..t..WamingKmm::hThe Krunch command consolidates unused space on a disk. You use thiscommand when you run out of space or seem about to because the unusedspace on the disk is fragmented. Using the Extended directory list commandwill show you how the unused space is distributed on the disk. AfterKrunching, all the unused space will be together at the end of the disk(unless you specify another location).This command requires that you type a disk volume name or number. Thespecified volume must be on line. To avoid writing files over bad areas ofthe disk, you can perform a bad block scan of the disk before Krunching. Ifbad blocks are found, they should be fixed or marked beforeKrunching. See"Disk Upkeep Commands" later in this chapter.As each file is moved, its name is displayed on the screen. IfSYSTEM.PASCAL is moved the system must be reinitialized.IDo not touch the RESET key, the power switch, or the disk drive dooruntil Krunch informs you that it is finished. Otherwise you may make theinformation on your disk inaccessible.ExampleSuppose you type K because you wish to Krunch the system disk:Prompt: Crunch what volume ?Response:"You could also have responded with the volume number, #4, or the volumename of course.Prompt: From end of volume, block 28fl ? CY/10Typing v initiates the normal Krunch. Typing N elicits the questionStarting at block # ?If you type a block number in response to this prompt, the•Filer will attemptto make room for new files in the area surrounding the block number thatyou specified. It does this by moving files forward (toward lower blocknumbers) that are below the specified block, and moving files backward(toward larger block numbers) that are above the block. The feature allowsyou to rearrange files by placing them somewhere other than the end of thedisk.IBy the Way: If you specify a Krunch starting block that is within anexisting file, but the Filer tells you the disk is already Krunched, try astarting block in the filewith the next higher block number.Il-56Chapter 3: The Filer
