Downloaded a big file.
Tried to open it.
And boom — “Corrupt file” error.
Here’s how to try saving or repairing a broken download.
✅ 1. Try re-downloading first
-
Corruption often happens during the download itself (network errors, disk errors)
-
Re-download from the same site — or a mirror if available
✅ Use a wired connection to prevent partial downloads.
✅ 2. Use file repair tools (for archives)
If it’s a ZIP, RAR, or 7Z file:
-
Use WinRAR → Tools → Repair Archive
-
Use 7-Zip → Try to extract broken files anyway
✅ Partial recovery is often possible.
✅ 3. Try opening with alternative apps
Sometimes one app says “corrupt” but another reads fine.
Try:
-
OpenOffice (for damaged DOC, XLS files)
-
VLC Player (for broken video files)
-
7-Zip (for damaged archives)
✅ 4. Use hash checks
If the site provided an MD5, SHA1, or SHA256 hash:
-
Use HashTab or WinMD5 to verify file integrity
-
Mismatched hash = download was corrupted
✅ Saves you hours wondering if it’s your PC’s fault.
✅ 5. Use resume-enabled downloads
Next time:
-
Use Free Download Manager (FDM) or Internet Download Manager (IDM)
-
Resuming cuts corruption risk by avoiding full restart.
Key points to remember
-
Always try re-downloading first
-
Repair damaged archives with WinRAR or 7-Zip
-
Alternative apps might open corrupted files
-
Verify files using hash checks
-
Use download managers for safer large downloads
