The catalog is on my macbook, all the photos are on the NAS, I can see the photos, everything is working fine, i can work on the photos. But only on the photos that I already have on the NAS, I can't import new photos.
When I try to do so, I have the following error message (I translated to english, the message is in french):
Your disk "XX.XXX.XX.XX", from where you want to import photos is running out of space.
Delete files or empty the bin to save up at least 250Mo of space before continuing.
