I have a CATIA V5 file server services 6 users in a manufacturing dept.
I whould like to know which method to devide the users is ideal.
My first thought is to create 6 separate files (directories) + 1 common + master library files for administrator only. Each user can read from master library and save only to his own (named) file. They can use products, process,drawings only on their own directory. The common is only for communication. They cant save to another directory except their own.

My second thought is to create files according to machines type, work type like a tree shape + master library files for admin only. With this way all users can save everywhere mix each other. They can use the same products and parts.
Which method is better or safer or recommended for a middle industry?

I hope be understood
