A memory stick, also called a USB flash drive or USB drive, is one of the easiest ways to move files from one computer to another. You can use it to store documents, photos, videos, music, PDFs, folders, and other files without needing an internet connection.
Adding files to a USB drive is pretty straightforward, even if you have never done it before. You simply connect the drive to your computer, open it in File Explorer, find the files you want to move or copy, and transfer them to the USB drive. The exact process can vary slightly depending on your version of Windows, but the basic steps are almost the same.
Before you start, make sure the USB drive has enough free storage space for the files you want to add.
Also, if the files are important, it is usually better to copy them instead of moving them. That way, the original files remain safely on your computer.
Add Files to a Memory Stick or USB Drive
To add files to a USB drive:
- Plug the USB drive into an available USB port on your computer.
- Open File Explorer and select the USB drive under This PC.
- Open another File Explorer window and locate the files or folders you want to add.
- Select the files, right-click them, and choose Copy.
- Open your USB drive, right-click an empty area, and select Paste.
- Wait for the file transfer to finish, then safely eject the USB drive before removing it.
The following steps walk you through the entire process from connecting the drive to safely removing it.
Step 1: Connect the USB Drive to Your Computer
Start by connecting your USB flash drive to an available USB port on your computer. On a desktop PC, you will normally find USB ports on the front or back of the computer. On a laptop, the ports are usually located along the sides.
Insert the USB drive carefully into the port. If your computer has both USB-A and USB-C ports, make sure the connector matches the port. Do not force the drive into the slot.
After a few seconds, Windows should recognize the USB drive automatically. You may see a notification telling you that the device is ready to use. If nothing appears on your screen, that does not necessarily mean there is a problem. You can check whether Windows detected it in the next step.
Step 2: Open File Explorer
Now open File Explorer. The quickest way to do this is to press Windows + E on your keyboard. You can also select the File Explorer icon from the taskbar or open it from the Start menu.
Once File Explorer opens, look at the left side of the window and select This PC. This section displays the storage devices connected to your computer.
Under Devices and drives, you should see your computer’s internal storage along with the connected USB drive. The USB drive may appear with a name such as USB Drive, Removable Disk, or a custom name assigned to the device.
Step 3: Identify and Open the USB Drive
Find your USB drive under Devices and drives. Windows normally assigns the drive a letter, such as E:, F:, or G:. The exact letter depends on the other storage devices connected to your computer.
Double-click the USB drive to open it. You should see its current contents inside the File Explorer window.
If the drive is new or has recently been formatted, it may be completely empty. That is perfectly normal. If you already have files stored on it, you will see them here.
Take a moment to check the available storage space shown for the drive. If you are planning to copy a large video collection or several folders, make sure the USB drive has enough room.
Step 4: Locate the Files You Want to Add
Next, find the files or folders that you want to put on the USB drive. You can keep the USB drive open and use another File Explorer window to find your files.
For example, if you want to copy photos, you might go to This PC > Pictures. For documents, you might check Documents or Downloads. If you saved the files somewhere else, simply navigate to that location.
You do not have to copy files one at a time. If several files are located in the same folder, you can select multiple items at once. Hold the Ctrl key while selecting individual files, or press Ctrl + A to select everything in the current folder.
Be careful with Ctrl + A, though. It selects every item in that folder, which may include files you did not intend to copy.
Step 5: Copy the Files
After selecting the files, right-click one of the highlighted files and choose Copy. You can also use the keyboard shortcut Ctrl + C.
When you choose Copy, Windows does not immediately place the files on the USB drive. Instead, it temporarily prepares a copy of the selected files so you can paste them somewhere else.
This is an important distinction. Copying does not delete the original files from your computer. That makes it the recommended option when you simply want another copy of your files on the memory stick.
Step 6: Paste the Files Into the USB Drive
Return to the File Explorer window showing your USB drive. Open the folder where you want to store the files. If you want them in the main USB drive location, simply stay there.
Right-click an empty area inside the window and select Paste. Alternatively, press Ctrl + V on your keyboard.
Windows will begin transferring the files to the USB drive. A file transfer window may appear, showing the progress. The amount of time required depends on the size and number of files and the speed of your USB drive.
Do not unplug the USB drive while the transfer is still running. Removing it during a file transfer could result in corrupted or incomplete files.
Step 7: Check That the Files Were Added
Once the transfer finishes, check the USB drive to make sure the files are actually there. You should see the copied files in the location where you pasted them.
For extra reassurance, open one of the transferred files directly from the USB drive. For example, you can open a photo, document, or PDF to confirm that it transferred correctly.
If you copied a large number of files, you can also compare the file count or check the USB drive’s available storage space. This can help confirm that the transfer completed successfully.
Step 8: Safely Eject the USB Drive
When you are finished using the USB drive, do not immediately pull it out of the computer. First, use Windows’ Safely Remove feature.
In File Explorer, right-click the USB drive and select Eject. You can also select the USB-related eject option from the taskbar’s notification area if it is available.
Wait until Windows indicates that the device can be removed safely. Once it is safe, unplug the USB drive from the computer.
Safely ejecting the drive reduces the chance of data corruption, especially if Windows is still completing a write operation in the background.
Organize Your Files on the USB Drive
Once you know how to transfer files, you can make your USB drive much easier to use by organizing its contents into folders.
For example, you could create separate folders named Documents, Photos, Videos, and Work Files. To create a folder, right-click an empty area inside the USB drive, select New > Folder, and give the folder a descriptive name.
Good organization becomes especially useful when you use the USB drive for backups or regularly transfer files between multiple computers.
Faqs
Can I add files to a USB drive without deleting them from my computer?
Yes. Use Copy and Paste rather than Cut and Paste. Copying creates a duplicate on the USB drive while keeping the original file on your computer.
How do I copy multiple files to a USB drive?
Open the folder containing your files and select multiple items using the Ctrl key. You can then press Ctrl + C, open the USB drive, and press Ctrl + V.
Why is my USB drive not showing in File Explorer?
Try unplugging the USB drive and connecting it to another USB port. If it still does not appear, restart your computer and check again. A damaged drive, connection issue, or driver problem can also prevent Windows from recognizing it.
Can I drag files directly onto a USB drive?
Yes. You can open the folder containing your files and drag and drop them onto the USB drive. For beginners, however, Copy and Paste can be easier because it clearly separates selecting the files from transferring them.
Can I add a whole folder to a USB drive?
Yes. You can copy an entire folder to the USB drive just like an individual file. Windows will transfer the folder and its contents.
Why can’t I copy a large file to my USB drive?
The USB drive may use a file system such as FAT32, which has a maximum individual file size of about 4 GB. If you are trying to copy a larger file, the drive may need to use a different file system, such as exFAT or NTFS, depending on how you plan to use it.
Is it safe to remove a USB drive immediately after copying?
It is better to use Eject or Safely Remove before unplugging it. This gives Windows a chance to finish any remaining write operations and helps protect your data.
Summary
Adding files to a memory stick or USB drive is a simple process once you know where everything is located. Connect the drive, open File Explorer, find the files you want to transfer, and use Copy and Paste to place them on the USB drive.
For the safest approach, keep the original files on your computer by copying them rather than moving them. After the transfer finishes, verify that the files are present on the USB drive and use Eject before physically removing it.
Once you get comfortable with these steps, you can quickly transfer photos, documents, videos, music, PDFs, folders, and other files between computers using a USB drive.
