There is only one reason that you could ever 'need' to move files 'from' BearShare 'to' LimeWire... That would be so that LW would have a definitive list of those files that you have already successfully downloaded.

Neither BearShare nor LimeWire should have anything to do with the 'final' storage folder on your machine.

Best thing that you can do is to create a new folder - probably in your 'My Documents' folder - and Copy or Move your files to this appropriately named new folder... doing the Copy and or Move functions with Windows Explorer...
You could create a main music folder called, maybe MUSIC BANK... Create another called something like MY SHARED FILES... Copy some of the stuff from 'the BANK' to 'the SHARED' folder...
Main thing is to start out in the beginning with a fairly clear idea so that you can manage your files as they grow in number... Lots more on this subject for the future...

The storage of your completed files should be independent of any p2p application folder.

Let us know how you get on... !

p.s. Please do not automatically allow sharing of your DownLoads or Incomplete folders... Reason is that if you ever share un-checked (tested and proven) files, you have no right to complain about D/Ling bad files from other ! Right ?
