Copying Local Files and Folders to a USB Flash Drive

Use this standard operating system method to safely copy documents, pictures, and other files from your computer's local storage to a removable USB drive.

Copying files is ideal for transferring data to a new computer or creating a basic manual backup. Please note that this method only copies personal files; it does not back up your Windows operating system or installed applications.

1
Connect the USB drive

Insert your USB flash drive into an available USB port on your computer.

2
Locate your files

Open File Explorer and navigate to your main hard drive (usually the C: drive) or specifically to your Documents, Pictures, Music, Videos, and Downloads folders.

3
Copy the selected files

Highlight the files and folders you want to back up, right-click the selection, and choose 'Copy' (or press Ctrl+C on your keyboard).

4
Paste into the USB drive

Open the USB drive in File Explorer, right-click on an empty space within the window, and choose 'Paste' (or press Ctrl+V).

5
Safely eject the drive

Wait for the transfer to completely finish, then right-click the USB drive icon and select 'Eject' to safely remove it from your computer.

Frequently Asked Questions

Does copying files to a USB drive move them or duplicate them?

Using the 'Copy' and 'Paste' commands duplicates your files. The original files remain untouched on your computer's hard drive, while an exact copy is created on your USB flash drive.

Can I use my new email address to access my old OneDrive files?

Yes. When you add a new email alias to your existing Microsoft account, all your previously saved OneDrive files, subscriptions, and settings remain completely intact and accessible.

Why can't I copy a large file to my USB drive even though there is enough space?

If your USB drive is formatted using the FAT32 file system, it cannot hold an individual file larger than 4GB. You will need to backup existing data on the USB and format the drive to NTFS or exFAT to transfer larger files.

Does transferring my Documents folder to a USB drive back up my installed programs?

No. Copying standard user folders like Documents or Pictures only backs up your personal data. Installed applications and core Windows system files cannot be backed up this way and must be reinstalled from scratch on a new computer.
