File Name Uniqueness
If this check box is selected, in the General
Option of PLM preferences, the names of the
files stored in PLM are maintained as unique.
If this check box is cleared, you can store multiple files with identical file names in PLM but in different projects. It is not recommended to clear this check box, since it might cause problems if you want to download a file while a file with an identical name already exists locally. For example, you cannot use multiple files which have identical file names; from different folders; in one assembly.
