hi friends,can any one give the coding for finding file size
using java script???

This method will find the filesize of files in the same domain as the calling page.
If no string is passed as an argument, the current page location is used.

call it like this: fetchSize(url)

function fetchSize(str){
    if(!str)str=location.href;
    var O= AJ(); //use your AJAX code, or AJ
    if(!O) return false;
    try{
    O.open("HEAD", str, false); // NOT asynchronous
    O.send(null);
    if(O.status==200){
    return O.getResponseHeader('Content-Length')+ ' bytes';    
    }
    else return false;
    }
    catch(er){
    return false;
    }
}
 
function AJ(){
    var obj;   
    if (window.XMLHttpRequest) obj= new XMLHttpRequest();
    else if (window.ActiveXObject) {
    try{
    obj= new ActiveXObject('MSXML2.XMLHTTP.3.0');
    }
    catch(er){
    try{
    obj=new ActiveXObject("Microsoft.XMLHTTP");
    }
    catch(er){
    obj=false;
    }
    }
     }
      return obj;  
}
