What is the file format of bak, how to open bak file?

.bak is a backup file, which is a file format extension. These files are usually preceded by .bak and should have the original extension such as windows.dll.bak or windows_dll.bak, while others are from the original. The file suffix name is mixed with bak. For example, the backup file of proteus is .DBK. Many software, such as editplus, will automatically generate its backup file after it has generated a certain type of file. If you don't want to back up the file, you can open the tool->gt.--->File on the menu bar. Cancel the "create backup file automatically when saving" & rdquo; before the hook is canceled, other software such as CAD, KEIL and other software can also cancel the default backup file through the relevant settings.

How to open bak file?

Generally speaking, a .bak file can be restored by directly renaming bak to the format of the file and opened normally.

For a simple example: sometimes the .bak file will be generated when the autocad file is moved. For example, there is now a backup file asdfjk.bak for the asdfjk.dwg file. You only need to restore the backup file to an official file. Renaming the backup file can be opened by replacing bak with dwg.

Similarly, if it is a backup file of the word file, just replace bak with doc. (can be changed to any file format)

Also, encrypted .bak files cannot be opened by modifying the rename, which is also garbled. -------------------------------------------------- -----------------------------------------
