What we are going to do now is just look at computer file sizes and what that actually means, now computer data is measured in bytes, so 1000 bytes is a kilobyte. A 1000 kilobytes is a megabyte, and then a 1000 megabytes is a gigabyte, and a 1000 gigabytes is a terabyte. So when you are looking at file size, you might see it saying that the file is 100 kilobytes, another file might be one megabyte, then you might think that one is 100 and one is one, but actually the one is much, much bigger than the 100. When you are looking at files that are on the gigabyte side, these are big files, and if you have got files that you have downloaded onto your computer and they are in the gigabyte range, this will start eating up the storage on your computer, but also if you are trying to transfer files through the internet or a data transfer and things like that, as there is a maximum size, it will slow you down if the bigger the file size you are transferring, the slower it will be.

One area where a file size could be really useful knowing is if you want to email a document to somebody. So if you are emailing over a file to somebody, you want to make sure that there is no massive attachment, you can't send hundreds and hundreds of megabytes of data over in an email, you can only send small amounts. So have a look at the file sizes before you start sending emails to people, normally with most email programs, they will tell you if the file is too big to send, if you do have to send a file that is bigger, you would have to use some other type of file data transfer service, something like MailBigFile or WeTransfer.
