`df` for DOS

Inspired by Unix

I have an 8 GB virtual disk attached to my development DOS virtual machine. Because MS-DOS 6.22 only supports FAT12 and FAT16 natively, in order to avoid wasting massive amounts of space with a large cluster size, I needed to partition the drive into quite a few partitions. This made it hard to keep track of how much free space I had where, and so, df for DOS was born.

Downloads

`df` for DOS 1.0 source
Description	Size	SHA-1 checksum

Subversion

https://svn.zive.ca/master/DF for DOS/trunk/

Build requirements

OpenWatcom C++ 1.9.
GNU make; on Windows, from Cygwin or MinGW.

Although the source contains a Visual Studio 2015 solution, which in turn contains a Visual C++ project, it is not required in order to build—df for DOS is built by a Makefile. I just like the Visual Studio IDE.
