Moving files between your own devices

Moving a file between two machines you own should be the easy case, and it is often the most annoying: the phone and the laptop are on different platforms, the desktop is in another room, and emailing yourself has become a genuine workflow for millions of people.

Here is what to use, ordered by the situation you are actually in.

Both devices in the same room

Same ecosystem: AirDrop between Apple devices, Quick Share between Android and Windows. Both keep the original file, need no account, and are the fastest option available. Use them when they work.

Mixed platforms — an iPhone and a Windows laptop, an Android and a Mac — is where the ecosystem tools stop, and it is the most common real situation. A cable works and requires the right adapter and, on Windows, occasionally a driver. A transfer link in the browser works on everything.

For phone-to-laptop specifically, the fastest browser route is a QR code: upload from the phone, show the code, point the laptop's camera at it. No typing a URL, no emailing yourself.

Different places

Home desktop to office laptop, or your machine to a machine you will be using later.

A transfer link is the low-commitment answer: upload, and open the link wherever you land. Nothing to install on the other end, which matters when the other end is a machine you do not control.

Cloud sync is better when it is continuous. If the same working folder needs to exist on both machines every day, that is what sync is for, and no amount of manual transferring replaces it.

The distinction is whether this is a move or an ongoing arrangement. Moves suit links; arrangements suit sync.

A machine you do not control

A hotel business centre, a client's workstation, a shared library computer.

A browser-based transfer is the right tool because it leaves nothing behind: no client installed, no account signed into, no sync folder quietly downloading your entire drive onto someone else's machine. That last one happens more than you would think.

Two habits: sign out of anything you signed into, and clear the download afterwards. If the file is sensitive, use a short expiry so the link is dead by the time you have left the building.

Moving to a new computer

For a whole-machine migration, use the migration tool — Windows Backup or a direct transfer, Apple's Migration Assistant — rather than moving files by hand. They carry settings and application data that a file copy does not.

File transfer is for the gap: the handful of things you need on the new machine before the migration finishes, or the things that live outside the user folder and get missed.

Very large amounts of data

An external drive is still the fastest way to move a terabyte between two machines in the same building. USB 3 comfortably exceeds any consumer internet connection, and it does not care about your upload speed.

Over a network and at that size, a transfer service starts costing hours. Do the arithmetic before committing: at a real 20 Mbps upload, 1 TB is more than five days. See how long an upload takes.

Things worth avoiding

• Emailing yourself. Attachment limits apply to you as much as anyone, and it clutters a mailbox you have to search later.
• A messaging app "just to move a photo". It will re-compress it. See sharing photos without losing quality.
• A USB stick between machines you do not both trust. Removable media is still a genuine malware route in mixed environments.
• Installing a sync client on a borrowed machine. The convenience lasts minutes; the account signed in on someone else's computer lasts until you remember.

Quick reference

• Same room, same ecosystem: AirDrop or Quick Share.
• Same room, mixed platforms: transfer link with a QR code.
• Different places, one-off: transfer link.
• Different places, every day: cloud sync.
• Borrowed machine: transfer link, short expiry, sign out.
• A terabyte, same building: an external drive.
