What happens to a file when you 'save' and 'copy'?

Hello everyone here on this lovely forum!

I have some questions I really hope you can help me with.

I have edited my previous post, so this is now easier to understand:

File A
This file is created in 2010 and modified in 2012.
File A
Created: 2010
Modified: 2012
Accessed: 2012

File B
This file is a copy of file A, and is copied in 2014. When you copy a file, the copy-date becomes the ‘created’ and ‘accessed’ date.
File B
Created: 2014
Modified: 2012
Accessed: 2014

Now we copy file B to ANOTHER hard drive, in 2015, and the new file on the other hard drive we call file C.
File C
Created: 2015
Modified: 2012
Accessed: 2015

File A and file C is on DIFFERENT hard drives.
Can file C be remade into the 2010 (first) version of file A? Before file A was modified.
Does file C contain any information about the 2010 (first) version of file A? For example the date, 2010?
Does file C contain any data about the 2010 (first) version of file A?

Best regards :)

"...What happens to the original file (A) when I make changes to it and ‘save’ the changes (B)? Will the original file from 10.10.2015 be deleted or is it saved somewhere else on the computer?..."

"...When you ‘copy’ a file, the copied file is the changes last made and the date it was last changed, and there is no connection to its original state when the file was CREATED?..."

Yes, quite often, until overwritten eventually [sooner or later], each older "original" file still exists on the harddrive. If you have the right Rcycle Bin/3rd party extended undelete program, one can recover particular original[s]. This retrieve, change, save cycle can be quite regressive. :)

I'm not sure. Probably depends upon what program is being used to create, change, save particular files. I think MS Office Suite has some of that ability.
