Banktivity saves the Banktivity Document (data) file in the Documents folder by default. You may be able to locate your Banktivity Document file in the Documents folder. Also, all Banktivity Document files have a .ibank file extension. You may be able to search for .ibank (use the dot) to locate your Banktivity Document file. Sometimes searching for ibank (without the dot) is helpful too.

If you were were previously using iBank 5, the same Document (data) file you were using with iBank 5 will continue to work with Banktivity 5.
