If you accidently delete a file from disk, there is a way to make it visible again.

''Important!'' Don't not save anything to disk after deleting because it will be impossible to recover your files then.

type this:

poke &a701,229
cat

now you will see all the deleted files that are still stored on the disk.
you can '''load"''' a basic file, then type

poke &a701,0
save"filename

and it will be saved again.

For other non-basic files you'll have to use a disc tool like discology.


This is how it works:

This poke does the same as the ''|user'' command from amsdos. The ''|user'' command can only access user 0 to 15.

When you delete a file mit ''|del'', AMSDOS rewrites the user level of the file with number 229. So, when you change to this level, you will see the deleted file again.
