Sublime Text IDE Issue!

Question

Whenever i create a new file with a specified format and save it, it is saved without any format and then i have to rewrite the format with it and then it converted to that format. why does it happen??

Answer 1

in sublime text a file should have it's language at the end of their names
for example:
file.py is in python
file.cpp is in c++
if you just write "file" it is saved as a simple text file:)

Answer 2

I mentioned it already that i write the format like .html .css etc and still it does not pick it up. and when i do it manually by remaining the file and putting the format at the end then it works.
