Re: Sync files between Windows Installation and mobile app
A .sh3x file is almost the same as .sh3d file: both are based on .zip format except a .sh3x file doesn't contain a Home entry which requires Java to be read, and a .sh3d file saved with Sweet Home 3D older than version 5.3 doesn't include a Home.xml entry required to be read by Sweet Home 3D Mobile, programmed in JavaScript and not Java.
More quickly said, if you use only Sweet Home 3D 5.3 or a more recent version on your desktop computer, you don't have to care about .sh3d or .sh3x formats, both will work the same.

If you want a smaller file on your desktop computer, use File > Save and compress menu item.
ZIP, SH3D and SH3X files can be compressed at a level from 0 to 9. Sweet Home 3D File > Save menu item saves a file at level 0 (not compressed but faster), whereas File > Save and compress menu item saves a file at level 9 (best compression but slower to save). Sweet Home 3D Mobile exports a .sh3x file with a compression level 5, which generates quite quickly files already well compressed.
