EES File Format
EES file format is the default format in which EES saves files. The standard EES file name extension is .EES, but EES can also store files in a compressed format that is represented with file name extension .EEZ.
The 64-bit license of EES saves files having an .EES64 file name extension or in compressed form with a .EEZ64 file name extension. These files are written in a different format than .EES files and they cannot be read by 32-bit EES licenses, even if the file name is changed to have a .EES file name extension.
