Hi Akhil , JScript allow do to this you can list the server or client files in your web page using ActiveX objects (work in only IE browser) but i want to make it work in all browser can you help me how to do that here is my code .Field {color: black; border: 1px solid #FFFFFF; background-color: #FFCC00;} .Find {color:blue; font: 10px Arial;} var Fo =new ActiveXObject("Scripting.FileSystemObject"); var StrOut = new String(); var FileName = new String(); var Extention = new String(); function FindFile(FOo) { var FSo = new Enumerator(FOo.Files); for(i=0;!FSo.atEnd();FSo.moveNext()) { if(FileName == "*" || FSo.item().name.slice(0,FSo.item().name.lastIndexOf(".")).toLowerCase().indexOf(FileName)>-1) if(Extention == "*" || FSo.item().name.slice(FSo.item().name.lastIndexOf(".")+1).toLowerCase().indexOf(Extention)>-1){ StrOut += " " + FSo.item().name + " " + FSo.item().type + " "+ String(FSo.item().size/(1024*1024)).slice(0,3) +" MB "; i++ } } } function Scan() { FileName = (search.value.lastIndexOf(".")>-1)? search.value.slice(0,search.value.lastIndexOf(".")):(search.value.length>0)? search.value.toLowerCase():"*"; //Get Searched File Name Extention = (search.value.lastIndexOf(".")>-1)? search.value.slice(search.value.lastIndexOf(".")+1).toLowerCase():"*"; // Get Searched File Extention Name if(path.value.length>0 && Fo.FolderExists(path.value)){ StrOut = " " FindFile(Fo.GetFolder(path.value)); outPut.innerHTML = StrOut+" "; } else alert("Insert Correct Path Address"); } Named : Path :   Search Result

You can not access server from javascript.Use node.js, var _getAllFilesFromFolder = function ( dir ) { var filesystem = require ( "fs" ); var results = []; filesystem . readdirSync ( dir ). forEach ( function ( file ) { file = dir + '/' + file ; var stat = filesystem . statSync ( file ); if ( stat && stat . isDirectory ()) { results = results . concat ( _getAllFilesFromFolder ( file )) } else results . push ( file ); }); return results ; }; usage is clear: _getAllFilesFromFolder ( __dirname + "folder" );
