The problem is how you called the PS1 script. I presume that you are calling powershell from cmd.exe. In this case you have to do this:

M:\document\WindowsPowerShell>powershell.exe ./Get_Duplicate_Files.ps1

You missed the "./"

Now if we could only find out why powershell chokes when asked to just do it's job and run the script:

M:\document\WindowsPowerShell>dir

Volume in drive M is Data

Volume Serial Number is 0CE7-363C

Directory of M:\document\WindowsPowerShell

17/10/2007 04:25 PM <DIR> .

17/10/2007 04:25 PM <DIR> ..

17/10/2007 04:25 PM 645 Get Duplicate Files.ps1

17/10/2007 03:55 PM 716 Microsoft.PowerShell_profile.ps1

2 File(s) 1,361 bytes

2 Dir(s) 131,402,600,448 bytes free

M:\document\WindowsPowerShell>powershell.exe Get_Duplicate_Files.ps1

The term 'Get_Duplicate_Files.ps1' is not recognized as a cmdlet, function, operable program, or script file. Verify the term and try again.

finding duplicate files based on lastwritetime and length.

get-childitem -force -recurse -erroraction continue | sort-object lastwritetime,length | Group-Object -Property lastwritetime,Length | ? { $_.count -gt 1 } | foreach { $_.group | select-object directory,name,length,lastwritetime } | export-csv files.csv
