Question

Ihave started a simple script in order to move files of a certain prefix to a folder of the same name eg: W100_11.jpg W100_12.jpg in to folder W100.

Thanks to help from the answers below I have progressed and have a successful loop which can iterate through the file sin the folder, I am having issues with the -filter switch and when trying to use the move-item cmdlet I am getting errors

The current code is:

$sourceDir = read-host "Please enter source Dir:"
$format = read-host "Format to look for with .  :"
#$length = read-host "length of folder name:"

gci -Path $sourceDir | % {
    If( -not $_.PSIsContainer)
    {
        $path = $sourceDir + "\" + $_.Name.substring(0, 3)
        $_
        if(-not (Test-Path $path))
        {
            mkdir $path

        }
        move $_.fullname $path

    }  
}

I am still having issues when using the -filter switch. This is a partial solution to the issue

The code below shortens your for loop and shows an example of using substrings on file names. You get a FileInfo object from the Get-ChildItem (gci) call, so you need to use it’s property Name to do substrings. See MSDN for more info on FileInfo.

$sourceDir = read-host Please enter source Dir
$format = read-host Format to look for with .  

gci -Path $sourceDir -filter $format | % {
    If( -not $_.PSIsContainer)
    {
        $path = $sourceDir + "\" + $_.Name.substring(0, 3)  
        if(-not (Test-Path $path))
        {
            mkdir $path
        }
        move $_ $path
    }  
}
