The File Explorer in Windows 10 is fairly customizable. You can change folder icons, drive icons, add or remove folders from Favorites, and show or hide the ribbon, and do much more.
Up until now, one of the issues with the File Explorer and Windows 10 was that there was no way to change the font size of File Explorer and other areas of the operating system. The only workaround was to change the scaling, but it has its own issues.
Fortunately, starting with Windows 10 Redstone 5, there is a built-in option in Windows 10 to change the text size of all areas, including the File Explorer.
The only downside of this new option is that it doesn’t allow you to change the font size of only the File Explorer. In short, when you increase or reduce the text size of File Explorer, the new text size is applied to other areas of the operating system as well.
If you find the default font size used in File Explorer and other areas of Windows 10 is little smaller than what you like, you can change it. Here is how to do that.
Change Windows 10 File Explorer text size
As mentioned before, you must be running version 1809 (Redstone 5) or later versions of Windows 10 in order to change the File Explorer font size.
Step 1: Open the Settings app and navigate to Ease of Access > Display.
Step 2: Under the Make text bigger section, move the slider towards to the right-side of the screen edge to increase the text size.
The “Sample text” box located just above the slider displays the live preview of the new text size. If you are happy with the new text size, click the Apply button.
The good thing is that you don’t need to log out to apply the change. The new font size will be applied in a few seconds after you click the Apply button.
