What is a .STO file?

The .STO file extension is associated with PRO100, a software application designed for creating 3D interior design projects. This type of file, known as a PRO100 3D Interior Design Project file, typically contains a detailed layout of furniture and other interior design elements within a room or space. Users of PRO100 can design room interiors by placing furniture and decorations in a virtual space, and the software provides an instant 3D visualization of these designs. This allows users to see how a room will look before any real-life changes are made.

The .STO file includes all the necessary information for the design, such as the arrangement of furniture, choice of materials, and overall layout. These files are useful for interior designers, furniture makers, or anyone planning to renovate their home or office space. Additionally, the designs stored in .STO files can be easily printed, making it convenient to share physical copies of the design plans with clients, contractors, or team members.

To open a .STO file, you will need to use Ecru Software's PRO100 program. This is the specific software that creates and manages .STO files, and it is equipped with the tools needed to open, edit, and save these interior design projects. There is no indication that other software programs support the .STO file format, so PRO100 is essential for working with files of this type.
