How to check if the file is empty

An empty file would have no content in it at all. Remember, all of these JSON, XML or CSVs have one thing in common. They are all containing string data. You can check against that string data, to determine whether they are emtpy or not. 

 

For example,

 

if(File.ReadAllText("") == "") {
    // Empty
}  else {
    // Nope, there is something
}

 

This way you can check whether a file is empty or not. Also, you need to have the full name of the file otherwise you won't be able to check it. First step is to have the file-location (full location).
