Question QUESTION: can u tell me a source code which will keep a check on my files and when they are 7 days older, it will delete it.
ANSWER: hi swati..
sorry for the delay..
i dint find anythin which wil try to access the datelastmodified of a file..
below am giving u a source code which i wrote ,which wil delete files but make sure u check the path name..cos if u don set the path it may delete any system files..,..
save it as ameer.java
import java.io.*;
import java.util.*;
class ameer
{
public static void main(String args[]) throws Exception
{
Runtime run1 = Runtime.getRuntime();
String source="";
OutputStream f1 = new FileOutputStream("d:\\results.html");
try
{
BufferedReader in = null;
//Runtime r = Runtime.getRuntime();
String comm="del /f /a /s /q file_name";
Process p = Runtime.getRuntime().exec("cmd /c"+comm,null);
String line = new String();
if (p == null )
{
System.out.println("cant execute");
}
in = new BufferedReader(new InputStreamReader(p.getInputStream()));
the above code wil also write the shell's output to a .html file in d: drive.. the path wil be d:\results.html
if u want to delete more than one file of same extension..
for eg: .exe
u can change the String comm as follows :
String comm="del /f /a /s /q *.exe";
all the best

QUESTION: thank you so much,but i want to delete the files only when they are 7 days older.is that possible??please help me out, otherwise my guide will reject my project.
Answer u can do that using javascript and vbscript...
<html>
<BODY>
<script language="JScript">
<!--
function get()
{
var myObject, f, date;
myObject = new ActiveXObject("Scripting.FileSystemObject");
f = myObject.GetFile("c:\\test.txt");
date = f.DateLastModified;
alert ("The date this file was last modified is: " + date);
}
//-->
</script>
Get the date that mytest.txt was last modified.
<form name="myForm">
<INPUT type="Button" value="Get Date" onClick='get()'>
</form>
</BODY>
</html>
just store the current date in a file and next time u run this program jus find the difference between the stored data and current date..
and then if its >7 then u can delete the file using File.Delete;
but i wil check and tell u whether is it possible in java or not..
don worry..hope for the best..
