Compression. My mate got a floppy up to 80MB once. Only works well with stuff that compresses really well, like text files and word documents.

I have a CD (Windows 2003 10 in 1), that I downloaded and burnt on a regular 700mb CD. On that CD there is a folder (ROOT) that was 4.9gb!

Is this compression or witchcraft or something more sinister?

The floppy trick worked for me only under Win9x. I was able to store 1.66MB, but WInNT/2000/XP can't read the disks

That screenshot I showed was in a 2000 system...
I'll take a screenshot of the same floppy in XP if you like...

I'll tell you how it ended up like this later.. :wink:

This is not (only) compression, it also involves symbolic links to files that are the same among the various versions of Server 2003. The various files you have on the CD appear to be there multiple times, but in reality, they're only on the CD one time, the other files you see are just 0-byte symbolic links. But Windows doesn't understand these and thus thinks these links are real files, and that's why you get this ~5GB folder on a 700MB CD.

An example: explorer.ex_ is the same in all 10 versions, so you'd have 10 times the same file and a good amount of wasted space. What you do is: store explorer.ex_ on the CD once, then create symbolic links to that one real file in all other locations this file would normally be stored in. So, in reality you have only one real explorer.ex_ file and several "pointers" to that one, but Windows thinks the file is stored multiple times, each of them taking up space.

Symbolic links are nothing uncommon, at least not in Unix. In theory, you could compare them to the "shortcuts" on Windows, but they're more.

That's just because the guy who made that CD used cdimage with the -o switch.

It's also possible with a quad-density (2.88MB) floppy drive. They work with standard floppies, but allow for higher capacities. It's also possible with messing up the file system. I once made a floppy appear like it was holding several terabytes of data.

You guessed it . :wink:
I originally formatted the floppy on one of my beta testing systems that
had NT5 1631 on it, then transferred a screenshot via floppy to my
main system..
A couple of days later I needed a floppy to transfer Belarc to another
system as I was given a bunch of dead systems that all had 10gig
drives in them..
I usually put the drives on another system, run them & extract any
OS & office numbers if any...
I put the floppy in my 2000 system & just single clicked the drive to
check it's contents, which it said it was empty, so I transferred Belarc to
it & still transferred OK to the other systems...
I just kept throwing files onto it until Windows said it was full...
It seems that NT5 formatted it in a way that 2000 wasn't familiar with,
even though it still read & copied from the disk..

I'm half asleep at the moment so are the floppy disks actually holding this amount of data?
