Mod pages assume you know the vocabulary, and the vocabulary differs by game. This is the list we wish every file page linked to: the terms you meet on ModsDrop and on the mods’ own pages, in plain words, grouped by where you will see them. Bookmark it; we will add to it.

Files and formats

zip: the archive format BeamNG, the truck games and Farming Simulator read directly. Keep it zipped for those games.
7z, rar: other archive formats. Extract and repack to zip for games that read zips; extract for games that want folders.
.scs: Euro Truck Simulator 2 and American Truck Simulator’s native mod archive, a zip under another name.
SHA-256: a 64-character fingerprint of a file’s exact contents; shown on every file page here. Same hash, same file.
Lite version: a smaller build of a mod, usually with lower-resolution textures or fewer configurations.
Standalone: a mod that adds new content next to the game’s own rather than overwriting it. Opposite: replacement (or replace in GTA V); GTA’s word for standalone is add-on.
Dependency / requires: another mod that must be installed for this one to work.
Conversion / port: a mod moved from another game or game version. Needs the original author’s permission.
Reupload: someone else’s mod hosted without permission. Reportable.

BeamNG.drive

JBeam: the text format describing a vehicle’s physical structure, parts, weights and powertrain. The physics “recipe”.
Node, beam: a point with mass, and the spring connecting two of them. A car is thousands of each.
Soft-body: physics where the structure deforms node by node, rather than swapping damage models.
.pc: a part configuration, one complete set of part choices for a vehicle. A config pack is a set of them.
Skin: a texture painted over a car’s body, registered as a selectable part.
Parts mod: new parts (engines, kits, wheels) for an existing car, extending its parts tree.
Level: BeamNG’s word for a map.
User folder: where mods, settings and the cache live, under %LOCALAPPDATA%\BeamNG.drive\<version>; the launcher opens it.
Mod Manager, Repository: the in-game list of your mods, and the in-game browser of mods hosted by BeamNG.
Safe Mode, Clear Cache: launcher functions that start without mods, and delete the game’s derived data.
Unpacked: a mod kept as loose files instead of a zip, for editing.
Traffic: AI vehicles, each a full simulation; the main CPU cost.
BeamMP: the community multiplayer system. Servers set the mod list.
UI app: a HUD element written as web code; the mod type most affected by 0.40.
World Editor: the built-in tool for making and editing maps (PC only).

Euro Truck Simulator 2 and American Truck Simulator

Mod Manager: the per-profile list where mods are activated and ordered. Higher in the list has priority.
Load order: the sequence mods override each other in; the cause of most map-mod problems.
def: the definitions folder inside a mod, where vehicles, companies, cargo and paint jobs are declared.
manifest.sii: the mod’s description file, including the game version it declares.
Version warning: the Mod Manager’s note that a mod was made for a different game version. Advice, not a block, most of the time.
Owned trailer, company trailer: a trailer you buy and keep, versus one that comes with a freight-market job.
Cargo market, freight market: jobs for your own trailer, versus jobs that provide the trailer.
g_traffic: the traffic density setting, default 1.0.
FMOD, .bank: the audio engine since 1.37 and its sound file format; the reason old sound mods died.
Improved Material System: the interior lighting and material rendering introduced in 1.60 and extended truck by truck since.
Convoy: the official multiplayer for up to eight players with matching mods. TruckersMP: the community network with large servers and cosmetic-mods-only rules.
ProMods: the largest community map project for ETS2, requiring the official map expansions.
Profile: a career, with its own mod list, under Documents\...\profiles.
Open beta / public_beta: the Steam branch where the next version is tested before release.

Farming Simulator 25

ModHub: GIANTS’ curated official mod catalogue, in-game and on the web; the only source on consoles.
modDesc.xml: the mod’s description file, with its name, author, version and descVersion (the game generation it targets).
.i3d: GIANTS’ 3D model format.
GIANTS Editor: the official tool for maps and models; a new version per game generation.
Specialisation: a building block of vehicle behaviour in scripts (fillable, foldable, mower, and so on).
Mod selection screen: where mods are ticked per savegame, and where conflicts and dependencies are shown.
log.txt: the game’s log in Documents\My Games\FarmingSimulator2025.
Dedicated server: a standalone multiplayer server with a web interface for mods.
loadstring: a Lua function disabled in patch 1.24; script mods that used it broke.

GTA V and Assetto Corsa

Script Hook V, ScriptHookVDotNet: the frameworks that let .asi and .NET scripts run in GTA V.
OpenIV, mods folder: the archive editor and its feature that keeps edited game files separate from the originals.
.asi, .dll: native code plugins. Real programs; judge accordingly.
Legacy, Enhanced: GTA V’s two PC editions since March 2025, with separate mod support.
Content Manager: the community launcher for Assetto Corsa that installs and manages mods.
CSP (Custom Shaders Patch): the graphics and features extension most modern Assetto Corsa mods require.
Sol, Pure: weather and lighting systems built on CSP.
.kn5: Assetto Corsa’s model format.
EVO: Assetto Corsa EVO, the 2025 successor with its own, separate mod format.
