Most files used by Magic Set Editor are stored in packages.

A package is either a zip file or simply a directory.

A package has an extension to indicate its type, for example "*.mse-set" is a set file and "*.mse-symbol-font" is a symbol font. To open a zipped package using a program like winzip you may need to rename it to ""


A package always contains a heirarchical data file with the same name as the package type and no extension. For example "my-set.mse-set" contains a file called "set".

A package can also contain other files like images.


The data directory contains packages in the form of directories. Each of the subdirectories is a package.
