Moving huge files (games, movies, backups) is tricky.
One mistake — and hours of downloads can vanish.
Here’s how to move large files safely without losing anything.
✅ 1. Always use copy first, then delete
-
First copy the file to new location
-
Only delete the original after verifying the copy is complete
✅ Copy protects against accidental interruptions.
✅ 2. Use fast drives and cables
-
Use USB 3.0 or better external drives
-
Use SSDs for internal moves if possible
✅ Faster transfers = less chance of corruption.
✅ 3. Pause antivirus temporarily
Some antivirus programs scan large files during copy → slows or breaks the process.
✅ Disable real-time protection only during large copy/move jobs (trusted files only).
✅ 4. Use robust copy tools
-
TeraCopy – Faster, error-checked copying
-
FastCopy – Lightweight, stable for huge transfers
✅ These tools retry failed transfers automatically.
✅ 5. Avoid Wi-Fi file transfers
If possible:
-
Use wired LAN
-
Or transfer directly via external drives
✅ Wi-Fi transfers are slower, risk disconnections.
Key points to remember
-
Copy first → verify → delete original
-
Use fast drives and connections
-
Temporary antivirus disable = smoother copying
-
Tools like TeraCopy = safer large moves
-
Wired transfers beat Wi-Fi every time
