Overview
Ant Download Manager sits between your browser and the internet and takes over anything that would otherwise crawl through the browser's own downloader. It opens several connections to the same file, pulls the pieces in parallel and stitches them back together at the end, which on a connection that throttles single streams is the difference between a forty minute wait and a five minute one. The second half of the program is the video grabber, which watches the page you are on and offers a list of every stream it can see, including the segmented ones that browsers refuse to save.
This is the Pro build with the license module already handled, so there is no trial counter, no nag on close and no cap on how many simultaneous transfers you can queue. The browser integration extensions for Chromium and Firefox based browsers are bundled inside the archive rather than pulled from a store, which matters because the store versions check a license the offline build does not have.
How the accelerator actually works
The core idea is old and it still works. Instead of asking a server for a file and waiting, the manager asks for eight or sixteen byte ranges of the same file at once, over separate connections, and writes them into a sparse file on disk. Servers that limit each connection to a fixed rate end up handing you that rate several times over. Servers that do not limit anything see no difference, so the speed gain on a well behaved host is small, which is worth knowing before you assume the program is broken.
Resume handling is the part that gets used more than the speed. If a transfer dies halfway, the partial file and its range map stay on disk, and picking it up later continues from where it stopped rather than starting over. The manager also retries automatically on a schedule you set, so an overnight queue on a flaky line usually finishes without anyone watching it.
The video and stream grabber
With the browser extension installed, a small panel appears whenever the page has media on it. It lists every quality variant it can resolve, including separate audio tracks where the source keeps them apart, and it will mux the chosen video and audio into a single file on completion. Segmented streams delivered as hundreds of small chunks are downloaded in parallel and joined, which is the whole reason people install this class of program in the first place.
There is also a clipboard watcher for the case where the extension cannot see the media. Copy a link and the manager offers to take it, with a filter list so that copying ordinary text does not throw a dialog in your face every few seconds. The filter accepts wildcards and can be set to only trigger on specific extensions or hosts.
Queues, scheduling and where files land
Transfers can be sorted into categories that each have their own destination folder, so archives, video and documents separate themselves without you filing anything. A queue can be scheduled to start at a set hour and stop at another, which is useful on a metered connection with a cheap window overnight. Bandwidth can be capped globally or per queue, so a large download does not make a video call unusable.
The manager can also be pointed at a proxy per category, and it keeps a history of completed transfers with the source address, so re downloading something you deleted six months ago is one click rather than a search. History can be cleared on exit if you would rather it kept nothing.

- History database compacted on exit instead of on launch
Questions about this release
Does it speed up every download?
No. It helps most where the server limits each connection separately. Against a host that is already saturating your line there is nothing left to gain and the speed will look the same.
Why does the browser extension not appear?
The bundled extensions are loaded from a folder rather than a store listing, so developer mode has to be on in the browser. The install notes walk through it for both families.
Can it grab from any site?
It grabs what the page actually plays. If a stream is delivered in an unusual container the detection panel may show nothing, and no download manager gets around that.
Does it phone home?
The updater and the license check are both removed in this build, so it makes no outbound calls of its own beyond the transfers you start.
Comments
Extension loading needed developer mode like the notes say. Once it was in, the video panel works everywhere I tried.
Queue scheduler is the underrated part. I set it for overnight and wake up to everything done.
Comments are read before they appear. If a build stops working, say so here and it gets rebuilt rather than quietly left up.
Pulling from a host that caps at 300k per connection, this gets me the full line with 16 segments. Exactly what I wanted it for.
