.sto

Extension: PRO100 3D Interior Design Project

Developer: Ecru Software

The .STO file extension is directly linked to PRO100, a specialized 3D interior design software application created by Ecru Software. These files serve as the primary storage format for entire 3D design projects created within the PRO100 environment. This means a single .STO file can contain a wealth of information, encompassing detailed room layouts, precise furniture placement and dimensions, material specifications, lighting schemes, and even textures applied to surfaces. Essentially, it’s a comprehensive digital representation of a designed interior space, ready for viewing, modification, or printing from within the PRO100 program. Understanding this complexity helps appreciate the importance of properly backing up these files, as data loss would represent a significant setback in any design project.

Opening a .STO file requires the dedicated PRO100 software. It’s not a universally compatible file type that can be opened with generic image viewers or other CAD programs. To access and work with the contents of an .STO file, you must have PRO100 installed on your computer. Simply double-clicking the .STO file should automatically launch PRO100 and open the associated project. If PRO100 isn’t installed, your operating system will likely prompt you to select a program to open the file, but without the correct software, the file will remain inaccessible. Therefore, ensuring you have the correct version of PRO100, compatible with your .STO file, is crucial for viewing and manipulating your 3D interior design projects.
