Rockboxed ClipZip delete files

[ZaxTS]

Hi i wanna ask you guys, although my rockboxed zip works fine, why cant i delete files from the .rockbox folder?? i delete them normally but they just wont disappear.....

My attempt to delete is because i somehow made a corrupted installation from the rockbox utility and got the ''plug the usb cable'' message (means that bootloader was incorrectly installed).
Then i tried the manual method and it works fine by now, BUT in the .rockbox folder there are subfolders with ''adsf===='' names that i want to remove.

Thnx for answers
