什么是 .bak 文件?

A BAK file is a backup file, a copy of data created as a safeguard in case the original data is lost or damaged. These files are commonly created automatically by software applications as a safety measure during editing or before significant changes are made to a file. The content of a BAK file varies depending on the application that created it. It might contain a complete copy of a document, database, configuration settings, or other types of data. BAK files are not typically meant to be opened directly. Instead, they are usually renamed to the original file extension to restore the data. The process of restoring from a BAK file often involves locating the BAK file, renaming it to the original filename and extension, and then opening the renamed file with the appropriate application. This allows users to revert to a previous state of their data, effectively undoing any unwanted changes or recovering from data corruption. The presence of BAK files can be invaluable in preventing data loss and ensuring data integrity.
