| OS | Command | |----|---------| | Ubuntu / Debian | sudo apt update && sudo apt install megacmd | | Fedora / RHEL | sudo dnf install megacmd | | macOS (Homebrew) | brew install megacmd | | Windows | Download the MSI from https://mega.io/cmd and run the installer. Add the installation folder (e.g. C:\Program Files\MegaCMD) to your PATH. |

Relying solely on a cloud folder link is risky. Links break, accounts get suspended, and servers go down. For a true "High Quality" archive, you need the 3-2-1 Strategy:

rclone config
# Choose: n -> name: mega
# Storage type: 20 (Mega)
# No authentication needed for public links – just press Enter for all prompts.
# Save and quit.

One of the biggest mistakes enthusiasts make is re-compressing files to save space. While codecs like H.265 (HEVC) and AV1 offer fantastic efficiency, converting a high-bitrate file to a lower bitrate to fit on a smaller drive defeats the purpose of archiving "high quality."

The Rule of Thumb: If you must compress, do it once. Re-encoding a file multiple times introduces "generation loss," degrading the video or image quality permanently. For true archivists, storage is cheaper than quality loss.

  • MEGA uses end-to-end encryption for stored files; downloads occur over HTTPS and are decrypted client-side when the key is available.
  • Browser access typically gives downloadable, full-quality files (not reduced previews) if the shared link includes the decryption key and the uploader didn’t intentionally upload lower-quality versions.
  • MegaCMD stores a hidden state file (.mega-cp.state) in the target folder. If the process is killed, simply re‑run the same command; it will pick up where it left off.
