In PowerShell how to display filename in the output of compare-object

I am very new to PowerShell scripting.

I have two folders with hundreds of files with the same name in both folders. I am writing a long script to compare all the files and send output to a text file. When I use this script:

compare-object  (get-content "D:\Folder1\file1.js")  (get-content "D:\Folder2\file1.js")
compare-object  (get-content "D:\Folder1\file2.js")  (get-content "D:\Folder2\file2.js")
compare-object  (get-content "D:\Folder1\file3.js")  (get-content "D:\Folder2\file3.js")

All I get is this:

InputObject SideIndicator
----------- -------------

     * New Text =>
     *          <=

This doesn't tell me which file has this difference. I want it to display the file name also (anyone, first or second file name).

How can I achieve that?

I know I should be using Get-Children, but I need to learn the simple thing first which can be implemented in a loop.

Solution

With kind help of participants I have managed to create the following script that might be helpful for others:

$ErrorActionPreference = 'Continue'
$output = "result.txt"
del $output
get-Date >> $output
Get-ChildItem -Recurse -Path 'D:\Compare\Source\' -Include @('*.js','*.txt', '*.html', '*.css', '*.mxml') |
Foreach-Object {

    $f1 = $_.FullName
    $f2 = $f1.replace("\Source\","\Comparewith\")
    echo "`n" >> $output
    echo  $f2 >> $output
    Test-Path -Path $f2 -PathType Leaf >> $output
    compare-object  (get-content $f1) (get-content $f2) >> $output
}
get-Date >> $output

Basically I have two folders. Source and Comparewith. I am picking up each file from the Source folder as $f1, creating a similar file name $f2 while replacing Source with Comparewith but keeping same file name, and then comparing both. I am using echo to print the name before each compare-object and also testing if the file exists in the Comparewith folder.

Any improvement suggestion are welcome.
