How To Perminantly Delete???

How To Perminantly Delete???

How To Perminantly Delete???

(OP)
Does anyone know how to perminantly delete a file? using the INT21h delete doesnt remove the entry from the disk, just marks the space as free. But I found that if you try to resave something under the same name (after a delete) the program is unable to read the file back in again (I get all 5's). I assume that this is the 0E5h code or something.

Anyway, I would appreciate any help.

RE: How To Perminantly Delete???

As far as I know that IS the proper way of deleting the file.  It's not completely deleted but the FAT chain and directory entries are removed.

WHICH Int21h delete are you using?  FCB or handle type?

Was the file open at deletion time?

It is windows. You can call me crazy, but if I run the program from a pure DOS mode, there is no problem. From a DOS box, it errors on the second open (after a save and delete).
Must have something to do with the recycle bin or something, it wont let it access the file or something funky.
Thanks anyway.

Well... you can try checking if the file is in the recycle bin...
