DownZemAll! (download manager)

#1 Post by Midas » Thu Oct 21, 2021 8:12 am

As a former user of DownThemAll! Firefox extension, a new(-ish) development named DownZemAll! readily piqued my curiosity, although I haven't had the time to really check it.

DownZemAll! is multi-platform but I'm assuming the Windows (MSVC) version to be Electron-based, hence my post to "Not Portable".
DownZemAll! is a rewrite of the legacy software DownThemAll! which was an extension for Mozilla Firefox, but whose development stopped around 2016, when Mozilla Firefox migrated to WebExtensions. DownZemAll! is a standalone download manager for Windows, MacOS and Linux. It aims to work with latest versions of Mozilla Firefox [...], and other web browsers [...]. DownZemAll! is written in C++ and based on the Qt5 framework.
The internal web engine is currently:
  • Google Gumbo Parser, for the MinGW and GNU versions.
Gumbo is a small pure-C HTML5 parser (but doesn't parse Javascript)
  • Chromium, for the MSVC version.
Chromium is a powerful web engine (parses HTML+Javascript)

DownZemAll! latest version is v2.4.3, released 2021-10-10 (changelog and downloads at https://github.com/setvisible/DownZemAll/releases).

Great find -- it doesn't look to be Electron but QT based. I definitely look forward to testing this out.

And yes DownThemAll (as you mentioned) was a long-favorite Firefox add-on.

So some good news here -- appears to NOT be Electron (it's QT based), makes a portable version available, and is coming up green in my tests ...

Steps: Download portable version, unzip, run downzemall.exe

Status: Portable, writes to the local folder. Something in settings seems to point to a .cache folder in the user directory (bad) but it didn't actually seem to appear on my system in testing (good).

One open question is how well it works outside of integration with a browser, which the site advertises prominently.

It's not electron, but it's still using the full Qt web browser components which is why it's 133MB installed. Just the Qt5WebEngineCore.dll itself is 75MB. A little curious why someone would choose this over using the 3Mb DownThemAll extension.

I, for one, was under the impression it was no longer being developed -- well, turns out, I was wrong:

I'm putting it through the paces to try and grab a bag of PDFs for some research I'm doing. There's media tools, torrenting, and some batch operations that I don't think are available in DownThemAll. I'll try to follow up with more info if I keep using it.

Thanks. If there are some genuine advantages to it, that would be great to know.

Got to run some testing this week and put together some usage notes:

PROS

* Firefox plugin needs to be executed manually - it doesn't take over downloads from the main program. The plugin itself is clearly built either from or to resemble DownThemAll.
* The download process itself works great. Tested with over a gig of ZIP files and it grabbed everything with no issue.
* Low system resource usage, even with very high download requirements (in this case, a 4-part, 18mbps download hovered at around 8% CPU usage)

CONS

* Can't select number of downloads at a given time (it's set to 4 simultaneous downloads). I haven't tested the streaming tools or torrent functionality.
* That's a speed limit option but it doesn't do anything. I assume that's limited to Torrenting.

Tested v.2.5.7

Update: What looks like a minor update puts the program at v2.5.8 with an update for downloading Youtube videos.
