What is a .FSTHUMB file?
An .FSTHUMB file is a small image file known as a thumbnail, which is created by a video-editing software called Wondershare Filmora. This type of file is specifically used within the Filmora software to represent a preview image of video-editing projects. When you see the list of projects in Filmora's menus, each project is represented by an .FSTHUMB file, which makes it easier to identify and select projects quickly.
The .FSTHUMB file is not designed to be opened or viewed on its own because it serves a specific purpose within the Filmora program. It is automatically generated and managed by the software.
If you need to view or access these thumbnail images, you should do so through the Wondershare Filmora software itself. This is the main program that can recognize and display the contents of .FSTHUMB files. There is no benefit or typical functionality available by trying to open these files with other software.
