Consider a script that deletes files older than 10 days in a directory (it can be used when you need to clean up the logs folder, or public network folders). the script should check if the files in the source folder exist anywhere inside the destination folder. $FolderPath = Get-ChildItem -Directory -Path "C:\temp" -Recurse -Force Delete files older than xx days using PowerShell. I need to compare many folders, which contain many files (millions) which are nested inside long file paths (> 260 char.) The input file contains a source and a destination folder. The final output ($Output) is then piped to Out-GridView so that you can sort and filter the results. A second ForEach loop formats each access control entry (ACE) into an ordered list, pulling out just the information that we need, making the results easy to read. Click File, Compare files In the top panes, navigate to the directory. The script below puts the folder hierarchy into a variable ($FolderPath) and then passes each folder to Get-Acl in the first ForEach loop. ScriptMerge is a stand-alone application shipped with PowerShell Studio 2015. If the destination file already exists, the copy attempt fails. Copy-Item -Path C:boot.ini -Destination C:boot.bak. Compare Two Directories with Powershell Posted on Januby jeff We use DFS to keep webfarm nodes’ content in sync and ran across a problem where a directory with thousands of files and folders had one missing file on a replica. So, if you want to know the permissions set on all folders in a directory tree, you need to use the Get-ChildItem cmdlet with the -Recurse parameter to list all the folders in the tree and then pass the results to Get-Acl using a ForEach loop. The following command backs up C:boot.ini to C:boot.bak: PowerShell. Get-Acl cannot recursively return all the permissions of folders in the hierarchy. The example below gets the permissions set on the C:\temp folder and all the available properties. The PowerShell Get-Acl cmdlet can be used to return permissions on objects like files, folders, and registry keys.
