What is a BK1 file?

Bk1 file extension has Autodesk Backup file type, developed by Autodesk, which is associated with the "backup files" category.

These are backups files created by some products from the Autodesk family: AutoCAD Map, AutoCAD Mechanical, and Mechanical Desktop. BK1 files are in fact .BAK files that got automatically renamed when one of the mentioned Autodesk programs crashed. BAK files are also created automatically when user decides to save his drawing files. When your session terminates unexpectedly due to an error, Autodesk software renames a saved BAK file and makes it a BK1 file, so the broken drawing file cannot replace the original backup. If there is already a BK1 file in the folder, Autodesk will use the ".bk2" extension, then ".bk3", and up to ".bk9". The same rule applies for ".bka"-".bkz" and ".baa"-".bzz" extensions.
