Sansa Sandsik Clip+ 8gb Internal Memory Full - no files to delete

It is possible that the File Allocation Table is messed up in your device.  The FAT is the master list that tells Windows how much memory is available, and the addresses of this memory.

If you connect the Clip+ in MSC Mode , either by selecting on the device Settings > System Settings > USB Mode > MSC, or alternately, you can do this manually by starting with the Clip+ turned off.  Press and HOLD the center button depressed as the device is plugged in to the USB port, and it will connect in MSC mode.

You can then use the following guide to Check the Volume For Errors and recover the FAT.  This problem will often give you the “not enough space” error; follow the procedure in the linked guide.  To those familiar with the chkdsk command-line utility, this is the same process, only handled via mouse clicks.
