USB Flash Drives

  • If your computer does not come equipped with full size USB ports, or a port of a different kind, such as USB Type C, you may need to purchase a dongle to be able to connect full sized USB accessories to your machine.

External Hard Drive

  • External hard drives typically offer the largest amount of storage space for the money, and easily connect to your computer via USB.
  • There are both portable and larger form factor external drives on the market. The difference is not only in their size, but larger external hard drives usually require external power, while portable drives only require a USB connection. Keep this in mind if you would like your external drive to be portable.

SD or Micro SD Card

A 32GB microSD card


  • Your computer may have an available SD or Micro SD card slot. While this type of storage does not typically afford the same amount of space as the other options listed, its ultra compact form factor can still be very desirable for removable storage.

  • To use this type of storage, simply insert the SD card into the available slot.
  • The card itself can only be inserted into the slot in one way. These card slots are typically spring loaded, and the card should click into and out of place.

4. Get Started with Microsoft OneDrive

OneDrive is free cloud storage that comes with your Microsoft account. It’s like an extra hard drive that’s available from any of the devices you use, so the files you save there are always with you. If you have no accounts signed in to OneDrive or need to create an account, follow these steps.

  1. Select the Start button search for “OneDrive”, then click the OneDrive desktop app.
Start menu search highlighting the OneDrive app.

  1. Sign in with your Microsoft account and password, Typically Microsoft account holders already sign in when they sign into their user account after starting their System. Local account holders will need to sign in and, may need to create a Microsoft account if you skipped the account creation process when setting up Windows 10 for the first time. 
  2. When OneDrive Setup starts, enter your work or school account if you do not have one, select Sign in to set up your account.

5. How to Use Microsoft OneDrive

When getting started with OneDrive there are two screens in OneDrive Setup that are helpful to watch for:

  1. On the This is your OneDrive folder screen, take note of the location.
  2. If you want to change the folder location, select Change location - this is the best time to make this change.

  1. Select Next once you are satisfied with the location.
  2. On the Sync files from your OneDrive screen, choose the folders you want to sync. This helps control the amount of space OneDrive files take on your computer and conserves bandwidth during sync processes. You can change this later in Settings, but this is a good opportunity as well.
