Library, disk space and loadouts
The library
Everything REDdeck knows is kept in plain files in the library folder, %USERPROFILE%\REDdeck by default. Open library folder in the Mods view’s ... menu opens it.
| Folder or file | Contents |
|---|---|
library/<mod>/ |
One folder per mod version, laid out exactly as it deploys, with a mod.json beside the files: name, version, kinds, where it came from, Nexus data |
library.json |
The order of your mods (first wins) and the game folder |
downloads/ |
The original downloads, kept so a mod can be added again. Safe to delete |
backup/ |
Files a deploy moved out of the way. Undo deploy puts them back |
loadouts/ |
Your saved loadouts |
The game folder also gets a manifest of what REDdeck deployed, which Undo deploy reads.
Because the library is plain folders and JSON files, you can look inside it with File Explorer, back it up by copying it, and an AI assistant can read it to answer questions about your mods.
Moving the library
Set reddeck.libraryPath to the folder you want. Choose a folder on the same drive as the game, so deploy can use hardlinks and your mods don’t take up space twice. See Settings and commands.
Disk space
REDdeck shows sizes everywhere: next to every mod, folder and file in the Mods view, in the REDdeck page’s Size column, and in the page’s footer, for example Disk: 160 MB in mods, 1.9 MB in kept downloads.
| What | Uses space? | Safe to delete? |
|---|---|---|
| Mods in the library | Yes, once | Remove mods you no longer want |
| Deployed files in the game | No extra space with hardlinks (library on the game’s drive). A second copy otherwise | Use Undo deploy, never delete them by hand |
| Kept downloads | Yes | Yes. The footer link opens the folder |
| Deploy backups | Yes, usually little | Only if you’ll never need Undo deploy to restore them |
| Old versions of mods | Yes | Switch to the version you want, then remove the others |
Largest first on the REDdeck page sorts every mod by size, which is the quickest way to find what’s using the most space.
Loadouts
A loadout is a saved list: which mods are on and in what order, plus the game version. Use loadouts to switch between setups, such as a story playthrough and a photo-mode setup, or to share your setup with a friend.
- Save loadout writes the current list to a file in the library’s
loadoutsfolder. - Load loadout applies one: mods in it go on, mods not in it go off, and any mods it names that your library doesn’t have are listed for you. Deploy afterwards.
Loadouts are plain JSON files, fine to share. Someone loading yours needs the same mods in their library.
