 File Format and Extensions

 

 

 

 Search for extension

When pressed a list of all supported file extensions is displayed in alphabetical order.

Use this button to select the appropriate file format and extension for a given extension.

When the combo box is visible you can begin typing the extension to search for and the best match will be selected.

 

 File Format Combo Box

Use this combo box to select the file format you want to adjust changes.

If an application is installed and assigned to the file type then its icon is displayed for each file type.

You can begin typing the name of the the format you want to find it.

 When in Apply to All mode this option is unavailable due to operations being carried out on all file formats. Instead a  warning icon is displayed.

 

 

 File Extension Combo Box

Use this combo box to select specific extensions for the selected file format you want to adjust changes to.

Each file format displays either its assigned override icon or the default icon for the file extension/type.

You can begin typing the the extension you want to find it.

 When in Apply to All or Apply to File Format mode, this option is unavailable due to operations being carried out to all extensions.

 

 

   Thumbnail Enable Button

Enable or disable MysticThumbs to act for this file extension's thumbnails.

Enable MysticThumbs to act for this file extension's thumbnails.

Disable MysticThumbs to act for this file extension's thumbnails.

Indeterminate - When multiple states exist in Apply to File format or Apply to All mode.

 

 Depends on Apply To Options check button.

 Disabling file extensions will prevent MysticThumbs from generating thumbnails and viewing them, and passes control back to any other thumbnail provider that was previously installed for them, or the system.

 

 

    Small Icons Enable Button

Enable this option to enable small icon thumbnailing for this file extension. Small Icon, List View and Details view modes that display using a small icon (usually 16x16) will also generate thumbnails and store them in the system icon cache. The system icon cache can be erased when using the Clear Thumbnail Cache option.

 Enable small icons. Thumbnails are created for small icons, list or details modes. This may slow down your computer depending on your hardware configuration.

 Disable small icons. Thumbnails are not created for small icons, list or details modes.

 Indeterminate - When multiple states exist in Apply to File format or Apply to All mode.

 

 

   Associate with MysticThumbs viewer (up to Windows 7 only, removed in version 4.3.0)

Enable to associate the MysticThumbs viewer to the selected file format extension(s). If enabled, when you double click on a file the MysticThumbs viewer will be used to open the file. This allows for very fast viewing of images using the MysticThumbs viewer.

 

 Compatibility note: This option is not available in Windows 8 and newer. Unfortunately (for better or worse) from Windows 8 onward, Microsoft introduced a private key signing system for the registry setting that controls which application opens a particular file format, presumably to prevent viruses and malware from manipulating some file formats from automatically opening with any given application unless the user manually chooses an application. This prevents MysticThumbs from assigning the QuickView tool as the default for any supported file formats. The workaround is to right click on each file you would like to open with the MysticThumbs QuickView tool and selecting the context menu option "Open with > Choose default program..." and selecting "MysticThumbs". This of course will be slow if you want to use QuickView as the default application for many file formats but will perform the same function as this control panel option.
