To avoid problems with renaming or moving files, all imported models and opened files are copied into temporary files or application directory.
So if you experience some problems when saving a SH3D file, I consider it as a bug and it should be fixed, except if you use some temporary files cleaner or you played with files in application directory.
- Under Windows, application directory is C:\Documents and Settings\user\Application Data\eTeks\Sweet Home 3D.
- Under Mac OS X, it's the subfolder Library/Application Support/eTeks/Sweet Home 3D of your user folder.
- Under Linux and other Unix, it's the subdirectory .eteks/sweethome3d of your user directory.
