Title
Body
I am trying to recurse through a directory and copy it from A to B. That can be done with the following: Copy-Item C:\MyTest C:\MyTest2 –recurse I want to be able though to only copy new files (ones that exist in src but not dest) and also only copy files that may have changed based off a CRC check and not a datetime stamp. $file = "c:\scripts" param ( $file ) $algo = [System.Security.Cryptography.HashAlgorithm]::Create("MD5") $stream = New-Object System.IO.FileStream($file, [System.IO.FileMode]::Open) $md5StringBuilder = New-Object System.Text.StringBuilder $algo.ComputeHash($stream) | ` % { [void] $md5StringBuilder.Append($_.ToString("x2")) } $md5StringBuilder.ToString() $stream.Dispose() This code gives me a CRC check on a specific file...I am just not sure how to put the two scripts together to really give me what I need. I also don't know if the CRC check above is actually the correct way of doing this. Does anyone have any insight?
