- What's this?
-
- DelZero is a AmigaOS 2.x/3.x DOS util
- that will change the size of a file to zero,
- then attempt to delete it.
-
- Why do I need this?
-
- Let's say you are _me_, and one day you managed to REALLY fill up your
- hard disk, you get an error the disk is full.
- But for some reason the system is unable to remove the uncomplete file,
- mainly due to the hard disk being so full that it can't change
- the disk root to tell the system the file has been deleted.
- And thus you can't use C:Delete because it need a functioning root block,
- and programs like DiskSalv and QuarterBack Tools etc.
- didn't work in my situation (perhaps later versions can handle this).
-
- So I wondered, hey what if I change the size of the file,
- fool the system into thinking the file is smaller, perhaps even 0 bytes.
- That's when I checked the excellent Amiga Intern manual,
- and found a AmigaDOS routine that allow me to do just that.
- Thus Delzero was born.
- After programming and compiling my little tool in my Ram: disk :-)
- I used it and tataaa, the annoying file became 0 bytes in length,
- and I was able to use C:Delete to remove the offending file.
-
- It may depend on the filesystem you use,
- but this COULD happen to you as well,
- so never fill your harddrive to the last byte,
- since it could complain to have no room to change the disk root
- bitmap block (it contains info on the disks files)
-
- A delete seems to need reordering of the root bitmap,
- while a filesize change just change a size value or similar.
- At least DelZero works, and saved me from formatting my HD,
- or formating it and restoring it selecting all files/dirs
- except the bad file..
-
- Since the initial version DelZero got it's DelZero name,
- and is able to delete the file itself (no need to use C:Delete for this)
- it has an option to disable the delete so you can use
- your favorite delete util instead.
- And messages can be silenced with a QUIET option,
- and file that are delete/write protected can be changed as well
- with the FORCE option (resets the protection bits of the file as well).
-
- Usage: DelZero file [nodel] [quiet] [force]
-
- file is the filename of the file to change to 0,
- or to delete.
- NODEL is a switch telling the program to not delete the file
- but leave it at a size of 0 bytes.
- QUIET will tell the program not to display any messages.
- FORCE will change the protection bits to enable delete/sizechange,
- in case the file was write/delete protected.
