CCE File

What are CCE files and how to open them

Are you having problems opening a CCE file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CCE files.

What is a CCE file?

A .CCE file is a Calendar Creator Plus Project file.

Calendar Creator Plus Project files with the .CCE extension store event and scheduling data created by the Calendar Creator program from Spinnaker Software (formerly Power Up Software). These files contain one user's list of calendar events - appointments, holidays, birthdays, recurring events - that can be edited, formatted, and merged into printed calendar layouts. These files are used when designing calendars with customized appearance (fonts, colors, graphics) for printing.

Calendar Creator writes .CCE files when you save or work on a calendar "project" in its graphical interface; the file preserves both the event list and the layout/template settings until you print or export. Users can also export their events from Calendar Creator Plus into comma‐separated value (CSV) files if they need to exchange data with other programs such as Microsoft Outlook.

Technically, each .CCE file is a binary data file identified by specific byte signatures: it begins with bytes 0xFFCC at offset 0; contains the bytes 0x3A5C at offset 133 (representing the ASCII string ":\"); and includes the string ".CCE" somewhere in its data.
