    I lifted the following code from another board and made a couple of changes to it. The purpose of the script is to move files older than 400 days from source to destination, while maintaining the original path information. What I've run into is the folders, nested several layers deep are often over 400 days and are also being moved. I'm a complete noob to PowerShell and could use some help.

    How might I step through the subfolders but only move files, maintaining the path of course. I just don't want it moving the sub folder structure from the Records folder.

    Thanks for any and all help.

    $Source = "D:\Records\"
    $Destination ="D:\Archive\"
    $Past = (Get-Date).AddDays(-400)
    $List = dir $Source -recurse | Where {$_.CreationTime -lt $Past}
    foreach($file in $list){
    $MovePath = (join-path -path $Destination -childpath $file.FullName.SubString(3))
    $MoveDirectory = (join-path -path $Destination -childpath $file.DirectoryName.SubString(3))
    new-item -path $MoveDirectory -type directory -ea SilentlyContinue
    move-item -Path $file.FullName -destination $MovePath
    }

    I don't understand, sorry.

    If the source file is C:\This\Path\Is\Really\Long\file.txt

    You want it moved to:

    C:\Archive\File.txt

    Or

    C:\Archive\This\Path\Is\Really\Long\File.txt

    To me, there seems to be a conflict between "maintaining the path" and "not moving the sub folder structure." Give me a quick example of what the starting path for a file looks like, and what you want the end path to look like.

    I would like to move the files only

    Source C:\This\Path\Is\Really\Long\file.txt

    Destination C:\Archive\This\Path\Is\Really\Long\File.txt

    For instance, regardless of the date on the folder, I wish to maintain the folder in the current location.

    If the date of any file in any subfolder of the source tree is less than 400 days old I with to move the file, replicating the directory structure and placing it within the destination folder.

    AH. So what you REALLY want to do is just exclude folders, and only get files. In v3, that's easy, because there's a switch on Get-ChildItem (Dir) that will return only files. It'll still recurse subfolders, just not list them.

    In v2, you'd have to add a clause to your Where statement.


    where { $_ -is [System.IO.FileInfo] -and $_.CreationDate -lt $past }

    That way, folders aren't even considered for moving – only the files in them. The file itself has all of the information needed to construct the destination path, which it looks like is already happening.

    Thanks for the assistance, I used your suggestion and learned a couple things along the way. Wish I had more time to delve into this scripting language, it looks very powerful.
