compress-archive and preserve relative paths

Question

I\'m having a challenging time getting compress-archive to do what I want...

I have a root project folder and I want to zip up some of the files in sub

Answer 1

The cumbersome technique mklement0 mentioned worked for me. Below is the script I created to support a list of various files mixed with folders.

# Compress LFS based files into a zip
# To use
#  1. place this script in the root folder
#  2. modify the contents of $lfsAssetFiles to point to files relative to this root folder
#  3. modify $zipDestination to be where you want the resultant zip to be placed
# based off of https://stackoverflow.com/a/51394271

# this should match files being .gitignored
$lfsAssetFiles = 
"\Assets\Project\Plugins\x32",
"\Assets\Project\Plugins\x64\HugePlugin.dll"

# This is where the contents of the zip file will be structured, because placing them inside of a specific folder of the zip is difficult otherwise
$zipStruct = $PSScriptRoot + "\zipStruct"

# the actual zip file that will be created
$zipDestination = "C:\Dropbox\GitLfsZip\ProjectNameLfs.zip"

# remove files from previous runs of this script
If(Test-path $zipStruct) {Remove-item $zipStruct -Recurse}
If(Test-path $zipDestination) {Remove-item $zipDestination}

Foreach ($entry in $lfsAssetFiles)
{
  # form absolute path to source each file to be included in the zip
  $sourcePath = $PSScriptRoot + $entry;

  # get the parent directories of the path. If the entry itself is a directory, we still only need the parent as the directory will be created when it is copied over.
  $entryPath = Split-Path -Parent $entry

  # form what the path will look like in the destination
  $entryPath = $zipStruct + $entryPath

  # ensure the folders to the entry path exist
  $createdPath = New-Item -Force -ItemType Directory $entryPath

  # copy the file or directory
  Copy-Item -Recurse -Force $sourcePath $createdPath
}

Add-Type -AssemblyName "system.io.compression.filesystem"
[io.compression.zipfile]::CreateFromDirectory($zipStruct, $zipDestination)
# Compress-Archive doesn't work here because it includes the "zipStruct" folder: Compress-Archive -Path $zipStruct -DestinationPath $zipDestination
