### Setting TQSL Options

To inspect or change TQSL's options, select the File menu's Display or Modify Preferences... command (on OS X, select the Application menu's Preferences command) to display its Preferences dialog; this dialog's Options tab provides control over several settings that govern TQSL's operation:

- Enable automatic Backup File creation on termination
- Open ADIF files in ADIF editor
- Display status messages in a separate tab
- Enable passphrases for Callsign Certificates

##### Enable automatic Backup File creation on termination

If you want TQSL to automatically create a Backup File when it terminates, check the Allow automatic configuration backup box, click the Browse button to the right of the Backup File Folder textbox, and use the Browse For Folder dialog that appears to select the folder in which Backup Files will automatically be created when terminating. The most recent Backup File created on TQSL termination will be named `tqslconfig.tbk`. TQSL will automatically retain the number of previous Backup Files specified by the Number of Backups to retain setting, deleting the oldest Backup Files in excess of this setting. Retained Backup Files will include the date and time of their creation in their filename.

##### Open ADIF files in ADIF editor

If this box is checked and TQSL is started with a command line that specifies a file with an .ADI extension but does not specify -q or -x switches, then TQSL will display the contents of the specified ADIF file in its ADIF Editor instead of signing the contents of the ADIF file; if this box is not checked, then when started from a command line that specifies an ADIF file, TQSL will always sign the files contents.

##### Display status messages in a separate tab

With this box unchecked, TQSL displays status messages in a Status Log pane below the three Log Operations, Station Locations, and Callsign Certificates tabs:

Enabling this option and then restarting this TQSL adds a fourth Status Log tab to the right of the other three. This enables more Station Locations and Callsign Certificates to be visible without scrolling:

Any change to the Display status messages in a separate tab option will take effect after TQSL is next restarted.

##### Enable passphrases for Callsign Certificates

If this box is checked, when a user creates a new Callsign Certificate, they will be prompted for a passphrase to protect that file. This option is not recommended unless the Callsign Certificate is stored on a shared computer system.
