Ok, this one’s is cool i think. Whenever i needed a large dummy file, i opened up notepad, write ASDFASDFASDFA CTRL-A, CTRL-C, CTRL-V,CTRL-V,CTRL-V,CTRL-V. CTRL-A, CTRL-C, CTRL-V,CTRL-V,CTRL-V,CTRL-V,CTRL-V.. Then i saved the file, opened up a CMD-Shell and wrote copy dummyFile.txt+dummyFile.txt+dummyFile.txt until the file was large enough.. ok, there’s fsutil.exe which does the same in a much more efficient manner.. OR, unleash the Power of .NET – no, you don’t have to start programming using Visual Studio, just open up PowerShell.. | Image may be NSFW. Clik here to view. ![]() |
Ok, the goal is to have a 1gb large dummy file ..
first we declare a string variable called file:
PS C:\> $file = "$env:temp\dummyFile.txt"
no we create on object of type Io.File PS C:\> $objFile = [io.file]::Create($file)
on the object, we call the void SetLength parameterized with 1gb PS C:\> $objFile.SetLength(1gb)
no we call the close method and the file is written PS C:\> $objFile.Close()
using get-item $file we list the file we just created:
PS C:\> Get-Item $file
Directory: C:\Users\<removed>\AppData\Local\Temp
Mode LastWriteTime Length Name
---- ------------- ------ ----
-a--- 13.03.2010 14:07 1073741824 dummyFile.txt
PS C:\>
Ok, finally we can call an ii (Invoke-Item) to open the Path where the dummyFile resides in Windows Explorer.
To get the Path from a File, we can use Get-ChildItem (Get-ChildItems returns a FileInfo Object/Class). This object has a DirectoryName Property.
We declare an Object $path
$path = Get-ChildItem $file
Finally we call the mentioned ii (Invoke-Item) to open the path in Windows Explorer.
ii $path.DirectoryName
The complete Script
$file = "$env:temp\dummyFile.txt"
$objFile = [io.file]::Create($file)
$objFile.SetLength(1gb)
$objFile.Close()
$path = Get-ChildItem $file
ii $path.DirectoryName
