KJams Music Folder
The "kJams Music" folder is the folder pointed to by the Advanced preference panel. This is where kJams stores any song files that you have manually ripped from CDs or purchased in a kJams Music Store. This folder is organized and maintained by kJams. You do not own this folder, you can not change things inside this folder, you must not rename anything inside this folder. Also you should never place anything in this folder yourself. The contents of this folder correspond to the database that kJams maintains. For this reason you must not attempt to manage it yourself, otherwise the database would become out of sync.
If you manually place songs within this folder (DON'T YOU DARE), and then you go to kJams and attempt to "Add To Library…" those songs, you will get an error telling you that the songs should already be there, and if not then you should pick the menu "Advanced->Special->Scan “kJams Music” folder for orphaned songs…". They should already be there because kJams expects that it already knows about every song in that folder, since that folder was created only by kJams ripping songs into it. It is saying that if there ARE songs in the folder that you are not seeing in the library, then most likely you have placed them there yourself, and that in order to see them you must instead scan that folder for orphaned songs. DON'T DO IT. This doesn't work. PERIOD. You have been warned.
If you want to change the location of the "kJams Music" folder, say to an external hard drive, then i recommend simply copying the existing folder to the location you want it (then you know it has the correct name), then change the preference under Advanced to point to the same folder at the new location, then delete the folder from the original location.
