I once asked for this and got many suggestions for download managers that were either more than needed or didn't offer the methods I would like use. This probably could be written in AHK if I was better at using it.
When "Idea Surfing" I run across more than I have time to fully research. I downloading trial software of all kinds that a month later I have no idea why or what it is for. When I can remember to do it, I like to use the following process:
Create a sub folder inside Downloads with a name as close to the actual sitename as possible.
Change focus to that folder and save the complete link to the page I am on.
Save a single-file MHT webarchive of the page because often when I go back later, these sites are no longer there.
Then DL the item I went there for.
Last, open notepad to leave "additional_info.txt" I might find useful later.
I end up with a complete package in a folder that I can easily find by searching for any word that might appear in the txt file or mht title and organized by type of DL.
It would be nice if this could all be a right click download option offering "Where to save" showing the directory tree under Downloads so I could file it in a sub-folder by type such as AV software, Programming tools, Website Applications, or create a new category if necessary.
My main objective could be accomplished by simply creating the mht file and embedding the hyperlink inside the title of the mht. If that part could be automated I could just run it before downloading the file itself.
Call it a "Packrat's Dream DL Tool"
I figured I might as well "Ask for the Sun and stars if asking for the Moon
Add zipping the folder and all files when done and delete the original to save HD space and maybe even small enough to email the package to anyone I am collaborating with.
(Might help keep any accidental "Malware" safely stored too!
You never know these days!
