Your numbers are a little unclear.
In order to tell you what you want to know, I need two numbers from you - 1) How much empty space you have, and 2) How big are the files you want to put into the empty space. When I have those numbers I can tell you how many of those files you can fit into that space.
Follow the steps I listed in my first post. In step 1 you will get a box that looks something like this:
The number next to the words
Free Space tell you how much free, empty, available space is on your hard drive, measured in bytes.
In step 2 you should get something that looks a little like this:
The numbers under the
Size column tell you how big each file is, measured in KB (kilobytes). 1KB = 1,024 bytes.
In my examples above, I have 13,757,632,512 bytes free on my C: drive, and most of my pics are between 1,500KB and 2,000KB.
So let's assume that my pics are about 2,000KB each. 2,000 X 1,024 = 2,048,000 bytes, so most of my pics are 2,048,000 bytes.
I have 13,757,632,512 bytes of empty space on my hard drive. 13,757,632,512(space available) / 2,048,000(size of pics) = 6717.594(number of pics), so I can fit 6717 pics on my hard drive.
