If at all possible, could you please tell me step by step how to move all my files to an external drive, and how to retrieve them to reinstall them later? I’m really not comfortable doing things on the computer, always afraid I’m going to mess something up.
Moving files to an external drive or USB flash drive, is easy and necessary when buying a new computer or reformatting your hard drive. You can do this by using Windows Explorer and dragging and dropping your files to the external drive or using the “Send to” option.
Hooking up the External Drive
First, you must have an external drive or USB flash drive attached to your computer with sufficient storage capacity. These usually connect to a USB port. Follow all manufacturer installation instructions.
Launching Windows Explorer
Windows Explorer represents the contents of your computer and any attached storage devices by listing the different drives, folders, and files. There are several ways to launch Windows Explorer. The easiest way is to right-click the Start button and choose Explore.
Dragging and Dropping Files to an External Hard Drive
If you want to use the drag and drop technique, open a second instance of Windows Explorer and make sure that both of the windows show up on the screen. Try to place them side by side. In the left side window of Windows Explorer, click on your computer’s hard drive (usually the C: drive); in the right side window, click on the external hard drive (this will be a higher letter such as the E, F, G, H, or even F drive. The external drive may be identified with a label that says, “external storage device” or something similar.
Once you have the windows lined up, you can then go to the C: drive and drag and drop entire folders to the external drive. The dragging and dropping process involves clicking on the folder (such as My Documents) and keeping the mouse button depressed while you drag the folder across the screen to the external hard drive’s screen. Once you reach the drive, release the mouse button to release the folder. You’ll see a visually display on the screen showing files being moved from one folder to the next. Depending on the size and number of files, this could take a while to complete.
Note that you can use the Control button while clicking folders to select multiple copies.
Using the “Send to” Option
If you don’t like the idea of using two windows and dragging and dropping, you can use the “Send to” option to send your folders to an alternate location such as the external hard drive. Open Windows Explorer by right-clicking Start and choosing Explore. Click on the C: drive to see its list of folders. Find the folder that you want to send to the external hard drive and right-click it. Choose Send to and then find the hard drive in the display that appears.
Which Files to Copy
We’re primarily concerned with copying data files, not system or program files. While My Documents is fairly obvious, you likely have other locations where data files are stored. Make sure to consider all possible folders where you may be storing data. It’s helpful to make a checklist of all of your most important file types and then mark them off the list as you go. Your list might look something like this:
- My Documents
- Microsoft Money data
- Photos of kids
- Recipes
- E-mail messages
- E-mail contact lists
- Tax records
Reinstalling Data Files
Once your computer is restored or you’ve purchased a new computer, getting the files off of the external drive uses the same process, only in reverse. Simply open Windows Explorer, select the folders that you want to copy and drag and drop or choose “Send to.”
