JSI Tip 3687. Batch script returns drive size and freespace.

Using GetSysInfo.exe, I have scripted GetDriveInfo.BAT, which returns the following environment variables:

GetDriveInfo.bat has one parameter, the drive letter you are querying. If you ommit the parameter, drive C is queried. If you query an invalid drive letter, jsisize will be 0.

GetDriveInfo.BAT contains:
