Update May 2017

A May 2017 Microsft security update for Windows 10 conflicted with a major routine in FileBoss resulting in FileBoss not starting on some Windows 10 systems.

Versions V3.101 and later, fix the problem. You can read more about this at the page

Installing & Using

Main Menu

(showing that the WordPad tool is active.
Select a viewer to toggle it on and off.)

Dynamically Associate Programs to Files

typically used display the contents of a file at runtime

Appear on Main Menu and Popup Menus depending

on where you decide they should go on a tool by tool basis

Will be available on the menus only

for the file type(s) you specify. Separate and multiple file masks can be specified for displaying each tool on the main menu (Tools > Viewers >) and for the right-click popup menu. This keeps the menus from being cluttered with viewers that are not relevant to the current file.

External Viewers (i.e. Programs) can be associated

with multiple file types and/or file specifications (e.g. *.BMP and S*.DLL)

Can be easily Enabled and Disabled

without uninstalling the Auto-Viewer by simply checking and unchecking check boxes.

Can be used to Search the Internet

for information on filenames or file types

Similar to External Tools

that are automatically called whenever a file of the correct type or matching the specified file mask is selected. To learn more about External Tools  Click here
