hello balder ,I've forgot how do with the image file "dos.img.gz" in my usb-hdd which is in the image folder.
I know how to extract the .img.gz file (with winrar) , but after I add something in it. I forgot how the compress it back to "dos.img.gz"
My menu.lst is :
title DOS Big Floppy Disc
map --mem /IMAGES/dos.img.gz (fd0)
map --hook
chainloader (fd0)+1
rootnoverify (fd0)
boot
Thanks

@allgames71Hi again @allgames71

Hmmm... Interesting question @allgames71
First of all - you actually don't need to use gz-compressed floppy image-file.
You can run it as it is ***.img or ***.ima
In fact you can launch floppy image using: run ***.img
But if you decide to compress floppy image to gz-format you are bound to use grub and "--mem" command to launch compressed image from RAM (which is exactly what you show).
However request was about how to easily get image back to the gz-format
I use TotalCommander and UltraIso to manipulate gz-compressed floppy images (TotalCommander has built-in support to directly open gz-compressed images)
I simply open gz-compressed floppy image in one of the two windows in TotalCommander and "drags" (extracting) image to the other window.
I of course use UltraIso to open extracted floppy image in that other window and using UltraIso I 'drag' (extract) file(s) from floppy image and also 'injecting' back (drag) extracted file(s) back to floppy image.
I save changes to floppy image followed by 'drag' saved floppy image back into the window that still holds my opened gz-image.
I save changes when asked to ez-compressed image and that's it
However you can also use my script "easyboot-cab.script" and push on button "G-ZIP"
Script ask for location of file to run g-zip to and that's it

hello balder,According to your instruction , Total Commander is the best for making .gz file. Thanks a lot.
But my "dos.img.gz" is not in my dvd , if it's in dvd , it's easy and I managed it already. But I really forget how I put this "dos.img.gz" in my usb-hdd with the menu.lst like this :
title DOS Big Floppy Disc
map --mem /IMAGES/dos.img.gz (fd0)
map --hook
chainloader (fd0)+1
rootnoverify (fd0)
boot
I forgot how to make this big floppy image (25.7 MB) like this in .gz way. Anyway thanks for you instruction. Thanks

@allgames71Eeee... is your problem solved - or....
I suggest you always put in the 'autosearch'-command 'find --set-root'
Below is the recommended lines to use in your case
Note: 'boot' in the end is actually not needed - so I skipped that line
title DOS Big Floppy Disc
find --set-root /IMAGES/dos.img.gz
map --mem /IMAGES/dos.img.gz (fd0)
map --hook
chainloader (fd0)+1
rootnoverify (fd0)
