You can change the file extension on the file from “.mht” to read “.uue”. You can then open the “.uue” file up in a zip program such as WinZip.
You can then extract one or all the files contained in the renamed .mht file using the WinZip program interface.
Of course, you will have to change the file extensions on the extractedfiles because the extracted .html file will have a .txt file extension when extracted. For instance, when you are viewing the .uue file in WinZip the.html file will have the name 0001.txt and will also have that name and extension when it’s extracted. So once it’s extracted just change the name of the file from 0001.txt to myfile.html for example. Likewise, image files contained in the .uue file will contain extensions such as .001, 002, etc… and will have to be renamed with thier proper extension once they’ve been extracted.
