Corrupt files
 

While uploading songs corrpt files are also automatically uploaaded in the player with some chinese player.......so all my space gets vanished as these files are impossible to delete......these folders are og 100 Gb of space

mpxproblem, What size memory does your player have. Try using the MP3 Player Disk Tool and give it a low level format. It could also be a virus as some member have reported there players arriving infected so give your system and the player a AntiVirus scan.
