DATAIR FlexPlus is an application for proposing, administering, and testing Flexible Benefit Plans. Its .ca files contain application data used by the software for these tasks.
The format is intended for the application's internal use rather than as a general-purpose data interchange format. The file should therefore be kept with the other data used by the relevant FlexPlus installation.
Use of the format depends on DATAIR FlexPlus. It is not expected to be useful as a standalone document or database file outside that application.
Open the file with DATAIR FlexPlus, using the application's own file-opening or data-management functions.
If FlexPlus does not recognise the file, use the copy associated with the correct FlexPlus data set and avoid editing or renaming it.
