## Open File

This function allows the user to select and load a local file from your computer in the following formats:

**project files (.dav, .dvp),**

**model files (.osgb, .obj, .stl, .ply, .fbx, .json, .gltf, .glb, .b3dm, .3ds, .dosgb, .mfb),**

**vector files (.kml, .shp),**

**image files (.tif),**

**LAS cloud(.las, .xlas).**

Users can open model files by browsing the file path or dragging and dropping the files onto the software interface.

## Open Folder

This function allows the user to select a folder containing **multiple OSGB files**.

The software automatically loads all supported files in the folder, making it easy for users to view and manage models in batches.
