Where Does Arma 3 Store Workshop Mods?
Arma 3 mods download as numbered Workshop folders plus launcher presets. The numbers are Steam's, not the mod's name.
Last updated
Arma modding runs through Steam Workshop folders named by Workshop ID number, which baffles everyone exactly once. Each subscription becomes a numbered folder under the Workshop content path for Arma 3. The official launcher translates those numbers into mod names and builds loadable presets from them.
Manual mods go elsewhere and load with startup parameters, but Workshop plus launcher presets cover nearly every unit. Mod count directly drives join times and desync risk, so trim ruthlessly before operations. Server keys in the mod folders decide which servers accept you, another reason to keep sets exact.

Numbered per mod folders named by Workshop ID. Manage through launcher presets, never by renaming numbers. Pair with matching server keys for multiplayer.
Frequently asked questions
My Workshop folder is all numbers. Which mod is which?
Read the numeric folder's meta file to identify it, since Steam names folders by Workshop ID. The launcher shows friendly names for the same folders. Never rename the numbers by hand or updates detach.
How do groups keep mod sets in sync?
Save the mod set as a launcher preset per unit or mission. Presets record exact versions, so the whole group loads identically. HTML preset files share the list without sharing files.
