The fastest way to move files between drives

Open File Explorer, find the files or folder you want to move, right-click it, and select Cut. Navigate to the destination drive or folder, right-click the empty space, and select Paste. The files move from the original location to the new one — they don't stay in both places.

This method works whether you're moving to an external drive, a second internal drive, or a network location. The time it takes depends on file size and your drive speed, but Windows shows a progress window so you can see what's happening.

If you want to keep a copy in the original location instead of moving, use Copy instead of Cut. You'll then have the files in both places, which uses more storage space but leaves your originals untouched.

Key Takeaways

  • Cut and Paste moves files from one drive to another; Copy and Paste leaves them in both places.
  • You can move entire folders at once, and Windows will move everything inside them without asking about each file.
  • Moving files between drives on the same computer is much faster than copying because the data doesn't have to be written twice.
  • If the move fails partway through, check that your destination drive has enough free space and isn't write-protected.

Using drag-and-drop to move files between drives

You can also drag files from one drive to another in File Explorer. Click and hold a file, drag it to the destination folder in the left sidebar or in another File Explorer window, then release. Windows moves the file if you're dragging between different drives.

This method is slower than Cut and Paste for large files because it's easier to accidentally copy instead of move. To be sure you're moving and not copying, hold the Shift key while dragging. The cursor will show a small arrow indicating the file is moving rather than copying.

Drag-and-drop works best for moving a few files at a time. For moving dozens of files or entire folders, Cut and Paste is more reliable because you can see exactly what you're moving before you confirm.

Moving files to an external drive

Connect the external drive to your computer via USB. It will appear in File Explorer under This PC with a drive letter (usually D:, E:, or higher). Use the same Cut and Paste method: right-click the files you want to move, select Cut, navigate to the external drive, and select Paste.

Moving to an external drive takes longer than moving between internal drives because USB transfers are slower. A 10 GB folder might take 5 to 15 minutes depending on your USB version and drive speed. Don't unplug the drive until the progress window closes and you see the files in the destination folder.

If you're moving large amounts of data regularly, check your external drive's speed rating. USB 3.0 drives are significantly faster than USB 2.0, and newer USB 3.1 or Thunderbolt drives are faster still.

What to do if the move fails or gets stuck

If a move operation stops or shows an error, the most common cause is insufficient space on the destination drive. Right-click the destination drive in File Explorer, select Properties, and check the free space shown at the bottom. You need at least as much free space as the files you're moving.

If the destination drive shows plenty of space but the move still fails, the drive might be write-protected. External drives sometimes have a physical lock switch on the USB connector — check for a small sliding switch and make sure it's in the unlocked position. If there's no physical switch, right-click the drive in File Explorer, select Properties, and check whether Read-only is checked under Attributes. If it is, uncheck it and try again.

For very large files (over 4 GB), check the file system of your destination drive. If it's formatted as FAT32, it cannot hold files larger than 4 GB. You'll need to reformat the drive as NTFS or exFAT, which will erase everything on it. Back up any files on that drive first, then right-click it, select Format, and choose NTFS or exFAT from the file system menu.

Moving your user files to a second internal drive

If you've added a second internal drive to your computer and want to move your Documents, Pictures, Downloads, or other user folders there, you can change where Windows stores them. Right-click the folder you want to move (for example, Documents in File Explorer), select Properties, click the Location tab, and click Move. Select the destination folder on your second drive and confirm.

Windows will move the folder and all its contents, then redirect the original location to point to the new one. Any program that saves to Documents will now save to your second drive instead. This is useful if your main drive is running low on space and you want to keep your user files on a larger or faster secondary drive.

Don't move your entire user profile folder (C:\Users\YourName) this way — that can cause Windows to stop working correctly. Stick to moving individual folders like Documents, Pictures, Downloads, and Desktop.

Checking drive space before and after moving

Before moving large files, check how much space you have on both drives. Open File Explorer, right-click each drive under This PC, and select Properties. The window shows total capacity, used space, and free space. Make sure the destination drive has more free space than the files you're moving.

After the move completes, the source drive should show more free space (because the files are no longer there) and the destination drive should show less free space (because the files are now there). If the source drive's free space didn't increase, the move may not have completed. Check the destination drive to confirm the files arrived before deleting anything from the source.

Frequently Asked Questions

Does moving files delete them from the original drive?

Yes. When you cut and paste, the files are removed from the original location and placed in the new one. They exist in only one place. If you want to keep them in both places, use copy instead of cut.

Can I move files while they're open in a program?

Usually not. If a file is open in Word, Photoshop, or another program, Windows locks it and won't let you move it. Close the file in the program first, then move it. Some programs lock entire folders, so close the program completely if moving a single file doesn't work.

What's the difference between moving and copying?

Moving (cut and paste) removes files from the original location and puts them in the new one. Copying leaves them in both places. Moving is faster and saves space; copying is safer if you want to keep a backup.

How long does it take to move files to an external drive?

Speed depends on file size and USB version. USB 3.0 transfers about 100 MB per second, so a 10 GB folder takes roughly 100 seconds. USB 2.0 is much slower at about 30 MB per second. Larger files and older drives take proportionally longer.

What if I accidentally moved files to the wrong location?

Cut them again from the wrong location and paste them in the correct one. You can move files as many times as needed. If you've already closed File Explorer, you can still find and move them — they're just in a different folder than you intended.
