FilePro Helps You Analyze A Drive’s Space Distribution

Most computer users every now and then come into a situation where their hard drives start to run out of space. Sometimes it is easy to find out why. If you installed a big game for instance the other day you can be sure that it is now occupying lots of space on the computer’s hard drive. Sometimes though it may not be that obvious, and that’s where programs like FilePro come into play. It may for instance be the case that each save game requires Megabytes on the disk, and that the game’s auto save option has stored hundreds of save games on the computer.

These programs analyze the storage space distribution on hard drive partitions or folders to display the files and folders that occupy the most space on the PC.

The c: drive is selected by default when you start FilePro for the first time. You can change that to another hard drive partition or folder on the computer before you hit the Scan button to start the space distribution analysis.

The information are added to the program window in realtime as all folders and files of the computer are processed. The initial display is a tree structure map that displays folders based on their size in the program window. This way you can easily identify system folders like the Windows directory to concentrate on other folders of the system.

A left-click selects a folder, a double-click zooms in on that folder to display all the files and folders that are stored inside of it. Folder and file names become visible eventually which may be all that is needed to identify data that you can delete on the system to free up space. It is alternatively possible to zoom in our out with the mouse wheel.

A right-click on a file or folder opens a context menu with additional options. Here it is for instance possible to open the folder in Windows Explorer or the file in the default program viewer, delete or move a file or folder, or open a command prompt window from the selected location.

FilePro has three additional modes that you can make use of. TreeSize displays all folders sorted by size from largest to smallest in a tree sized view in the program window. Here it is only possible to open the containing folder or a command prompt window.

The Folder Statistics mode displays root folders and the space their files occupy in the selected location. The visibility threshold can be modified to display a deeper structure.

File Statistics finally displays the largest files on the system, with options to filter the results by filename, directory, size or date.

System snapshots can be saved, and compared at a later point in time. It is further possible to compare directories, and to use FilePro to locate duplicate files on the system.

Command line options are available to create snapshots without starting the graphical user interface.

FilePro is a free for personal use. The program supports Windows 7, and maybe previous versions of the operating system as well.

How To Analyze WordPress Plugin Performances

I have been using WordPress ever since I started blogging here on Ghacks in 2005. It has been a pleasant ride most of the time, with the occasional rough bump down the road. As a WordPress administrator, you have access to thousands of different plugins that extend or improve the blog’s functionality. One issue that you may experience after installing plugins is that your site may load slower than before. Plugins can have an impact on the site’s load time, the server load and overall performance. The more plugins you have installed, the slower your site may become.

That’s a big issue in times where search engines are favoring fast loading websites. It also may mean that you have to upgrade your hosting to keep up with the performance requirements of your website.

P3, Plugin Performance Profiler, is a free WordPress plugin that analyzes the performance of frontend plugins. Frontend plugins are all plugins that are executed during page loading time.

Installation

Just open Plugins > Add New in your WordPress admin dashboard and search for P3. Click on the Install Now link to install the plugin, and on Activate on the next screen to activate it. You can alternatively download it from the official WordPress Plugin repository to install it manually on your blog.

Usage

Open Tools > P3 Plugin Profiler and click the Start Scan button to run the standard scan. The program will load several posts and pages from your site to calculate individual plugin performance data. You can alternatively run a manual scan instead, which allows you to pick the pages and posts that you want to load on the site. The benefit here is that you can specify exactly which posts and pages you want to use for the sample.

Once done, results are displayed in the program interface.

You should now see the average plugin impact on the site’s load time, the number of MySQL queries that are run per visit and a runtime breakdown by plugin.

If plugin impact appears to be to high, or if you have a plugin installed that is using a lot of resources, you may want to consider replacing it or removing it completely from the site. You can deactivate plugins before you run the test again to see if the deactivation has a positive impact on the frontend page loading times. You could furthermore install an alternative to see if it is lighter on the resource side.

There is however no option to compare scans with each other, which is unfortunately. It is also not clear why the performance profiler itself is listed in the results, as it does not really make a whole lot of sense.

Still, if you are hearing complaints from readers or are noticing server peak load times and resource usage, you may want to check out the Plugin Performance Profiler plugin to see which plugin may be causing it.
