Shell Extension and Thumbnails

 

 

Evaluation note:

 

When in the evaluation period the MysticThumbs logo is overlaid on generated thumbnails.

After registering the product those thumbnails with logos need to be refreshed either manually using the shell context menu or by clearing the entire thumbnail cache from the control panel.

 

 

Operation

 

Thumbnails are automatically generated for supported files by Explorer when required. If the file doesn't have a thumbnail or the file's modification date is newer than it's thumbnail then a new thumbnail is requested by Explorer.

 

Windows Explorer is responsible for storing and managing all retrieved thumbnails. MysticThumbs supples Explorer with thumbnails when required and delivers the generated thumbnail based on the following heuristic. (Example uses the .psd file extension as an example):

 

Does MysticThumbs handle the image file type (.psd extension)?

Is the file type enabled in the control panel for the given extension (Photoshop Document).

Is the file extension enabled in the control panel for the given extension (.psd).

Does the file pass the size requirements, if assigned, for the file extension in the control panel.

Generate a thumbnail based on the given file type settings (Photoshop Document).

Override file type settings with any file specific settings set by overriding with the Explorer context menu.

Apply adornment and other extension specific settings to the image thumbnail such as transparency options.

 

Thumbnails will be generated in all Explorer windows, including Open/Save windows within applications.

 

Small icons will be generated if enabled in the control panel for icon views in programs that represent a file by its icon.

 

 

Automatic Refresh

 

When you save an image it's thumbnail is automatically updated by Explorer.

 

 

 

Enabling / Disabling

 

Individual file types or extensions can be enabled or disabled in the control panel if desired.
