Skiro'n, Wow I am unsure who to thank. I had quite a bit of trouble getting this going, not sure why. I am running Feisty and for some reason the previous File manager would not work. I read through the first twelve pages and saw there were a few similiar problems but I was always getting the ????? ./OMGAUDIO ????? I could leave it open and click around and eventually I would get rid of the ?????... and it would scan, but the add files in lower right hand corner was grayed out and did not function. After several hours I was finally going to try it on Windows as I went through the error code 00005e36 problems earlier but thought I would give it a try, then I go to the last post here about JSymphonic, I downloaded it and did not really read the read me, just glanced at it and already had the OMGAUDIO on the player so I replaced the jar files to the new JSymphonic and added the XML just to be safe and VIOLA in a split second was able to transfer files. I am not sure why I had so much troubles with Patrick's version, I had tried it a few months back on a previous Feisty and it behaved the same way and I installed it correctly. However thanks a lot Patrick for without your great work on the NW-E00x there would not be this player. Funny thing is, I had Gparted open and was going to try to format it however Gparted did not find the device, although it was found and identified by Ubuntu. I then plugged in a card reader and Gparted found my memory stick, unmounted and remounted my Sony and Gparted could not find it. Anyways JSymphonic worked like a charm right out of the box and I did not have to revert back to Windows. Thanks for the great program and I am still scratching my head as to why the other was not working, it seemed like it was trying because it would eventually find the OMGAUDIO folder after starting out with the ????/
