【Daily Question No. 006】January 6, 2019: In Auto CAD, a bak file is generated automatically after drawing. What is the purpose of this file? Backup of the current drawing
A bak file is a backup file generated automatically by CAD, intended to prevent unnecessary losses caused by accidentally deleting the original file.
It’s a backup file; to prevent the original file from being accidentally deleted, just change the file extension from bak to dwg
A bak file is a backup file. Bak backup files can prevent losses caused by various unexpected factors.
This is indeed a backup file; when you open a CAD file, the system automatically creates a backup version of the original file and saves it in the current directory, with a .bak extension. When you close CAD, if no changes have been made to the file, that backup file is automatically deleted; if changes have been made, the backup file remains (it will automatically overwrite the previous backup file) ； Its purpose is that if you make a mistake and change its extension from bak to dwg, it allows you to restore the file to its state before your last modification.
