General Options: Directories
Under General Options, Directories options allow you to get the paths for Project, Temp, SysLib, UserLib, and PersonalLib directories.
Use the [...] buttons to browse to paths and click OK. You will need to select Override to change the Temp directory.
If you need to restore defaults, click Reset Library Directories.
Note: If you modify SysLib, UserLib
or PersonalLib paths through Tools > General
options, the User Defined
Primitives menu should reflect those changes on next startup.
