Sweet Home 3D refuses to open a SH3D file I created, or opens it incorrectly. Is there a way to recover it?
When Sweet Home 3D saves a home, it attempts to create first a temporary file that replaces the previously saved file only once the temporary file is successfully created. This ensures that there's very little chance that your previous SH3D file gets corrupted even if the last save operation failed. Nevertheless some users still report they can't open their SH3D file. In case this problem happens to you, please try to describe to the developer of Sweet Home 3D the circumstances of the last save operation (was is successful?), whether the SH3D file was transferred or not by email, ftp or with an USB key, what happens when you try to open the file that causes problems, and join a compressed version of your SH3D file if possible. Finally, try next time to back up regularly your SH3D files, like you should do for any document you spend hours on.
