There is an additional bug beyond the illegal characters (such as \) that causes the 'could not move to library' error. Closing down LimeWire and restarting it appears to fix this problem.

If you have run out of disk space, this may also contribute to the problem.

When files are being uploaded from you - LimeWire holds the file open, preventing you from moving or deleting the file. Sometimes LimeWire holds a file open even if it isn't currently being uploaded - this is a bug. Close down LimeWire, move or delete the files, Re-open LimeWire.
