Synology - Cannot see any folders in share when adding media library

Yep.. It appears your permissions were manually edited in FileStation as well.
This isn’t a problem.

  1. Keep those share permissions where they are. This is how it should be done.
  2. You now need to also grant permission in each of the subdirectories. it’s likely you’ll need do this from now on unless you create a new share for your data and let DSM work in default mode.

The corrective action is done in File station.

For each of your subdirectories in DATA,

  1. Right-click
  2. Properties
  3. Permissions tab
  4. Owner = R/W/E, Group & Other = R/E as shown below.
  5. Make certain to check “This folder, sub-folders, and files”
