Hi Nancy, thank you for the tips about how to menage the libraries! In the mneantime, doing various tests, i have found the REAL problem of my library:

Basically it doesn't read the names of the folders. For example, if i want to see the combat poses, inside the foler "combat", and in the field i search for "combat", nothing appear. But if inside that combat folder there is a file named 001, and if i search "001", i find it.

I were used that if on my PC i was searching for a combat pose, to search for the folder name, not for the file name, which i think it's pretty normal (if you search for 001 there will be hunderds of results). Now, i don't know why on Mac, my library is not able to read the folders, where the files are.

If i search for "M4" he will find the objects, poses, etc. that have M4 in the file name, but not the folders that contains M4 files, even if that folders are M4 labeled.
