Autodesk AutoCAD Backup Format | Autodesk | Backup Files |
The BK1 file extension is associated with Autodesk Inventor, a 3D mechanical design, simulation, and engineering software developed by Autodesk. It an encrypted backup file that stores both 2D drawings and 3D models, created for later reference. The file can be opened by any version of Autodesk Inventor software installed in a supported computer system.
Structure and Format of the BK1 File Extension
The .bk1 files consist of data stored in an encrypted format that is not usually readable with text-editing software or programs other than Autodesk Inventor. They can be located in a variety of locations on a user’s computer, including hidden folders. The actual internal structure and components of the files are proprietary and may vary across versions of the software used to create them.
Files with the .bk1 extension are commonly exchanged between users who use various versions of Autodesk Inventor. Similar file extensions used for Autodesk Inventor include .iam, .idw, .ipt, and .dwg.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BK1) 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 .BK1 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 .BK1 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 .BK1 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 .BK1 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BK1 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BK1 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 .BK1 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BK1 file) will be extended to the maximum.
It is also good to check
- if the .BK1 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
