I'm running OS X 10.5. I have one main directory with subdirectories at the album-level mostly. Jaikoz complains after about 5000 files i think? Tells me to change the memory settings in a startup file, but I don't know where that is. I did a search on the forum and it talks about jaikoz.lax but i can't find that file either.
Jaikoz is being improved in the next release to allow you to select multiple subfolders in one go, and to use memeory management techniques to allow
more files to be laoded with existing meory limitations.
