Finding created/modified time of files in a folder
Today we are going to learn about how to retrieve the created time and date of all files in a folder.
This is useful when you want to track the session information of certain files or folders.Lets look the code below.
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.io.File, java.util.Date, java.util.Calendar" errorPage="" %>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<%
String dir_name = "C:\\foldername";
//String dir_name = "/"; This line will give u the windows drive's root folder.
File fold = new File(dir_name);
if(fold.exists())
{
String all_files[] = fold.list();
int no_of_files = all_files.length;
for(int i=0; i<no_of_files; i++)
{
File f = new File(dir_name + "\\" + all_files[i] );
String complete_file_name = f.getPath();
String file_name = f.getName();
long last_modified_ms = f.lastModified();
Date date = new Date(last_modified_ms);
Calendar cal_date = Calendar.getInstance();
cal_date.setTime(date);
String last_modified_date = cal_date.get(Calendar.MONTH) + "-" + cal_date.get(Calendar.DATE) +"-"+ cal_date.get(Calendar.YEAR);
String last_modified_time = cal_date.get(Calendar.HOUR) + ":" + cal_date.get(Calendar.MINUTE) +":"+ cal_date.get(Calendar.SECOND);
%>
<a href="<%=complete_file_name%>"> <%=file_name%> </a> <b>Last Modified by </b> <%=last_modified_date%> <b>at </b> <%=last_modified_time%>
<br>
