I have a Sony SJ30. My internet access was unexpectedly interrupted yesterday, and I couldn't email some of my work files to my email address (so that I could access them from work). My work computer has no external storage device (e.g. a floppy drive) but it does have a USB port, so I zipped the files and copied them to the memory stick. I don't have the original installation CD anymore, but I tracked down the Palm desktop software and that seemed to work. Sync-ing works but unfortunately, memory stick access does not. My next idea was to rename the file (.zip) to (.pdb) so that I could copy it to internal memory, sync it, then rename it, but whenever I try to move the file over, I get a "error occured while moving file to internal" from YiShow 5.3, or "current folder is access inhibit" from the internal launcher. Can anyone help? Thanks a lot.
