How to Change File Properties

Windows

Open the File Explorer Windows Start Explorer. You can do this by clicking the folder icon on your taskbar, or by pressing Windows key + E on the keyboard.

Browse for the file you want to modify. You can use the Search bar in the upper-right corner to search by name, or select a drive and/or folder to browse using the left panel.

Right-click the file you want to change. A context menu will expand. If you want to modify the properties for more than one file at a time, select each file you want to edit while holding down the Control key. Then, right-click the highlighted area to bring up the menu.

Click Properties on the context menu. This opens a window containing the properties you can modify for this file.

Opens with: Near the top of the General tab, clicking Change next to this option will allow you to pick a different default program for the selected file.

Click the Details tab. This tab is going to look pretty different depending on the type of file you're editing. If you're looking at a photo, for example, you'll see the image's dimensions, resolution, and even some metadata from the camera that captured it.

Change a property on the Details tab. To change a property on the Details tab, click the mouse cursor on the value of the property (such as the Date Taken on a photo, or the Genre on an MP3 file), erase what's there, and then start typing. Click Remove Properties and Personal Information at the bottom to see which properties you can completely delete.

This makes it easy to search for the file on your Mac by tag name. More Info: This tells you some information about the file, which will vary depending on the type of file you're looking at. For example, if you're looking at a photo, you'll see the photo's dimensions, some information about the camera that took it, and details about the colors included. Name & Extension: Change your file's name or file type here. You can also check the "Hide extension" box to hide this particular file's extension. Comments: Add notes about the file. Open with: Change the program with which your file opens. Preview: View a preview (e.g., thumbnail) of the file. Sharing & Permissions: Here's where you can change who can read, edit, or modify the file. If you're editing a music file, you may see options for changing the name of the song, artist, genre, or other specifics.

Save your changes. When you're done making changes, you need only click the red circle in the top-left corner of Get Info window to save them.
