1st I suggest rebooting your tablet if you don't normally power it down. This will deal with any program faults that had memory leaks. Next is moving data to the 2GB internal drive. Most aps let you specify where data should be stored and retrieved from. File Manager can used to move data. Also consider removing any applications you've installed but don't use. Lastly you can clean things up a bit from the command line. Install sudser to get "sudo". In a terminal run "sudo apt-get autoremove" to remove any installed but no longer rtequired packages. Then run "sudo apt-get autoclean' which will erase old archive files. This works for me without having to enable virtual swap memory.
