Verify file copy in powershell

Question

Is there an easy way to verify all files were copied correctly when calling copy-item? I thought about using the checksum on all files, but I would imagine powershell (v2) would already have something, and I can't find it.

Answer 1

No there isn't and here is why. Copy-Item is a generic cmdlet that works for all namespace providers. So the items being copied could be files, or registry settings, or IIS configuration sections, etc. Verifying a file copy is quite a bit different than verifying a copy of registry settings.

So if you are doing file copying and really need verification, there is always good old XCOPY. Still works fine from PowerShell.

XCOPY source destination /V
[tastes great, less filling] ;-)

Answer 2

I know it's an old thread, but I thought I'd post this just in case anyone else is reading it... the /v switch DOES NOT verify the data! It just makes sure that the copy is readable. See http://support.microsoft.com/kb/126457 for details.
