MyDefrag 4.1.1 introduces innovative, easy to use features to make your harddisk faster. It is freeware, with no time limit, and is fully functional with no advertisements. It is fast, with low overhead and many optimization strategies. It can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows. Included are a set of easy-to-use scripts for endusers, a scripting engine for demanding users, a screensaver, and a combined Windows plus command-line version that can be scheduled by the Windows task scheduler or for use from administrator scripts.

MyDefrag is extremely solid because it is based on the standard defragmentation API by Microsoft, a system library that is included in Windows 2000, 2003, XP, Vista, and 2008. Most defragmenters are based on this API, including the free defragmenter that comes with Windows and many commercial defragmenters. Basically all MyDefrag does is send "move this file to that location" commands to the API. The API is part of the operating system and can safely move almost any file on the disk, without risk and while the computer is in full use.

Defragmention: Imagine a book split into several parts, some pages are over here, other pages in another room on another floor altogether. You will have to walk a lot when you need to read the book. It may sound silly, but this is exactly what happens to files on your harddisk. Defragmentation will put all the parts (fragments) back together, making your computer a lot faster.
Optimization: Imagine a big library with lots of books, spread out all over the building and not sorted whatsoever. There is an index telling you exactly where every book is, but you will have to walk a lot when you need several books. This is exactly what happens on your harddisk, the files that belong to an application can be all over the place, anywhere on the harddisk. Optimization will bring all the files together in one place, leaving the rest of the harddisk empty, and will sort the files, for example alphabetically.

Defragmentation and optimization will not only make a harddisk faster, but also lengthen it's life span, because the disk will have less work to do and therefore have less wear and tear. Also, it will refresh and strengthen the magnetic data on the harddisk by simply reading the (weakened) data and writing it afresh. However, defragmenting and optimizing is work, so excessive defragmenting and optimizing can actually cause more wear and tear than it prevents.

Major Features:

1. On most harddisks the beginning of the harddisk is considerably faster than the end, sometimes by as much as 200 percent! You can measure this yourself with utilities such as HD Tune. MyDefrag is therefore geared towards moving all files to the beginning of the disk.
2. MyDefrag organizes files into zones, such as directories, Windows files, files used while booting, regular files, and rarely used files. The most accessed files are placed at the beginning of the harddisk, and files that are commonly used together are placed in close proximity to each other. This results in a dramatic speed increase, and is in fact more important than defragmentation. The program comes with scripts with a zone organization suitable for most users, power users can customize the zones through scripts.
3. Sorting the files on your disk can give you even more speed. There are several sorting strategies to choose from. Most of them will take a lot of data shuffling, taking a lot of time for MyDefrag to complete, and therefore should only be used occasionally.
4. A running computer will create and delete temporary files like there is no tomorrow. If the harddisk were completely optimized then the only place for new temporary files would be behind all the other data. Which is rather slow. MyDefrag can maintain free spaces at various locations on the disk to make temporary files faster.
5. Windows reserves a percentage on NTFS disks for the MFT (Master File Table), but can place normal files there if the rest of the disk is full. The files will remain there, even when there is enough space again. MyDefrag can look for files in the NTFS reserved areas and move them to normal diskspace, making the reserved areas available again for the MFT.

Enhancements:

• Optimized the subroutine that searches for contiguous fragments.
• Fixed a bug that would prevent the program from running (immediate finish) without a proper error message, if there was a directory called "Settings" anywhere in the path. Also added some extra error messages in case there is a problem executing a script.
• Optimized the subroutine that vacates items out of the way.
• Disabled the OtherInstances(ask) setting for the screensaver.
• The "F1" key now looks for the manual in the installpath, instead of always using "C:Program FilesMyDefrag v4.XManual.chm".

Requirements: Windows 2000, 2003, XP, Vista, 2008, and for X64.

StartDefrag can automate scheduling of HDD defragmentation on the Windows operating system.
The standard disk defrag software included with the OS does not support scheduling. Many Windows tips articles recommend defragmenting your hard drives regularly.
Note: Free for personal use
Main features:
- easy to install, use, and deploy within a business environment
- informative graphical user interface

Upgrade your hard disk performance and overall system speed by defragmenting your HDD with Puran Defrag The files saved on your hard disk may get fragmented due to various reasons. Due to this, while accessing the files, your HDD has to move a lot to get data from different fragments located at far distances, this will degrade your hard drive performance and overall system speed. In addition it results in high wear and tear of your hard disk and therefore small life.
Puran Defrag provides the solution. Puran Defrag is a very simple defragmentation utility which defrag the files that means it collect all the fragments of a file and puts them together, this upgrades your hard disk performance and thus overall system speed. In addition it results in low wear and tear of hard disk and therefore increases its life.
Advantages over other similar software
- Very high speed defragmentation
- In addition it can restart your computer with minimal resources and start defragmentation which adds to the speed.
- Once defrag is over, it can shutdown or restart your computer.
- It can defrag individual files by simply right clicking on the file and selecting Puran Defrag
- Even if a file cannot be defragmented due to low space, it tries to defrag it to atleast some extent.
- It performs a disk check before starting defragmentation after restart
- Command Line defrag supported
- Its Completly FREE
Version restrictions:
- For Windows 2000, it only works on volumes with cluster size not greater than 4KB, for others there is no problem.

DeleteOnClick is a very simple program that lets you securely delete files When you delete a folder or file using Windows, usually the file or folder is moved to the Recycle Bin (Trash). When the Recycle Bin is emptied, the data you have deleted is not actually removed from your computer. Instead , Windows makes the space occupied by the file available for writing.
In other words, every file you delete using Windows is potentially recoverable in the short term. If you create a new file after deleting using Windows, or save a changed file, it may write over the deleted files space, thus destroying it permanently. Likewise, defragmenting will possibly overwrite the deleted files.
DeleteOnClick completely deletes files in one click rather than sending the file to the recyle bin. The data becomes unrecoverable. For this reason you must use this program carefully. Once a file is Securely Deleted no one can undelete it.
