I created document libraries in Sharepoint 365. If I then synchronize this with my PC, the name of the Sharepoint site will appear for each folder. If I remove this name, it will be the name that appears in the Office365 management portal has been created (instancename). It then looks like NAME - MAP NAME Can I hide or delete the site name for the folders?
@Bas_B Are you referring to the way your document libraries look in file explorer after you've synced, like this?
I get an error when I try to rename that "folder" (that's what you'd have to do to hide the site name). I'd argue this isn't a big deal--if you're syncing document libraries from multiple sites, you quickly enter a scenario where you might have document libraries with the same name in different sites, and you certainly do at least for the out of the box Documents document library. Microsoft would have a serious user-experience problem on its hands if it defaulted to carrying over just the document library name instead of both.
I don't have an answer as to why Microsoft doesn't let you rename locally. I can make a wild, unfounded guess--it might be that, while syncing libraries carries over all the rights you have against the document library, Microsoft has deemed that renaming the folder--which is at least the same as renaming the document library itself--isn't something that the sync functionality should allow someone to do.
