For upload test in SharePoint, I had to create files of specific size, 10 MB, 20 MB, 30 MB, 40 MB, etc. Figured out a nice command line tool to create files in specific size. FSUTIL
fsutil file createnew c:\test.doc 10485760
This will create 10 MB file.
The same can be achieved with PowerShell too:
$FilePath = "C:\Test.doc" $File = [io.file]::Create($FilePath) $File.SetLength(1MB) $File.Close()
