Database Location Path name?

[cpat]

Hello,

Just wondering can i use disk volume name "XYZ" instead of drive letter "E:"? Since my Sticky Password Database and Backups are on a USB flash drive.
Current Database Path: "E:\Personal\Encrypted\default.pws"
Current Backup Path: "E:\Personal\Encrypted\StickyP\"
I do not want assign a permanent drive letter for USB flash drive on my PC, because I use multiple systems daily and Portable Sticky Password is not an option since Database and Backup location Path are greyed out.

Thank's

Craig
