By default, the file that saves the system options you select from one run of EZLease to the next (named Options.xml) is stored in EZLease's data folder (C:\ProgramData\LeaseAccelerator\EZLease for Windows Vista or later). You can move it to another location either by typing the path or by browsing to it (click the Browse button). This is primarily intended for EZLease users with multiple seat licenses, so they can share a common set of options. It can also be used by a single user to put it in a location that is more easily backed up.
