C#, Disk information for remote computers
(Kristofer Gafvert)Purpose
This sample application will look up all computers in the file computers.txt, and find the logical drives, their size, name, free space and file system.
Usuage
Write the IP or name of the computer in the file computers.txt (hard coded name), one on a line. This file must be located in the same folder as RemoteDiskSpace.exe. Start the application by either double click the file, or run it from a command prompt. Do this on a client computer, there is no need to copy any files, or change anything on the remote computer(s).
Output
The application will create a html file (diskSpace.html), with information about disks, size of the disk, free space and file system in the same folder as RemoteDiskSpace.exe is located.
