The issue you are facing:

(edited for clarity)


I have problems with my following setup:

  • Admin user who owns all the data and has a big quota.
    Example folders would be:
    • “Pictures” with subfolders:
      • “Clorge Jooney”
      • “Cars”
    • another top-level folder “Videoclips” with subfolders:
      • “Short clips”
      • “Clorge Jooney”.
  • Some “single” users, let’s call one of them User A.
  • Admin shares with User A:
    • “Pictures”
    • “Videoclips/Clorge Jooney”
  • User A now sees two folders:
    • “Pictures” with subfolders “Clorge Jooney” and “Cars” within it
    • and on the same hierarchy level as “Pictures”, he sees “Clorge Jooney” from the single shared subfolder of the “Videoclips” section.
  • Now User A gets confused and wants to tell the “Clorge Jooney” videoclips folder (which he sees right in his top-level directory) apart from the “Clorge Jooney” folder inside his “Pictures” folder. So he renames his top-level Clorge Jooney folder into “Clorge_clips”.

As far as I know, since everything that was shared with User A belongs to the Admin user, User A should be able to create stuff inside those folders etc., and everything would count towards the quota of the Admin. As stated here:

Now what I CANNOT understand is: After User A has renamed the folder on his end, it seems like the renamed folder’s size starts counting against User A’s quota. I have no way to check the “contents” of User A’s quota (at least none that I am aware of), but as soon as User A renames something and his desktop client performs a synchronization, User A’s quota starts to fill up.

Why is this? I thought the shared folders could be named as the users want them to name, because NC identifies them via some sort of database id anyway, and therefore it did not matter which names the users would give to their folders?

(I did this setup to prevent my Users to eat so much quota individually that my server would be out of space.)

Please help! How can I resolve this? What I would like is the setup as described above, but with the Users being able to name the folders as they prefer.

Greetings to all!
