WinZip, 7-Zip and DOpus

I downloaded and installed AB's excellent Beyond Compare script — thank you very much AB for sharing the Vegemite. In the process:

  • I found that I could not extract AB's zipped .osb file using the DOpus command "Copy EXTRACT=sub Here", but I could extract it using 7-zip (I could of course have changed the extension to .zip).
  • While I was fiddling around, WinZip came up and declared itself to be out of date (Ver15.0.10039), and demanded 26 pounds to update to Ver18.5 Standard!

I immediately downloaded the standalone 7-zip programme and started replacing my various zip buttons with 7-zip commands and parameters (using DOS buttons). I then realised, however, that DOpus was talking about its "inbuilt" zipfile handling. Now I am confused.

  1. What is the inbuilt DOpus zipfile handler? Is it WinZip?
  2. Can I change the DOpus inbuilt handler to 7-zip, and would this be a better approach than the buttons that I have half-written using the standalone 7-zip?
  3. Is 7-Zip better or worse than the DOpus inbuilt handler, whatever it is?
  4. Why doesn't the inbuilt DOpus handler open zip files whose extension has been changed, as 7-zip does (DOpus does, after all, use zip files with a number of different extensions)? Similarly, why is it that when I right-click the .osb file and try to "open with" WinZip, nothing happens (this approach works with 7-zip)?
  5. Should I be uninstalling WinZip 15.0 if I don't update it to 18.5 as it demands?

You can also add .osp to the list of zip extensions Opus handles, under Preferences / Zip & Other Archives / Zip Files.

WinZip has nothing to do with Opus.

WinZip and Opus are unrelated.

Opus has its own zip code.

I don't know why you would want to do that.

Using Opus's own zip handler is better when working inside of Opus.

Apart from that, the two are quite similar.

Because it would affect double-clicking files, and there are about a million file types which are really zip files disguised with other extensions, where you do not want to enter them as archives when you double-click.

For example, .docx files made by Microsoft Word. It would be rather annoying if double-clicking a Word document showed you some cryptic archive contents instead of opening it in Word.

You can add extensions to the list Opus will handle as zip files if you wish to override it for specific cases.

Ask the people who make WinZip. WinZip has nothing to do with us.

You can do whatever you want with WinZip. We don't care. :slight_smile:

Thanks very much, Leo. You have a genius for making things clear to laymen.

As an aside, I have WinZip 15.5 installed on this computer, and mine doesn't "demand" anything, and neither should yours. I think there's a setting somewhere related to automatic updates checking for WinZip, which you might want to disable. In any case, you can use WinZip 15.0 as long as you like, or uninstall it today. The choice is yours.

Thanks for that, Pirx. I've already uninstalled WinZip, which will have killed any such setting. Dead men don't demand money.
