The TLC import facility, when used with the TLC Export facility makes it incredibly easy to share TLC tabs and lyrics.  With a single click you can scan hundreds of songs, comparing them to those in your database and only import the new ones.  Just as easily you can import by category, title or author.  

The program can automatically rename files as they import or it allows you to rename and/or re-categorize songs manually.  You can even import the Tunings, Spell Checker Words and Chords from other TLC users.

To help manage your songs you can set a property on each that determines whether or not it will be included in the export.  You can also create unique or time stamp flags on each song as it is imported so they can be easily relocated and reviewed.
