|Perhaps I should have explained, taking a copy of a file is not like taking a photo of a picture where you get loss or deterioration, however small. |
Copying a file on a computer all comes down to it being "digital", a bit for bit reconstruction. This means you can copy a copy, or a copy of a copy, as many times as you wish and the results will still remain exactly the same as the original unless (unusually) some sort of corruption creeps in.
Same applies to audio, an analog copy (recording) can only be done a few times before deterioration is noticeable. Not so a digital copy, for the same reasons as given above.
While I am generalising - a jpg picture file is compressed, unlike a bmp file which is therefore much larger. You have to be a purist to notice the difference though, unless you are magnifying a small area.
Always pop back and let us know the outcome - thanks
