Help please....am learning how to use my digital camera for home video of our new baby. Copied lastest onto CD ROM but when I try to view them using QUicktime am being told that format is not supported. How can I change the file type so that Quicktime can read it????
Thx.

I’m guessing you’re using a canon digital camera. thm files are thumbnails for the video files (and may contain additional info - I don’t know). They can be viewed by changing the extension to jpg. The video file should have extension avi.

Open an explorer window (any will do... My Documents, My Computer, whatever...) Go to tools, folder options. Go to the view tab. Uncheck hide extension for known file types, and check show hidden files and folders. Now go to the .thm file you want to change the extension to. Right click and choose rename, and where it says .thm replace it with .jpg

P.S: If you need to do this to a lot of files, get back to me. You can do it via the command prompt by using the ren command. (The exact command is “ren *.thm *.jpg” without quotes)

wow, i got to view my .thm file by changing the extension file to rar and it shows the files and extract with the rar.
