Select Single Part Libs > Map Parameters > Import
Rename SchLibs
Usage: Make *.SchLib filenames that match the Symbol Refs or Library Refs. If a parameter named Symbol Ref exists the selected single part Schlib files will be copied and renamed to match Symbol Ref. If the Symbol Ref is not found the selected single part Schlib files will be copied and renamed to match the Library Ref.
Rename PcbLibs
Usage: Make *.PcbLib filenames that match the Footprint Refs.
After importing libraries into Parts, then Altium's Library Splitter Wizard should be used to remove parameters and models from the imported *.Schlib files leaving only the graphical Symbol in the *.Schlib files.
Notes: About illegal Characters and File names.
All illegal file name Characters must be removed from the Library Refs and Footprint Refs.
