Always show "Save As..."dialog box - with this option checked Dragster will display a Save As...dialog, allowing you to move a copy of the file and save it under another name. Otherwise Dragster will simply transfer the file - copying for remote destinations, and moving for local destinations - with the same name as the original.
Always replace existing files - with this option checked Dragster will automatically replace any existing files in the destination that have the same name. Otherwise it will ask if you want to replace the file on a case by case basis.
Make available to other Ambrosia apps - with this option checked Dragster's file transfer capabilities will be available to other Ambrosia applications that have this feature enabled.
