Browsing a selected file must be initiated from one of the menus (Files->Browse), LMB double clicking the file, the Toolbar or Alt+B combination keys.
Fixed File Associations
Double clicking with the LMB (or keyboard Enter) on a .ZIP file causes the contents of the archived file to be listed in a ZipView Window. Support is limited to those files that are compatible with InfoZip's UNZIP.EXE and ZIP.EXE which must be available to FS/2 with the path to those files set in the External Programs page of the Settings notebook. FS/2 will find these files and enter them as appropriate in the External Programs page if they are in a path found in the SET PATH environment variable in the CONFIG.SYS file.
A LMB double click (or keyboard Enter) on a file with an extension of .INF results in launching the OS/2 VIEW.EXE utility to view the selected file.
A LMB double click (or keyboard Enter) on a file with an extension of .MET results in launching the OS/2 PICVIEW.EXE utility to view the selected file.
The VIEW.EXE and PICVIEW.EXE files must be in a directory included in the environment path (they typically are).
User Defined File Associations
User defined file associations may be set in the Settings notebook, Paths pages 3_2 and 3_3. When a file is double clicked on with the LMB (or keyboard Enter) and it does not have an extension that matches one of the fixed file associations noted above and is not an executable file, the user defined associations are checked for a match. If a match is found, that user defined program is run with the clicked on file as the command line argument.
Undefined File Associations
A double click of the LMB (or keyboard Enter) on a non-executable file with an extension not defined under the fixed or user defined associations will launch the browse program entered on the External Programs page (Path tab) in the Settings Notebook (defaulted to E.EXE editor) with the selected file as the program argument. The program may be set to test for an ASCII file by checking the Enable ASCII Filter in the Configure External Program dialog for the browse function. If this option is set, the browse program will only load pure ASCII files.
