Where does Internet Explorer keep downloaded files that are merely “opened” on Windows 7?

I decided to open a file instead of saving it, made lots of changes saved many times, but when I closed it, I realised I couldn't find it anymore.

I'm hopping the file is still here, but can't find it anywhere. Is there any way I can recover this file?

PS: it seems the file should be still there somewhere, because if I re-open the original file from the page it puts the "[2]" in the end of it, which could mean it conflicted with some original file.

Solution 1:

Windows 7 puts them in a directory in your profile directory

%userprofile%\AppData\Local\Microsoft\Windows\Temporary Internet Files

Solution 2:

On Windows 10 (and maybe others), the files that you opened in IE, instead of hitting Save first and opening that, are saved here:

\AppData\Local\Microsoft\Windows\INetCache\IE\PGLMIFME\
