OK, so you got yourself FloppyEmu or a similar disk emulator for your old Mac and it works great, except not with all the files.  Why? Because FloppyEmu and such disk emulators are... disk emulators.  They expect you to feed them a disk image, not just random loose files.

So just how can you wrap loose Mac files inside a disk image for use with FloppyEmu? Here's a full tutorial:

1) Grab a copy of this Disk image wrap tutorial Mini vMac package that I put together for you.  It's essentially just Mini vMac with a stripped down System 7 OS and various useful utilities sitting on the desktop.

2) Launch ImportFl that is sitting next to the trash icon on the bottom right corner of the desktop.

3) When it says "Ready to import..." then drag and drop the file that you want to wrap in a disk image on the Mini vMac desktop and save it to a location you want inside Mini vMac.  I would suggest that you pull down the top dropdown menu and select Desktop.  Then hit Save.

4) If your file is encoded or compressed (such as .sit, .bin, or .hqx for instance) then drag and drop it onto the Stuffit Expander 5.5 icon.  There are also other tools to extract desired files that need to be wrapped in a disk image, such as Disk Copy 6.3.3 for .img DiskCopy images and Virtual CD/DVD Utility for larger ISO and Toast images.

5) Once your files are uncompressed/decoded then all that's left is to copy them onto a blank disk image.  I have put a blank 800KB DS floppy disk image and a blank regular 1.4MB floppy disk image in the package folder for your convenience.  So what I suggest you do is duplicate one of them to always keep a blank one as stationary.  Then drag and drop that duplicated disk image on the Mini vMac desktop to mount it.  Then copy your files on it and you're basically done.  Of course, rename the floppy disk icon to something more relevant than "1.4MB floppy" and then eject it.  Rename the "1.4MB floppy - Copy.dsk" file to something more relevant too and you're done.  It's ready to be sync'ed with FloppyEmu or cloned onto a real floppy disk if you're a real hardcore retro-enthousiast! ;-)
