.mht files, it appears, are single file web archives created by Windows Internet Explorer.
Is there any way to import these into DT so that they are searchable?
The only program I’ve found so far that understands these .htm files is MS Word.
Note that these files appear to be very different from HTML files.
OOPS! It appears that right clicking and choosing Convert does the trick. Very pleasantly surprised…will need to test some more to see if the results look ok.
You should be able to import them like any other files, e.g. via drag & drop or via File > Import > Files & Folders. Are you able to view them e.g. with Safari?
but I just updated my question. It appears that DT is able natively to convert these odd files to various other formats them by simply right clicking and choosing Convert.
