I've got a suggestion for a procedure that has server me well for over 20 years.
I'm a download junkie!
Lost everything on download.
Go to C:\............ New folder
open new folder named All Downloads
When I find a download I save it to All Downloads.... Always!
Mostly I save web pages.. go to Save Page.... Save As.......save as an html file.
Saving as html you get the "webpage.htm" and it opens a folder to contain "the includes" with the same name as the htm file...
The includes are all the files necessary to render the page with all the images, etc.
SO..... you now have all the images, CSS pages etc.
The images may be in any of several formats. Wrong format?
I use IrFanView to convert, view, rotate , or anything else you can do with an image.....
It also does screen captures.....
Freeware... I wouldn't be without it.
Save everything to All Downloads and web pages in html so you can edit the page if you want and you have a folder containing all the images, etc.
Why All Downloads?
The folder stays near the top of list because of the A in All
All Downloads for every download....... every time!
exe files, pdfs you can move to where you want them OR copy them to where you want them and leave the original in All Downloads so you can go back and get them again when you goof... and again when you goof???
I've used this idea in every O/S from Win3.1 to Win8.1.1. I'm not very smart but I know where to find everything I download.
