Just imagine what hackers could do if JavaScript had access to your filesystem... — gcampbell, Jul 04 '16 at 18:30

It seems from a comment that you're using ActiveX. Good luck persuading Mozilla and Google to support it. — gcampbell, Jul 04 '16 at 18:36

what you could do, is to create a virtual file with JavaScript, which would be downloadable like any other file on a remote server — webdeb, Jul 04 '16 at 18:48

It's not possible. It would be a major security risk if browsers could write anything on the user's filesystem.

Best you could do is create a text file on your server, and serve it for download.

if I use that code, it's working, but the file goes directly on the desktop... If I change the filename to C:\test\testfile.txt, nothing happend... var ForReading = 1, ForWriting = 2, ForAppending = 8; var TristateUseDefault = -2, TristateTrue = -1, TristateFalse = 0; var fso = new ActiveXObject("Scripting.FileSystemObject"); var filename = "testfile.txt"; fso.CreateTextFile(filename); var fileObj = fso.GetFile(filename); var ts = fileObj.OpenAsTextStream(ForWriting, TristateUseDefault); ts.WriteLine("Hello World!"); ts.WriteLine("The quick brown fox"); ts.Close(); – Thomas Jomphe Jul 04 '16 at 18:33
@ThomasJomphe It shouldn't even be possible to write to the client's desktop. That must either be a vulnerability, or the browser realizing it's being served locally. You **cannot** write directly to a client's drive. The best you can do is make use of `LocalStorage`. – Carcigenicate Jul 04 '16 at 18:43
