SKB file format stores backup copy of 3D model created with SketchUp software. It contains a carbon copy of model data stored in original file. SKB file is saved in same folder as main file. SKB file is allocated to original copy of SketchUp file. SKB extension serves as backup in case original file gets corrupted or deleted.
To open SKB file, launch SketchUp and select “File” → “Open.” Navigate to SKB file location, choose it, and select “Open.” However, SKB files are not meant to be directly opened or edited by users. SketchUp manages this process in background to ensure data integrity and project continuity.
Main difference between SKB and SKP files is their purpose. SKP is original SketchUp file. SKB is backup copy created automatically when auto-save enabled. SKB allows restoring SKP file if lost, corrupted or accidentally deleted.
SKB files are created by Windows SketchUp as [filename].skb. macOS autosaves as [filename]~.skp. SKB files typically saved in “My Documents” with SKP file. Location can be changed in Preferences.
You may need to update SketchUp to open recent SKB files. Check SKB file for viruses by scanning with antivirus software. SKB files are most popular in United States on Windows 10. They are backup files for SketchUp models. If SKB file opens wrong program, re-associate SKB file type with SketchUp.
