Cannot delete or overwrite files

I'm not sure if this is a bug in XEMU, or if I somehow messed up my ROM, but I am unable to delete or overwrite files.

When I try: SCRATCH "FILENAME" ,8

I just get "?SYNTAX ERROR". I've tried using DELETE and ERASE with the same results.

If I try to overwrite a file I get 63,FILE EXISTS,00,00

So every time I want to save my work I have to create a new file.

Am I doing something wrong?

Thanks, that helped somewhat. Dsave, delete, scratch, and erase all result in a syntax error, but if I save the file with the @ in front I can at least over write it.

Is there anyway to unwritelock the sdcard image?

Thanks! The "u8" switch worked, although I still can't delete files that start with "@". Is there a different command or switch for those?
