File size

File size is how much space a file takes up on a computer. It's like how many toys you have in your toy box. If you have a lot of big toys, then your toy box will be full and won't be able to fit any more toys. The same thing happens with computer files. If a file is really big, it takes up a lot of space on your computer and you might not be able to fit any more files on it.

There are different ways to measure file size, but the most common way is in bytes. Bytes are like little pieces of information. The more bytes a file has, the bigger it is. It's like how a big toy takes up more room in your toy box.

You can find out how big a file is by looking at its properties. It will tell you how many bytes the file has. If a file has a lot of bytes, it might take a long time to download or upload because it's a big file.

So, file size is like how much room a toy takes up in your toy box. The more bytes a file has, the bigger it is and it might take longer to download or upload.
