Description
This command Erases an existing file inside
the current directory path. The received file
name must always include the. xxx extension
of the file. The security Un-Lock byte is a
simple double security byte that avoids
unwanted delete operations.
When deleting a File, it must be closed and
not allocated / mounted under any
workspace# to avoid data corruption.
If the file to erase doesn’t exist, the
command will fail with INVALID NAME(0x06).
