Hi
I am trying to get MD5 hashes of folders with sensitive information . I have found the link below. However when l run a test to compary the folders. I do not get any response from Powershell. I have upgraded the version of Powershell to version 3 and  I have imported the PSCX modules to enable it to work. I would appreciate any assistance.

I did some quick tests and my results are as follows.  When the two directories have exactly the same contents, there was no output at all. I changed a single file and the output is as expected.

I would recommend double checking your folders, make sure you have contents that are different.

Okay thanks l will run a test as well with sightly different contents, however is there a way to see if the MD5 check is still running as l have a few folders that l have  copied that have similar data but contain terabytes of data, that l need to verify contain the same data.

i suppose if you are comparing TB's of data you should see powershell.exe in your task manager using some resources
