Default hiding extensions by default

I have a small Hex Editor that will read anything. As long as I ONLY
READ it, nothing gets screwed up. Most of the time binary files are not
readable anyhow, but the header will contain some regular text, showing
me that the file is a .jpg image or a .exe file, etc...

I often use that to open something in my browser cache. Those cache
files have no extensions, and maybe I want to save an image that a
website wont allow downloading. Using the hex editor, I can see if a
file is an image type. If it is, I can rename it with the extension and
view it. The file sizes usually tell me if the cache item is htm (text)
or more likely an image or sound file, etc...

If you open mystery files in IrfanView, then - at least if it's one of
the common image formats, I'm not sure if it now does it for other types
- if it is a type it recognises, it will popup something like "xxx is a
..jpg file with incorrect extension. Rename?" (Even if you say no [in
which case it doesn't rename!], it still _displays_ them.)
