I have looked at this question: Recursively copy a directory entirely as symlinks, preserving current symlinks and if I'm reading it right I want to do the same thing but in Windows.

So, I have this:

Dir1\Dir_A\File.ext
Dir1\Dir_A\Dir_A_A\file2.ext
Dir1\Dir_B\File2.ext
...

I want that directory structure to be the exact same on the target directory minus the Dir1 but all the files to be symlinks pointing to the source files. So, I end up with this:

Target_Dir\Dir_A\File.ext <- file is symlink, folders are created
Target_Dir\Dir_A\Dir_A_A\file2.ext <- file is symlink, folders are created
Target_Dir\Dir_B\File3.ext <- file is symlink, folders are created
...

How can I achieve this? I'm also looking for a batch script or something that can be executed on a schedule to copy the new files every so often skipping the already created symlinks, kinda like a synchronization job minus the real copying of the files but instead (sym)linking them.

  • @PimpJuiceIT Thank you! That is exactly what I was requesting. It works well except for just one thing, I have a folder which name has a "!" character in the end and the batch has copied the folder without the "!" character and also has created a file with the folders name. To be more precise the name is like "AAAA AAAA! (1234)" and the batch has created a folder named "AAAA AAAA (1234)" and a file named "AAAA AAAA.mkv" (without the numbers on the filename), how can I fix this? The file points to a file with the same name in the source dir but that file doesn't exist.

  • I have also noticed that all the files that had a "!" in their filename has been copied without that character.

  • @DavidPostill Thanks! And sorry, I don't get it. What should I change in the pure batch script?

  • @PimpJuiceIT Yes, after some testing I also got the batch to copy some files but no others, and after a subsequent test it didn't work at all, I don't know why it worked that one time. Would be awesome if you could make a Powershell script to see if maybe this doesn't happen in there. Thanks!

PowerShell: Recursive folder copy with symbolic link files

You can use get-childitem to create an array variable and loop over the iterated object properties with some conditional if logic to help create a workable solution for your needs.

Essentially this...

  • creates a source-matching destination folder structure
  • creates a source-matching destination symbolic link file structure pointing to each source-matching file

You only need to set the $src value to point to the source root folder location and the $dest value to point to the root destination folder location—the other logic will do all the rest.

$src = "C:\Source\Folder\"
$dest = "C:\Destination\Folder\"
$src = $src.Replace("\","\\")

$i = Get-ChildItem -LiteralPath $src -Recurse
$i | % { Process {
    $apath = $_.FullName -Replace $src,""
    $cpath = $dest + $apath
    If(!(Test-Path (Split-Path -Parent $cpath))){New-Item -ItemType Directory -Force -Path (Split-Path -Parent $cpath)}
    If(!$_.PSIsContainer){If(!(Get-Item $cpath -ErrorAction SilentlyContinue)){New-Item -Path $cpath -ItemType SymbolicLink -Value ([WildcardPattern]::Escape($_.FullName)) -Force}}
    }}

    @Churchill .... One thing I noticed testing from a non-admin account, in order to create symlinks, I had to elevate permission. Keep this in mind as you test just in case you have the same issue. Jun 29 '20 at 3:04

    Run powershell.exe -ExecutionPolicy Bypass -File "C:\Scripts\AnyPScript.ps1" just like that from a batch or cmd to execute the logic within the Powershell script. I assume you are already familiar with that too but just in case I wanted to mention. Jun 30 '20 at 17:29

    Thanks! I've tested this with all my files and it works great. Thanks for all your time helping me.
