Description
The bld file type is associated with MegaPaint, a bitmap graphics editor that was popular on Atari ST computers during the late 1980s and early 1990s. BLD files contain graphic data created and saved within the MegaPaint application. These files are used to store images, including the layout, colors, and other graphical information handled by the software. Given their specific association with MegaPaint, BLD files are primarily opened or edited with compatible software or emulators that can interpret the format.
