When you have a bunch of photos in a folder Windows chooses the default picture it displays when you have the view set to thumbnail view at Medium or larger. Typically, Windows will choose one of the first four listed in the folder. Or, it will just display a Windows default picture icon. But you might want to customize things a bit. Especially, if you take a lot of photos, it can make finding the right collection easier with a visual cue. Here is a look at how you can make any picture you want a folder’s default one that displays when you open File Explorer.
Change Default Folder Picture Windows 10 File Explorer
First, open File Explorer and right-click on the folder you want to change the default picture and choose Properties from the context menu. Then click the Customize tab and click the “Choose File” button. For example, here I am changing the default photo for the folder named “Saved pictures”.
Then browse to the location of the image you want to use. It can come from the same folder or any other accessible location including another drive or Cloud storage like OneDrive or Dropbox. Click OK and you should see the folder picture has changed. If you don’t see it right away, just refresh the folder.
Another way you can do it is by using a trick that has been around at least since the XP days and earlier. This trick allows you to set a specific picture in a folder to display as the default. Where the method above lets you choose from any location. Now, since you are renaming the picture, you should make a copy of it in that same folder first, and then rename it.
Open the folder with the picture you want to set as default. Then rename the picture you want as “folder.gif” and click “Yes” to the confirmation dialog that comes up. Now when you go back, the image you renamed will be displayed.
Keep in mind that if you use the first method described above where you change the folder’s properties, the image you choose there will override anything you have set at by renaming it to “folder.gif” so use one or the other accordingly.
