asked on

figuring out extensions

make a text file
compress it
rename it to .jpg
compress it again
 rename it to .jpg

it is not a .jpg, but will allowed to say so.

why did windows allow this? is it just a way to anonymize a file, if need be?

when you rename a extension, does it corrupt the file by any chance?

if the extension is renamed, is there any tool to extract the original extension in which it was created?
