Frequently Asked Questions

1. What is the purpose of a .BAK file in AutoCAD?
A .BAK file serves as a backup for your AutoCAD projects. It stores all the changes made to a drawing since the last save, allowing users to recover their work in case of file corruption or unexpected closure.

2. Can I open a .BAK file in other software besides AutoCAD?
Although .BAK files are primarily designed for AutoCAD, certain third-party tools may allow you to extract data from them, but the best practice is to use AutoCAD itself for proper recovery.
