Downloads

Every download task (game installation, mods, modpacks, updates) shows up in the Downloads (Download Center), with parallel execution, pausing, and live progress.

Interface

Click Downloads in the sidebar to open it:

Live progress: each task shows its speed, progress bar, and completed size against total size
Parallel tasks: multiple tasks download at once without blocking each other
Cancel a task: cancel directly from the task card

Download acceleration

The Launcher (Launcher)ships with several acceleration mechanisms (Settings → Download settings (Download settings)):

Setting	What it does
Download threads	Concurrent connections per task, 64 by default. Lower it on a poor network
File chunk threads	Splits large files into chunks and downloads them in parallel
Download timeout	Timeout for a single request, in seconds
HTTP/3	Experimental; enables HTTP/3 transport for CDNs that support it
Automatic download source selection	Automatically speed-tests and switches between official sources and QML mirrors

When downloads are slow or failing, try this first: turn on the matching automatic-selection switch. For the mirror architecture and path mapping, see Download mirrors.

Naming resource files

You can customize the naming format for downloaded resources such as mods (Settings → Download settings → File naming). Supported combinations include:

localized-name-version / version-localized-name / localized-name / original-name, and more

Pick whichever matches the way you organize your mod folder.
