The issue you are facing:
After the upgrade of NC, the update and backup files didn’t removed.
Since 17.0 NC, i have all versions of backups and NC files, it takes lots of storage, looks like each folder with 10+GB…
Is this the first time you’ve seen this error? (Y/N):

Steps to replicate it:

  1. Upgrade from old to a newer version
    Note: I see tose folders via SMB in windows, seems like they’re hidden
