What does DIR B mean?
DIR B is an abbreviation for “directory block.” In computing, a directory block is a unit of storage allocation for files and folders. It is essentially a segment of a storage device that is set aside for use by directories and their contents.
When a computer is booted, the operating system will scan the storage devices attached to it for designated directory blocks. Once it finds a block that is designated for directories, it will create a new directory and copy the contents of the block into it.
The size of a directory block varies depending on the operating system and the type of storage device. However, it is typically in the range of 512 bytes to 4 kilobytes.
In some cases, a directory block may not be large enough to store all of the files and folders in a directory. When this happens, the operating system will create a new directory block and copy the remaining files and folders into it.
DIR B is also the name of a command-line utility that is used to create, delete, and manage directory blocks.
