How to convert .DMS floppy image file extension

Ace McPlane · June 12, 2018

What's needed:

.Tsgui http://aminet.net/package/disk/misc/tsgui

.Workbench 3.1 (You'll have to find your own copy because I'm not a pirate)

.Virtual Floppy http://aminet.net/search?query=virtual+floppy

First off, when clicking on the download for a .dms file, it'll show up as a bunch of text in your browser. Just right click the file and chose to save the link to disk. Save it as a .dms.

step 1: Set up your Amiga emulator (winuae). Here's a guide for that http://guide.abime.net/home3.htm The workbench 3.1 disks are your operating system installation disks so you'll need those now. If you have trouble loading them from an external floppy drive, convert them to .ADF image files. This could be a problem since I don't know a way of converting them in windows instead of from the Amiga emulator. Comment if you know of a program capable of doing this. There's likely a way. I'm just forgetting.

step 2: Put tsgui.lha and virtualfloppy.lha into a directory, call it downloads and add that directory as a drive in winuae labeling the volume as downloads again. You need to use Amiga Dos to extract them. So, go to your system drive, go to system, then open Shell.

Type: lha x downloads:tsgui.lha downloads:

hit enter

Type: lha x downloads:virtualfloppy.lha downloads:

hit enter

Type: endcli

hit enter

NOTE: if you have any trouble with the steps below, you probably didn't install the Amiga installer or something else important in the guide to setup winuae so go back through that again if you have a problem.

step 3: Now open that downloads directory in your Amiga emulator and open up virtual floppy. Wait for it to load, go to the first Amiga tab and click on VH1, hit the first button on the left. Click on VH1 again and click the 2nd button from the left. It should now be a formatted virtual floppy on your Amiga desktop.

step 4: Open tsgui, highlight VH1 in the left column, then near the bottom you can find a file, click that and locate the .DMS file you want to convert (make sure you put it in a directory accessible to your emulator like that downloads directory we created). Now click the button to write the file to the floppy. It will will first say that the size of the disk doesn't match the size of the file.. Ignore that and now it will look like it failed giving you error 0 probably asking you to reinsert the floppy since it's now not going to work with Amiga. Just hit cancel.

step 5: Still in tsgui, highlight VH1 again in the left column, but this time hit the button to write the floppy to file.

Step 6: Hit F12, navigate to the floppy section and add that floppy image to DF0, DF1, DF2, or DF3 like you would with any other floppy.

It should come up as a working floppy now.

So there,

now you know how to do that. Not that you'll probably ever need to or that anyone even asked

but putting it somewhere online so the tutorial is there in case someone needs it seeing as this isn't exactly intuitive.

The funny part is that I'll probably be the only one who uses this guide like a year from now when I forget how I did this It's necessary if you want to open some old Amiga stuff like driver disks for the Picasso IV graphics cards.
