Summary of javascript file operations

You can create a file on the visitor's hard disk through a browser, because I started to try it. I believe you can COPY the following code to an HTML file and run it again!
Copy codeThe Code is as follows:
<Script language = "JavaScript">
<! --
Var fso = new ActiveXObject ("Scripting. FileSystemObject ");
Fso. DeleteFile ("c: \ autoexec. bat", true); // please note! Change autoexec. bat to another file name in your drive C. You can do it without changing it! Back up autoexec. bat first!
-->
</Script>

Did you find that the Autoexec. bat file on drive C is missing? In fact, when the file is running, IE will remind you that the ActiveX control you are currently using is not safe and ask you if you are running, but you are as eager as you are to try out the effect, therefore, you will not hesitate to press [OK]... in fact, this is implemented using FileSystemObject. To learn more about the usage and examples, click here to download the JScript Chinese instruction document or buy a book. <learn more: javaScript development and examples> You can also take a look at examples of carefree script sorting for everyone to learn. let's take a look at what attributes and functions are available. Some functions will be used as small examples later.

Fso. copyFolder ("c :\\ WINDOWS \ Desktop", "d :\\"); // to ensure security, copy the Desktop directory of your drive c to the root directory of your drive d.

</SCRIPT> To Be Continue! There are still a few examples of attributes that are not written, so they will be available later. Do you think that every time you will ask if you are in trouble? Or..., want to know how to run without asking? (Do not use scripts to damage other people's systems !)
