How do I transfer my Datablock Formats, Queries, TCC formats, and Arc Flash label designs?  Which PTW files do I need to copy?

These files are located in the \Lib folder of PTW32:

Datablocks: copy the compedit.fmt and Draw.fmt files.
Arc Flash Labels: copy customlabel.dat
Queries: copy Query.arc
Print Forms: copy Ptwforms.frm

If you are installing the same version of the program, you can simply copy these files over. If not, use the import button to copy the files.

Datablocks: Run > Datablock Format > Click import
Arc Flash Labels: Run Arch Flash > Custom label > Designer > Styles > import
Queries: Run > Query > import
Form Layout: Document > Form Layout > import
