Blender Backup Format | Blender | Backup Files |
The BLEND1 file extension is used by the Blender 3D modeling program. It is a file format that stores complete 3D scenes, encompassing objects, materials, textures, lights and images. Essentially, it contains all of the information and data necessary to reconstruct any given scene in full. This ensures that files can be backed up easily and sent between colleagues without worrying about losing any work.
Technical Details
The BLEND1 file extension is saved in an open-source format specified by Blender. It uses ASCII-encoding and binary data to serialize data into its container, which includes .BLEND, BLENDS, and .BLN files. The header of the file uses a different ID when compared to .blend files to identify it as a backup file, along with the date and time when it was created. In addition to its main index for linking elements of the project together, the file may also contain an associative array of custom properties for each individual element.
Associated Software
The only software capable of accessing a.BLEND1 file format is Blender. As such, any attempts to open or edit such files must be done through this software. Other similar formats include .BLEND2, BLEND3, and BLENDX, which are all backup files from various versions of Blender.
Programs for WINDOWS system

Programs for LINUX system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BLEND1) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .BLEND1 extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .BLEND1 file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .BLEND1 extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .BLEND1 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BLEND1 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BLEND1 file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .BLEND1 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BLEND1 file) will be extended to the maximum.
It is also good to check
- if the .BLEND1 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
