synology drive client but he won't le me save the files from various sources into a SINGLE folder, i have to create a "PC1", "PC2", "PHONE1" folders.

I don't care if there are some duplicate names, I just want ALL files into ONE folder.

So first of all is there a workaround this (other) limitation from synology drive client and if not what program should i use ?

the synology ecosystem is starting to look like a mac where you cannot do anything except what they want you to do...

Thanks for the help
