Find files or directory in client or server site with JavaScript


Maybe you want to have list of  server or client files in your web page to uploading or downloading or changing . JScript allow you to do this. You can capture all files type , size , properties in all directories and use them easily. In this sample I use this technique for searching files in local hard drive.

Necessary Attention: your browser should have access to run ActiveX objects. If receive a error message telling "Automatic Server Can't Create Object" you most go to Internet Option and in security tab select custom level in Local part and change options to get effect.

ActiveX Objects

For working with Files and directory you should make a server object as Scripting.FileSystemObject then with GetDirectory() method can get a directory object. If you want know the directory is use FolderExists().

var Fo = new ActiveXObject("Scripting.FileSystemObject");


Enumerators are an array of Directory or File objects such that you can use methods to get special file or sub directory that are in defined path. Enumerator have some methods I have called like atEnd() and moveNext() in my sample.

function FindFile(FOo)
    //Get array of files including in FOo directory object
    var FSo = new Enumerator(FOo.Files);
    // Getting all files in FSo object
    for (i=0;!FSo.atEnd();FSo.moveNext())


Files Object Properties

For getting a object that is in Enumerator object you must use item() and it returns a file or directory object that are in current place of Enumerator. Then you can use Files properties that are listed.

  • Attributes
  • DateCreated
  • DateLastAccessed
  • DateLastModified
  • Drive
  • Name
  • ParentFolder
  • Path
  • ShortName
  • ShortPath
  • Size
  • Type
FSo.item().name // File name
FSo.item().type // Description defining the file extension
FSo.item().size // File size in byte

GeneralThere are 2 bugs left in my source code. PinmemberUno198214-Jul-09 6:43 
The first one which isn't that big of a deal is the toggle varible that seperates the files and the background color so that each file stands out. This is due to the code not remembering the last toggle color upon entering a new loop (directory). The second bug is that the application does not remember the original directory value and place this value back into the search text box upon completing the search. Other than that this is a solid web based search application.
All source files inluding completed app is included in the link below.
