bak is a backup file, which is 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 a mixture of the suffix name of the original file and bak, such as the backup file of proteus is .DBK.

Many software, such as editplus, will automatically generate a backup file after generating a certain type of file. If you do not want to back up the file, you can open it by opening Go to Tools->Preferences->File on the menu bar and uncheck "Automatically create backup files when saving".

Other software such as CAD, KEIL and other software can also cancel the default backup file through relevant settings. 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. To give a simple example: when autocad files are moved, .bak files are sometimes generated.

For example, there is a backup file asdfjk.bak of the asdfjk.dwg file. If you want to restore the backup file to a formal file, you only need to rename the backup file and replace bak. It can be opened as dwg. Similarly, if it is a backup file of a word file, just replace bak with doc.

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.

Computer backup file Ghost

The basic method of working of Ghost is different from other backup software. It is to copy a partition of the hard disk or The entire hard disk is operated as an object, and the object can be completely copied (including the object's hard disk partition information, operating system boot sector information, etc.), and packaged and compressed into an image file (IMAGE).

When needed, the image file can be restored to the corresponding partition or corresponding hard disk. Its functions include copying between two hard disks, copying partitions between two hard disks, copying hard disks between two computers, making image files of hard disks, etc. What we use more is the partition backup function.

In case of a problem with the original partition, the spare image file can be copied back. , let or partition return to normal. Based on this, we can use Ghost to back up the system and completely restore the system.
