How is a file stored in Hard drives?

Question

Be it any file(image file, text file), how does it get stored in main memory? I mean in which format in computer memory and how does the process right from the creating a file to saving it into ROM happen?

Answer 1

So basically they are stored on hard drives as byte streams. And whatever we write in a file is stored as raw bytes as long as its not stored in memory? Btw what actually happens the time when its been created and not been saved?

Answer 2

Decoding, am i right?

Answer 3

Actually i am as i always interpreted decoding as converting a code into meaningful format

Answer 4

For ex: if we open a text file on notepad, doesn't it decode text file(encoded form) into meaningful data, isn't it true?

Answer 5

Oh! Btw wasn't my above example right?

Answer 6

My bad. I would say i start doubting myself when it comes to understand technical concepts. That's why implying may sometimes doesn't make me feel that I am right.
