Resumable Downloads

What is the Resumable Downloads feature?

Traditionally, browser downloads are handled entirely by your browser's default manager. If your internet flickers or our servers hiccup, the download often cancels, forcing you to start from scratch.

Our new Resumable Download system utilises the modern File System API, which allows your browser to stream the file data directly to a designated file on your drive.

Key Benefits

• Automatic Retry: If your connection drops, the system will automatically attempt to pick up exactly where it left off.
• Stable Large Downloads: Mods that weigh multiple gigabytes are downloaded with a reduced risk of corruption caused by interrupted packets.
• No Expiry: Traditional download links will expire after a while. Resumable Downloads will automatically fetch a new link and carry on downloading if this happens.

Frequently Asked Questions (FAQ)

How does it work?

When you start downloading a file over 500MB, you will be offered a choice between "Standard download" or "Resumable download". The resumable option will then ask you to pick a destination for the file (we recommend avoiding protected folders such as C:\Program Files). The file will then be streamed directly to the selected location, and you'll see a progress bar to keep track of how much is left to download.

Does this work on all browsers?

Currently, this feature is best supported on Chromium-based browsers (Chrome, Edge, Opera). Firefox support is limited as they implement the API differently.

Will this be available for Premium users?

Yes! We want to get new features in front of all users as soon as possible, so we have initially released this feature for free users only. In future, we will be exploring the best way to add it into the Premium download flow, too.

What happens if I close the tab?

If the tab is closed, the download will pause. You can attempt to resume an existing download by restarting the download and picking the "Resumable download" option again.

Is this faster than normal downloads?

While this doesn't affect your download speed limit directly, it will be "faster" in the long run, as you won't need to re-download the whole file if your connection is interrupted.

Why can't I see the Resumable download option?

This feature is currently limited to free user accounts downloading files over 500MB. The option may not appear if your browser doesn't support the File System API or if your browser addons/privacy settings are blocking scripts required for the feature to operate.

Can I recover an interrupted download?

In most cases, yes. Downloads can be resumed by restarting the download process. However, if you've moved or deleted the temporary file, you may see the message shown below.

If you still have the file for the previous attempt, you can use "Recover download" to select it and continue where you left off. If you no longer have the temporary file, you can restart the download from the beginning.

Why am I seeing an error about insufficient disk space?

Due to a quirk in how the File System API works, resuming a download first creates a copy of the partial file you're resuming from. This means that if you've previously downloaded 5GB of the file before resuming, it will temporarily take up 10GB until the download completes. To avoid this error message, please ensure you have enough hard drive space available or move the temporary file to a drive with larger storage and recover the download using the option above.

Why does the downloaded file appear to be corrupted?

This can occur if you try to open the file before the download has fully finalised. Please verify the download is complete before interacting with the file.
