A Quick Introduction to the Drives in Microsoft Windows

May 7, 2025

Windows is, for the most part, the default operating system you can expect to see in a business setting. That said, some owners have never used a Windows computer before, instead using a simple Chromebook or a Mac. Still, it’s good to know how Windows works, especially since it seems there’s a significant gap in knowledge.

Today, we’re exploring how the different drives on Windows PCs work so you can make better use of your workplace tools.

For more information regarding the Windows OS, make sure you check out the rest of our “Learning Windows” blog articles.

Locate and Manage Your Drives

Windows 11’s drives can be found through the File Explorer. Open it up with the Windows Key + E shortcut. From here, you’ll see all connected drives in My PC. Here are the most likely drives you’ll see:

The C: Drive - This is the primary drive that hosts the operating system and most software you’ll use.
Additional Drivers and Partitions - Other drives and partitions (segmented portions of your existing drives) will be lettered alphabetically. They’ll be listed starting with C: since A: and B: are reserved for removable media that aren’t used often these days. Most business networks will have a network drive that is centrally located on the network rather than installed into the computer itself.
The Optical Drive - This is the drive that lets your PC read discs and other similar media. It will usually be the last drive listed.
External Drives - These drives are listed in the File Explorer when you connect them to the computer.

To explain it in different terms, you can think of the File Explorer as the Windows version of Finder. You can also create new folders and move files without too much trouble.

Good News: You Can Add More Storage

The thing about Macbooks is that you usually can’t add additional drives. While you might be able to swap one out for larger storage, or connect an external hard device, you simply can’t add more internal drives to certain Mac models.

Windows makes it easy to add as many drives as your motherboard is compatible with, or as many as the case can hold. If you have more ports, you can connect more drives. The form factor does play into this, though, and you want to make sure the hard drives match your PC hardware.

The Business Reality of Hardware Lifecycles

Most business owners treat their office computers like breakroom microwaves: they expect them to work until they physically stop turning on. It’s a logical approach for a toaster, but in the professional world, a computer becomes "old" long before it actually breaks.

How to Manage BYOD (Without the Headache)

With smartphones as accessible as they are, it’s no small wonder how company-only policies have all but faded into obscurity in the workplace. Whether you allow it or not, you can bet that your team is using their smartphones to get work done, whether it’s checking email from their couch or sending you a quick DM. In other words, you need a Bring Your Own Device (BYOD) policy, as it is practically the new accepted standard.
