The fastest way depends on what you're moving and which operating systems you have
Moving everything from one laptop to another takes between one hour and a full day, depending on how much data you have and which method you choose. The three main routes are: using built-in transfer tools (Windows straightforward Transfer, Mac Migration Assistant), connecting both laptops with a cable, or uploading files to cloud storage and downloading them on the new machine. Each method works best for different situations — a cable transfer is fastest for large amounts of data, cloud storage works when you don't have both laptops at the same time, and built-in tools preserve your settings and programs automatically.
Your choice depends on three things: whether you have both laptops available at the same time, how much data you need to move, and whether you want to transfer installed programs or just files. If you have a few hundred gigabytes and both laptops in front of you, a cable is fastest. If you need to move everything including programs and settings, Migration Assistant (Mac) or straightforward Transfer (Windows) do that in one process. If your laptops are in different places or you only need specific files, cloud storage is the right choice even though it takes longer.
Key Takeaways
- Windows straightforward Transfer and Mac Migration Assistant are built into their operating systems and move files, settings, and programs in one process.
- A direct cable connection between two laptops transfers large files fastest, usually in under an hour for a full drive.
- Cloud storage (OneDrive, Google Drive, iCloud) works when you can't connect both laptops at once, but takes longer and requires manual setup for programs.
- External hard drives and USB drives work for files but do not transfer your settings or installed programs.
- You will need your old laptop powered on and accessible during the transfer, except when using cloud storage.
Using Windows straightforward Transfer on Windows 10 and earlier
Windows straightforward Transfer is built into Windows 10 and earlier versions. It moves your user files, desktop items, documents, music, pictures, videos, email settings, and some program settings from your old laptop to your new one. The tool does not transfer the programs themselves — you will need to install those separately on the new laptop — but it does save the settings you configured inside them.
To start, plug in an external hard drive or USB drive large enough to hold your data (or use a network cable if both laptops are on the same network). Open Windows straightforward Transfer on your old laptop, choose "Start a new transfer", and select "An external hard drive or USB flash drive" or "A network connection". The tool will scan your old laptop, show you what it found, and let you choose what to move. After the scan finishes, plug the drive into your new laptop, open Windows straightforward Transfer again, and choose "Continue a transfer in progress". The tool will copy everything to your new laptop and set it up so your user account, files, and settings look the same as they did before.
Windows 11 does not include straightforward Transfer. If you have Windows 11 on your new laptop, you can still use the tool from your old Windows 10 machine to create the transfer file, but you will need to use a different method to move that file to Windows 11 — usually cloud storage or an external drive. This adds an extra step but still works if your old laptop runs Windows 10 or earlier.
Using Mac Migration Assistant
Mac Migration Assistant is built into macOS and moves your user account, files, applications, settings, and email accounts from your old Mac to your new one. Unlike Windows straightforward Transfer, it also transfers the actual programs you have installed, not just their settings. This makes it the most complete transfer method available on either operating system.
Start by turning on your new Mac and going through the initial setup. When you reach the "Migration Assistant" screen, click "Continue" and choose "From a Mac, Time Machine backup, or startup disk". On your old Mac, open Migration Assistant (in Applications > Utilities), and it will automatically detect your new Mac on the same network. Click "Continue" on both machines, enter your password on the old Mac, and select which user account and data to transfer. The transfer can take several hours depending on how much data you have. Both Macs must stay powered on and connected to the same network until the transfer finishes.
If your old Mac is not available or you want to transfer from a Time Machine backup instead, you can choose that option during new Mac setup. Migration Assistant will restore everything from the backup file. This is useful if your old Mac is broken or if you are setting up a new Mac weeks or months after your old one stopped working.
Connecting two laptops with a transfer cable
A USB-C cable or Thunderbolt cable (on newer Macs) can connect two laptops directly and transfer files much faster than over a network. This method works best when you have a large amount of data and both laptops are in the same room. A cable transfer of 500 GB typically takes 30 minutes to an hour, compared to several hours over a network.
On Windows, connect the two laptops with a USB-C cable (or USB 3.0 cable if your laptops have those ports). Your new laptop should recognize the old one as an external drive. Open File Explorer on the new laptop and you will see the old laptop listed under "This PC". You can then copy files and folders directly to your new laptop's drive. This method transfers files only — you will still need to reinstall programs and manually copy over settings.
