Quick Fix Summary
Stuck on a “Failed” download in the MEGA app? Open version 5.10.8 or newer, tap the three-line menu in the top left, then hit **Downloads**. Pick the file marked “Failed,” tap the circular arrow icon to **Resume**. No joy? Restart MEGAAsync from the system tray or clear the app cache under **Settings > Advanced > Clear Cache**. Windows users can also right-click the M icon in the taskbar and pick **Resume all transfers**.
What's going on with the download?
The download is paused and marked “Failed” but the partial file usually remains on your list.
When a MEGA desktop download (current stable build 5.10.8) suddenly stops, the app slaps a “Failed” label on it yet keeps the half-downloaded file around. Network hiccups, system sleep, or even overzealous antivirus scans can trigger this. The transfer engine freezes automatically, but the file lingers so you can pick up where you left off.
How do I actually resume the download?
Open the MEGA app, go to Downloads, pick the failed file, and click the circular arrow icon.
Here’s the step-by-step:
1. **Fire up the MEGA app**
Launch it from your desktop, Start menu, or—on Windows 11—dig into **All apps > MEGA**. Mac users should look in **Applications > MEGA.app**.
2. **Head to the Downloads list**
Hit the three-line menu (☰) in the top-left corner, then choose **Downloads**. You’ll see both active and failed transfers.
3. **Find the culprit**
Scroll to the file tagged “Failed” or sporting a red warning icon. Hover over it to read the exact error.
4. **Hit Resume**
In the right column, click the circular arrow labeled **Resume**. If the button’s grayed out, the server probably nuked the partial file.
5. **Wake up the background service**
If the app’s minimized, right-click the **M** icon in the Windows taskbar notification area or the macOS menu bar. Pick **Resume all transfers**. That wakes up MEGAAsync and restarts the paused downloads.
6. **Watch it restart**
A spinning circle next to the file name means it’s back in business. Speed and progress show up in the same list.
What if the Resume button does nothing?
Restart MEGAAsync, clear the cache, or switch to the web client as a fallback.
Try these in order:
- **Kill and restart MEGAAsync (Windows only)**
Press **Ctrl + Shift + Esc**, jump to the **Processes** tab, locate **MEGAAsync.exe**, right-click it, and choose **End task**. Reopen the MEGA app—it’ll restart the service automatically.
- **Clear the app cache**
Inside the MEGA app, go to **Settings > Advanced > Clear Cache**. That tosses any temporary blocks or corrupted queue files. Restart the app afterward.
- **Fall back to the web client**
Open https://mega.io in Chrome or Edge, sign in, and grab the file from your cloud drive. The web version retries differently and often skirts local app gremlins.
Can I stop this from happening again?
Yes—keep the app updated, avoid sleep during transfers, pause before shutdown, whitelist MEGA in your firewall, and use Ethernet for big files.
A few habits go a long way:
- **Turn on auto-updates**
MEGA rolls out security and stability patches every few months. In the app, hit **Settings > About > Check for updates** once a month to stay current.
- **Stop your PC from sleeping mid-transfer**
Windows and macOS both freeze network activity when they snooze. On Windows, open **Control Panel > Power Options > Choose what the power buttons do**. On macOS, head to **System Preferences > Battery > Power Adapter** and check **Prevent computer from sleeping when display is off**.
- **Pause before you shut down**
Always click the pause icon (⏸) in the MEGA app or system tray before powering off. That keeps the app from labeling files as failed when the OS yanks the network rug out from under it.
- **Let MEGA through your firewall**
In Windows Defender Firewall, go to **Settings > Update & Security > Windows Security > Firewall & network protection > Allow an app through firewall**. Add **MEGAAsync.exe** and tick both Private and Public networks.
- **Plug in for big downloads**
Wi-Fi dropouts are the #1 reason transfers tank. Anything over 1 GB? Hook up an Ethernet cable or park closer to the router.
