.THM File Extension

A THM file is a theme file used by Sony Ericsson mobile phones. It stores settings used to customize the user interface of the cell phone and includes custom window and text colors, icons, wallpaper, and other images. THM files can be created and edited using the free Themes Creator from Sony Ericsson.

A THM file is a thumbnail image generated by digital camcorders and software programs when a video clip is saved. It contains a small image from video clip's first frame and is used for visually browsing through a collection of video clips.

Video thumbnails are often saved to memory cards when video is captured on digital camcorders or digital cameras that record video. THM files may or may not be transferred to the computer depending on what software is used to import the video. Each THM file shares the same filename as its associated video clip. For example, "clip001.thm" would be created for "clip001.avi."

NOTE: THM files often are saved using JPEG formatting. Therefore, you can either try to open them directly in an image viewer, or you can change the file extension to ".jpg" and open them with any .JPG viewer.
