The fastest way depends on how many files you have and what you already own

Moving files to a new computer breaks down into three main routes: using an external drive or USB stick, transferring over your home network, or using cloud storage. Which one makes sense depends on the total size of your files, whether both computers are in the same room, and whether you want to move everything at once or gradually. If you have under 100 gigabytes and both computers are nearby, an external drive is usually fastest. If you have more than that, or if the computers are in different locations, a network transfer or cloud storage works better.

Before you start, decide what you actually need to move. Most people only need their documents, photos, videos, and email — not the programs themselves, which you can reinstall. Windows and Mac both have built-in tools to help, and the process usually takes between one and four hours depending on file size.

Key Takeaways

  • An external hard drive or USB stick works best for moving files under 100 gigabytes when both computers are in the same location.
  • Network transfer (using your home Wi-Fi) is faster for large files but requires both computers to be turned on and connected to the same network.
  • Cloud storage like Google Drive, OneDrive, or Dropbox lets you move files gradually and access them from anywhere, but uploading large amounts can take hours.
  • On Windows, use File Explorer to copy files to your external drive; on Mac, use Finder — both work the same way.
  • Email and browser bookmarks need separate steps because they store data differently than regular files.

Moving files with an external hard drive or USB stick

Plug the external drive into your old computer. On Windows, open File Explorer (the folder icon on your taskbar). On Mac, open Finder (the smiling face icon in your dock). Navigate to the folders you want to move — usually Documents, Pictures, Videos, and Downloads. Select all the files you need (use Ctrl+A on Windows or Command+A on Mac to select everything in that folder), then drag them to your external drive or right-click and choose "Copy".

Once the files finish copying (watch the progress bar), safely eject the drive. On Windows, right-click the drive in File Explorer and select "Eject". On Mac, drag the drive icon to the Trash or right-click it and select "Eject". Then unplug it, plug it into your new computer, and drag the files from the drive into the folders where you want them. This method works for files up to the size of your drive — a 1-terabyte external drive can hold roughly 200 hours of video or 250,000 photos.

Transferring files over your home network

If both computers are on the same Wi-Fi network and you have more than 500 gigabytes to move, a network transfer is often faster than using a physical drive. On Windows, open File Explorer, right-click the folder you want to share, select "Properties", go to the "Sharing" tab, and click "Share". Choose who can access it (usually just yourself), then note the network path shown on screen. On your new computer, open File Explorer, click "Network" in the left sidebar, find your old computer's name, and navigate to the shared folder.

On Mac, open System Settings, go to "General" then "Sharing", turn on "File Sharing", click the plus sign, and select the folder you want to share. On your new Mac, open Finder, click "Network" in the sidebar, find your old computer, and double-click the shared folder. Then drag files from the old computer to your new one. Network transfers work at your Wi-Fi speed — usually 20 to 100 megabytes per second, so a 100-gigabyte transfer takes roughly 15 to 80 minutes. Keep both computers plugged in and on the same network until the transfer finishes.

Using cloud storage to move files gradually

Cloud storage services like Google Drive, Microsoft OneDrive, or Dropbox let you upload files from your old computer and read them on your new one. This works well if you want to move files over several days, or if your computers are far apart. Sign up for the service (most offer 15 to 100 gigabytes free), install the app on your old computer, and drag your files into the cloud folder. The files upload in the background — speed depends on your internet connection, usually 5 to 50 megabytes per second.

Once the upload finishes, sign into the same account on your new computer, install the app, and the files read automatically. This method is slower than a physical drive for large amounts of data, but it gives you a backup copy and access from any device. If you have a lot of files, start the upload on your old computer the night before you want to use them on the new one.

Moving email and browser data

Email and bookmarks don't live in your regular Documents or Pictures folders — they need separate steps. For email, the easiest method is to sign into your email account (Gmail, Outlook, Yahoo, etc.) on your new computer using your username and password. Your emails read automatically. If you use a desktop email program like Outlook or Apple Mail, you may need to re-enter your account details, and the program will sync your old messages.

For browser bookmarks, open your browser on your old computer, look for a menu option called "Bookmarks" or "Favorites", and select "Export" or "Backup". Save the file to your external drive or cloud storage. On your new computer, open the same browser, go to Bookmarks, and select "Import" — then choose the file you saved. This works for Chrome, Firefox, Safari, and Edge.

What to do if the transfer stalls or fails

If a network transfer stops halfway through, check that both computers are still connected to Wi-Fi and that neither one has gone to sleep. On Windows, go to Settings > System > Power & Sleep and set the sleep timer to "Never" while you transfer. On Mac, go to System Settings > Lock Screen and turn off "Turn display off after" temporarily. If the transfer fails completely, try using an external drive instead — it's more reliable for very large amounts of data.

If you're moving files to a Mac from a Windows computer (or vice versa), the process is the same — both systems read external drives and network folders the same way. The only difference is that some older file types may not work perfectly on the new system, but documents, photos, and videos transfer without problems.

Checking that everything moved correctly

After the transfer finishes, open a few folders on your new computer and spot-check that the files are there and open properly. Try opening a document, a photo, and a video to make sure nothing got corrupted. If you moved email, send yourself a test message to confirm it arrives. If you moved bookmarks, click a few to make sure the links still work.

Once you've confirmed everything is there, you can delete the files from your old computer if you want to free up space — but keep them on your external drive or cloud storage for at least a week in case you need to recover something. After that, you can safely erase the external drive and reuse it.

Frequently Asked Questions

Can I move files while using my old computer?

Yes. You can copy files to an external drive or cloud storage while working normally. Network transfers are slower if you're using the old computer at the same time, so it's best to let them run overnight. Avoid moving the same file you're currently editing — close it first, move it, then open it on the new computer.

What if my new computer already has files in the Documents folder?

When you drag files from your external drive, you can choose to merge them with existing files or replace them. If you want to keep both sets, create a new folder on your new computer (like "Old Computer Files") and move your transferred files there instead. This keeps everything organized and prevents accidental overwrites.

Do I need to reinstall my programs on the new computer?

Yes. Programs don't transfer between computers — you need to install them fresh on your new machine. Your files (documents, photos, videos) move fine, but the actual software needs to be installed from the original source or app store. Your licenses and settings usually transfer if you sign into the same account.

How long does a large file transfer usually take?

An external drive transfer of 500 gigabytes takes roughly 2 to 4 hours. A network transfer of the same amount takes 1 to 2 hours. Cloud storage uploads of 500 gigabytes can take 10 to 20 hours depending on your internet speed. Start with the method that fits your timeline and patience.

Is it safe to move files to cloud storage?

Cloud storage is find for most personal files — Google, Microsoft, and Dropbox all encrypt your data. If you have sensitive documents, read the privacy policy of whichever service you choose. For extra security, you can move files to an external drive instead and keep it in a safe place, though you won't be able to access them from other devices.
