bak file viewer

.bak is a backup file with the file format extension . This type of file usually has the original extension in front of .bak, such as windows.dll.bak, or windows_dll.bak. Some are mixed with the suffix of the original file and bak. For example, the backup file of proteus is .DBK.

Many software, such as editplus, will automatically generate its backup file after generating a certain type of file. If you do not want to back up the file, You can open Tools->Preferences->File on the menu bar and uncheck "Automatically create a backup file when saving". (Recommended learning: web front-end video tutorial)

Other software such as CAD, KEIL and other software can also cancel the default backup file through relevant settings.

Many software sets the creation of backup files as the default configuration of the software, especially many programming, drawing, and design software. The advantage of this is when the source file is accidentally deleted or due to a bug in the software itself When it automatically exits, you can continue editing on the basis of the backup file, otherwise the previous efforts will be in vain, thus reducing a lot of losses caused by misoperations.

Generally speaking, the .bak file can be restored by directly renaming it and replacing bak with the format of the file and opening it normally.

A simple example:

When autocad files are moved, .bak files are sometimes generated. For example, there is now a backup file of the asdfjk.dwg file. asdfjk.bak, if you want to restore the backup file to a formal file, you only need to rename the backup file, replace bak with dwg, and open it.

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

Also, the encrypted .bak file cannot be opened by modifying and renaming it, even if it is opened, it will be garbled.
