The Shrink tetin file option removes header lines, comment lines, and unnecessary definitions in the Tetin files, which can reduce the size of the Tetin file significantly. The comment lines include the date and software version of the last modification.

Selecting this option will automatically open a browser window. Select the desired Tetin file. The number of lines removed will appear in the message window. From the browser window, you can either save the file with a new name or overwrite the original file.
