VBS and FSutil Query

[trevorh13]

I am an IT Trainer and am preparing some disk images for our students to use in troubleshooting labs. I need a script that I can run that will query the freespace on c: save the result to a variable that is then passed to fsutil to create a file filling up the hard disk. (my students need to identify that the 'user' cannot save a file because the hard disk space is exhausted. I am not a programmer but have managed to stitch together the following script from various places.

Set objWMIService = GetObject("winmgmts:")
Set objLogicalDisk = objWMIService.Get("Win32_LogicalDisk.DeviceID='c:'")
FileSize = objLogicalDisk.FreeSpace
Wscript.Echo FileSize
Set fso = CreateObject("Scripting.FileSystemObject")
set shl = createobject("wscript.shell")
shl.run "fsutil file createnew C:\incredible.hlk" FileSize,0,true

The wscript.echo filesize is showing the freespace so I am confident that the problem lies in the last line.

Could anyone offer me any advice on where I am going wrong?

Kind regards

Trevor

Your FileSize needs to be part of the command string. Try

shl.run "fsutil file createnew C:\incredible.hlk" [b][red]&[/red][/b] FileSize, 0, true

Hiya,

Thankyou for responding. I have amended the last line as you describe but the file is not made on c: and no error is reported.

Anybody got any ideas?

Kind regards

shl.run "fsutil file createnew C:\incredible.hlk " & FileSize, 0, true

Hope This Helps, PH.

My bad. I second PHV. Please note the trailing space after .hlk.

Many thanks to both of you for your invaluable assistance. I also found that I needed to include Wscript.Quit as the last line for the file to be created.

Once again ... many thanks

Kind regards
