Set-up/Data Retrieval

Flo-Ware for Windows software is the user on-site set-up, data management, and report generation software. It is compatible with desktop/portable computers utilizing Windows 95/98/2000/Me/NT/XP. Flo-Ware FX for PocketPC has all the same functionality as Flo-Ware for Windows with the exception of report generation.
