This file is saved in a binary format, which requires a specific program to read its contents.


Automatically generated backup file created by Blender, a free 3D modeling program; stores a copy of the previously saved version of the currently opened .BLEND file; used for recovering the previous version of a BLEND file; can be renamed with the ".blend" extension and opened normally.

More Information

BLEND1 files may be accompanied by other ".blend2," ".blend3," etc. files. These files are generated based on the number of allowed save backups the user specifies in the application preferences. Note that ".blend2" is an older version of the Blender file than the ".blend1" file.
