The Load branch under Configuration - File Handling has the following options:
Use default directory from shortcut on initial file open
Normally the directory used for the File Open command is the last directory that the editor opened a file from. This directory information is retained when the editor is shutdown and restarted. When the Use default directory from shortcut on initial file open option is set the normal behavior is overridden and the process default directory is used for the initial open. This allows the user to specify the default directory from the icon or shortcut that invokes the editor.
Use active file directory for file open dialog default
When this option is set, the normal behavior is overridden and the directory of the currently active file is used. This allows the user to easily open a file from the same directory as an already open file by activating the file and then use the File Open command.
Please note: Only one of the two items described above should be selected.
Open link (.lnk) files, not the file the link points to
This setting causes the editor to open the link for modification. The default setting (not setting this option) causes the editor to expand the link to open the root file.
Open files as read-only by default
The Read Only command toggles the state of the read-only status of the file. If the read-only status is set the file cannot be modified. If this is set, files will automatically be opened as read-only. This does not change the status of the file itself, just the ability to modify it within the editor.
Remember the read-only setting when reloading a file currently open
This setting causes the editor to maintain the Read-Only status of a file when this file is reloaded. By default when a file is reloaded the status of Read-Only does revert to the status of the underlying file. This is because a lot of users use this feature with version control systems and the only thing that changes is the Read-Only status and the users want/expect the status within the editor to change also.
