Hi naunaYou actually dont have access to filesystem for example reading and writing local files however due to HTML5 File Api specification there are some file properties that you do have access to and the file size is one of them For security reasons ajax  javascript isnt allowed to access the file stream or file properties before or during uploadCodelthtml xmlns34httpwwww3org1999xhtml34gtlthead runat34server34gt    lttitlegtlttitlegt    ltscript type34textjavascript34 src34httpajaxgoogleapiscomajaxlibsjquery183jqueryminjs34gtltscriptgt    ltscript type34textjavascript34gt        function              34btnUpload34bind34click34 function                  if typeof 34fuVideo340files  34undefined34                     var size  parseFloat34fuVideo340files0size  1024toFixed2                    var sizeLimit  1024