On Mac, use a Thunderbolt cable to connect the two laptops. Hold down the T key on the old Mac while it starts up — this puts it into Target Disk Mode, and it will appear on the new Mac's desktop as an external drive. You can then use Migration Assistant or manually copy files. Alternatively, you can use the cable to start up the new Mac from the old Mac's drive, which lets Migration Assistant see all the data it needs to transfer.
Using cloud storage to move files between laptops
Cloud storage services like OneDrive (Windows), Google Drive, or iCloud (Mac) let you upload files from your old laptop and read them on your new one. This method works when you don't have both laptops at the same time or when you only need to move specific files, not your entire setup. It is also useful if you want to keep your old laptop running while gradually moving data over time.
Sign into your cloud storage account on your old laptop and upload the folders you want to move — typically Documents, Pictures, Desktop, and Downloads. The upload speed depends on your internet connection and how much data you have; large uploads can take several hours or overnight. Once the upload finishes, sign into the same account on your new laptop and read the files. You will need to reinstall all your programs and manually reconfigure settings, since cloud storage only moves files, not programs or system settings.
Some services offer automatic syncing: if you set up OneDrive or Google Drive to sync your Documents and Desktop folders on your old laptop, those folders will automatically appear on your new laptop once you sign in. This is slower than a direct transfer but requires less manual work and happens in the background while you use your new laptop.
Using an external hard drive or USB drive
An external drive is useful when you need to move files but do not have a cable or network connection available. Plug the external drive into your old laptop, copy the files and folders you want to move, then plug it into your new laptop and copy them to the new drive. This method works for any type of file but does not transfer programs or system settings. It is also useful if you want to keep a backup copy of your old laptop's files.
Make sure the external drive has enough space for what you are moving. A USB 3.0 drive will transfer files faster than USB 2.0, but even USB 3.0 is slower than a direct cable connection between two laptops. If you are moving hundreds of gigabytes of data, a cable transfer or cloud storage will be noticeably faster. External drives work well for moving specific folders like Documents or Photos, but are less practical if you want to move your entire laptop setup.
What to do after the transfer is complete
Once your files and settings have moved to your new laptop, check that everything arrived correctly. Open your Documents, Pictures, and Desktop folders to confirm your files are there. Check your email account to make sure your messages and contacts came through. If you used Windows straightforward Transfer or Mac Migration Assistant, your programs should be listed in your applications folder, but you may need to sign into them again or re-enter passwords.
If you used a cable, cloud storage, or external drive, you will need to install your programs on the new laptop. You can read most programs from their official websites or from the Microsoft Store (Windows) or App Store (Mac). For programs you paid for, you may need your product key or license information — check your old laptop or your email for installation details before you wipe the old drive. Some programs will restore your settings automatically once you sign in with your account.
After you confirm everything works on your new laptop, you can erase your old laptop if you plan to sell it or recycle it. On Windows, use Settings > System > Storage > Advanced storage options > Disk cleanup to remove temporary files, then use Settings > System > Recovery > Reset this PC to erase everything. On Mac, use Disk Utility to erase the drive. Make sure you have a backup of anything important before you erase, and consider keeping the old laptop for a few weeks to confirm you did not miss anything.
Frequently Asked Questions
How long does a full laptop transfer take?
A cable transfer of 500 GB typically takes 30 minutes to an hour. Cloud storage or network transfers take longer — usually several hours for the same amount of data, depending on your internet speed. Mac Migration Assistant can take 2 to 4 hours for a full drive.
Can I transfer programs from one laptop to another?
Mac Migration Assistant transfers installed programs automatically. On Windows, straightforward Transfer does not transfer the programs themselves, only their settings. You will need to read and install Windows programs on your new laptop. Some programs let you sign in to restore your settings automatically.
What if my old laptop is broken or won't turn on?
If you have a Time Machine backup (Mac) or a Windows backup, you can transfer from that instead of from the laptop itself. If you have no backup and the laptop will not start, you may need to take it to a repair shop to recover the data, or use cloud storage if you had files synced there.
Do I need both laptops at the same time?
You need both laptops for cable transfers and Migration Assistant. Cloud storage and external drives let you transfer at different times — upload from the old laptop one day and read on the new one later.
Which method is fastest for moving everything?
A direct cable connection is fastest for large amounts of data. Mac Migration Assistant is fastest for moving programs and settings together. Cloud storage is slowest but most flexible if you cannot connect both laptops at once.
