I recently upgraded to 3.40 OE-A from 3.03 OE-C. Everything went smooth only everthing that I had customized went back to the original config. Not a problem since I backed up all of my 3.03 files. Now I have all of my files back except the system_plugin.rco file, which is the sounds you here when moving throughout the psp menu icons. When I went to the recovery menu, flash0, vsh, resource, to try and put the system_plugin.rco file in there, I got a message saying "Disk in destination drive is full". Are there files in the resource folder that I can delete to save some space and if so which ones. Thanks in advance.
