If you change the location of your download folder, the incomplete folder will follow automatically. There is the question of incomplete files in hand and there is a possibility these will become unuseable. There are two files in Mac these are downloads.bak and downloads.dat In windows possibly something different ... but they are important in keeping these files useable and I'm not to sure what happens if you try to move them. a search (above right) on either of these file names should lead you to other useful posts. If you have no important incomplete files you will have no problem

My save folder is on a different drive from Limewire. Gives me no problem
Just specify in preferences/option the new location in saving > save folder.
