Defraggler options - Advanced tab

Shell Extension
Shell Extensions extend the abilities of Windows Explorer. If this option is enabled, a Defraggler menu will be seen when you right-click on any file or folder. This menu is created by adding a shell extension to the system. For more information, how to use shell extension, go here.

Windows Disk Defragmenter - Disk Defragmenter is the standard defrag tool that comes with Microsoft Windows.

Defraggler works much faster than its built-in counterpart and has many more features. There’s a quick defrag mode, and a mode to defrag only free space. You can also defrag specific files and folders.

When you check Replace Windows Disk Defragmenter, Defraggler will open instead of Windows Disk Defragmenter.

1. Check whether Replace Windows Disk Defragmenter option is checked in Settings > Options > Advanced tab and close Defraggler.
2. Go to My Computer.
3. Select any drive and choose in context menu Properties > Tools tab. A dialog will appear.
   
4. Click Defragment now... . Notice that main window of Defragggler appears.

Minimize to tray – Allows Defraggler to be minimized to tray. When minimized the following options are available in the Defraggler Tray Menu:

• Defrag system drive – runs a standard defrag on the system drive
• Quick Defrag system drive – runs a quick defrag on the system drive
• Close program after Defrag – closes Defraggler after defrag is completed
• Showdown after Defrag – shuts down your computer after defrag is completed

Advanced users can save all of Defraggler's settings to an external INI file by selecting Save all settings to INI file. This is useful for controlling Defraggler's options through batch files.

Folder entries
NTFS file system uses special index files to identify folders. These files are hidden and contain information such as filenames, creation timestamps etc. These index files are usually located in the MFT (resident). However if the folder contains a large number of files the index file will grow too big to be stored in the MFT and will moved to another location  the hard drive. If these files are moved out of the MFT they can be fragmented just like any other files which may cause performance issues for viewing folders with a large number of files in them.

There is an option in Defraggler (Settings > Options > General > Show folder index entries in the file list) which causes these files to become visible and therefore allows them to be defragged. Please note that sometimes Windows can put a lock on an index file which will prevent the defragmentation process.

Show cleanup drive prompt before defrag – If this option is enabled, you will be asked whether you want to empty Recycle Bin before defragging. You can also turn off the display of the confirmation box.

Cache analysis data of multiple drives – Remembers the analysis data of all analyzed disks. You can analyze more than 1 disk and then switch between them to see the results. If this option is unchecked, once you switch to another drive, the analysis results of the previous one are lost. This however means that Defraggler will be less memory consuming.

Use custom fragmentation settings – Excludes files: restore point files or/and hibernation files from defragmentation.

Stop VSS when defragmenting NTFS volume – This option disables Volume Shadow Copy Service and Volume Snapshot Service whilst defragmentation is running. After defragmentation is complete, VSS is restarted.
