Hi. The trick is to get the songs imported, then MusicBee is able to automatically organize/rename the files, shortening them where required (but leaving the metadata intact). As long as your files are properly tagged, the filenames themselves are not important, so you could try bulk renaming them, trimming the excess characters, or you could try placing them (at least temporarily) in the shortest path possible, like under a root folder on your hard drive. Programs that may be helpful; mp3tag (for metadata) or Bulk Rename Utility (for filenames).
