When you display a file you will, by default, use the internal viewer which can specifically handle .html/.htm and .ico files. All other files are treated as simple text.
You can, however, configure external viewers to handle files with specific extensions. Under Windows, some common extensions, such as .pdf .doc .rtf .xls and .bmp are pre-configured for you.
To configure external viewers, use the Preferences/Viewer Preferences menu option. You can then map commands to extensions. When entering a command you can place it in double quotes if it contains spaces. The command will be invoked with the file you want to view as its parameter. You can also specify the actual position of the filename parameter by using %1
Windows Example
In a windows environment, you can specify that Adobe Acrobat Reader
is used to open pdf files by adding an entry to the Dialog box invoked
by Preferences/Viewer Preferences as follows
| "C:\Program Files\Adobe\Acrobat 6.0\Reader\AcroRd32.exe" "%1" |
However, if Adobe Acrobat Reader is already installed on your system, the above entry will be configured automatically the first time you run the JZip Windows Launcher.
