This dialog allows you to configure the settings used for the built-in file viewer. The settings are almost self-explanatory; just experiment with these settings as you use the Auto-view feature of the file list.
Keep viewer window always on top:
Check this option if you want the Viewer window always to be visible, i.e. not hidden by the main-window.
Use HEX-dump for unsupported file types:
This option allows you to see the contents of unsupported files (program files, database files, etc.) in HEX-dump format. Only the first 8 kb of the file will be shown, but it helps you to get some idea of the file's contents.
Auto-view files only if they are smaller than xxx kb:
Here you can specifiy if you want to limit auto-view of files to certain maximum file size. It speeds up processing when you browse the list of found files, but of course you will not be able to see bigger files automatically.
Use zoom-smoothing for images:
This feature applies to images only, and makes them appear a lot smoother. Otherwise, the images can be pretty ragged, especially if they are shrunk down from original size.
Auto-rotate images if they contain orientation info:
Check this option, if you want the built-in viewer to automatically rotate pictures that are taken in portrait mode. Of course the camera must support this option, and store the info in the image file.
Word wrap long lines in textual files:
Use this option to wrap long lines and paragraphs, so their contents can be viewed in the viewer window.
Show line number:
Check here if you want line numbers to appear in the left-side gutter, when viewing text files.
Use URL-highlighting for Internet links:
This option will make internet-links visible and active when viewing text files. Just double click on the link to visit the appropriate page.
