The CAL file type is primarily associated with XnView.

CAL	File extension: CAL
	File type:	monochrome bitmap image

What is a CAL file?

CAL files mostly belong to XnView by XnSoft. CAL is the filename extension of monochrome bitmap image files that are saved in CALS Raster Type 1 file format. CALS file format was developed by the United States Department of Defense to standardize graphics interchange. 3DS Max, a 3D animation software stores the pose adjustment values used to define the structure of a biped model in a CAL file. Calendar Creator, a calendar design software stores calendars (including dates, months images etc.) in CAL files. CryENGINE, a software development kit for creating 3D games stores a list of all animation asset files of a game character's animation in a CAL (Character Animation List) file. ArcGIS Pro, a GIS mapping and data visualization program stores SQL field calculations in CAL files. Music Creator, an audio recording software developed by Cakewalk uses CAL filename extension to save scripts written in Cal Actor Language.

How to open a CAL file

You need a suitable software like XnView to open a CAL file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CAL file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CAL file directly in the browser:. Just drag the file onto this browser window and drop it.

CAL file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the CAL files is as follows:

The CAL extension is very commonly used. This CAL file itself is among the most popular common file types and includes different formats for different programs. The file formats most commonly found in CAL files are:

65% of all CAL files are associated with CALS raster bitmap. If you open these files in a text editor, you will see only illegible characters. CAL files can be up to 3 MB in size, but are often around 30 KB - 470 KB. The file type was developed 20 years ago and is still in use today. Certain words are almost always found in the files, such as srcdocid: NONE dstdocid: NONE. Such files sometimes refer to plan, cals and type.
3% of all CAL files use the Microsoft Compound File format, which is also called Compound File Binary File format (CFBF or CFB) or OLE2 Compound Document format. This is a complex container format used by earlier versions of Microsoft Office and other Windows programs. Compound files always start with the bytes ÐÏà¡±á (hex code D0 CF 11 E0 A1 B1 1A E1). They consist of unreadable binary data. The average file size is 210 KB with most files being between 160 KB and 1 MB in size. Such CAL files store data about calendar and baby.

All the rest of the CAL files (32%) have different formats, often e.g. SuperCalc worksheet, Windows Calendar, QV Map Calibration data, SQL and Design. They are often associated with ambk, backup, folder, native, calibration, tiamat or base. If you want to find out what your CAL file contains, drag and drop it onto this page.

a cal monochrome bitmap image is a special file format by XnSoft and should only be edited and saved with the appropriate software.

How to solve problems with CAL files

Associate the CAL file extension with the correct application.
Update your software that should actually open monochrome bitmap images. Because only the current version supports the latest CAL file format. Search, therefore, e.g. on the XnSoft manufacturer website after an available XnView update.
To make sure that your CAL file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
