Are you trying to delete all files in a directory or the entire disk? What are you really trying to do?

Is that a partitioned disk? Do you want to wipe all the files in a partition or wipe all the partitions?

There are system commands like format and fdisk which do that.

A drive and directory are two different things. A drive is all folders and files where a directory is a subset of the drive. You need to be VERY clear and understand what it is you want to do. formatting the drive will remove ALL files and folders on the drive.

Here is a wiki link to what format is

With that said, here is some code TO GET YOUR STARTEDs. I have not tested this code, since I do not have any drives that I want to format so you will need to review it and test it and make any changes neccessary, like throwing in a Warning to the user explaining to them that this will do:

CODE

static void FormatDrive( System.IO.DriveInfo drive) { if (drive.IsReady) { System.Diagnostics.Process format = new System.Diagnostics.Process(); System.Diagnostics.ProcessStartInfo psiFormat = new System.Diagnostics.ProcessStartInfo(); psiFormat.FileName = "format.exe"; psiFormat.WorkingDirectory = "%windir%\\systm32"; psiFormat.Arguments = drive.Name; format.StartInfo = psiFormat; format.Start(); psiFormat = null; format = null; } }

if you want to just delete files and folders in a directory do this

CODE

new System.IO.DirectoryInfo("c:\\temp\\").Delete(true);
