DCS Livery Manager (DCSLM) is a Console/Terminal UI tool to help install, manage, and optimize liveries for DCS. Installing liveries from DCS User Files can be difficult at times as there is no standard way to package them! This tool makes that process as simple as possible by only taking the URL or ID of the livery and resolving the folder hierarchy within the archive to install it in to the correct aircraft directory in your DCS Saved Games folder. Using 7-Zip, DCSLM can handle any archive format, any kind of folders within (or lack of), and also livery packs.
You can also use DCSLM to optimize installed livery packs as it will find files that are the same between the different livery folders and change the description.lua files to point to the shared files, and then remove the unused ones. DCSLM can also check for updates to liveries from DCS User Files.
