.thm file extension
- Video thumbnail file. File contains a thumbnail (i.e. a small static)
image taken from a video movie, used to depict the movie when browsing. The
base name of the file (i.e. without the .thm extension) will be same as that
of the corresponding video/movie file. For example if the .thm file is
123.thm then the video file might be 123.avi.
The .thm file also contains Exif information (such as when the video was made, the type of camera etc) and some applications may make use of this. The .thm file, may therefore contain some information that is not available in the corresponding video file.
A .thm file can be opened and viewed using Windows Picture and Fax viewer. Other graphics programs may also be able to open a .thm file. Alternately renaming the file to have a .jpg extension will allow it to be opened and viewed using most imaging software.
