Opening CAL files

Did your computer fail to open a CAL file? We explain what CAL files are and recommend software that we know can open or convert your CAL files.

What is a CAL file?

The .cal file extension is most commonly associated with scheduling and calendar applications. The CAL files contain the dates and events included in the calendar schedule and may also contain custom images for each calendar month.

The .cal file extension is also used for CALS Raster Group 1 image format files, CALS Raster Group 4 fax compressed bitmap files, CyberAudioLibrary link files, Daqarta extended audio data files and SuperCalc Worksheet files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
