adding entire library-- 204gb...

So after I bought a new computer I decided to just throw everything on my external hard drive and re-do my library.

I had some issues with itunes match since the file paths' used my old computers' pathand not the new one, so playing from my computer was not possible, it played from the stored file and anything not on match wasnt accesible... ANYWAY

I tried to add my entire library and it only got to 20gb, about 2200 songs, or Aq. Its not like it skipped certain files, it just went all the way up to Aq, (by artist) and that was it.

Any suggestions?

I guess the logical choice would be to just turn everything into alphabetical folders and add 20gb at a time, but that would be a pain in the ***. I will, however,update this if that works.

Win 8.

Thanks.
