CHKDSK (2)

CHKDSK

The "hidden files" are your DOS system files. These show up on all DOS disks. "User files" are those that are listed when the DIR command is used.

The amount of available disk space is perhaps the most important line
in the report. This tells you if you have enough space on a disk for
continued work. If the amount of space is limited, it may be time to use
another disk, delete obsolete files to recover disk space, or copy
inactive files to another disk and then delete them from the current one.

Notice that the CHKDSK command also gives you a report on your computer's memory. The total amount of memory and the amount of free memory is displayed. In the first sample report, the system is using
41,520 bytes (or characters) of memory space. This is often called system overhead. The second example shows a substantial amount of memory in use by DOS and other memory-resident programs. Here, it
is probably advisable to deactivate memory-resident programs if you must run a large application program. As a precaution, memory-resident programs should be turned off in the reverse order of turn-on. Otherwise, you are likely to experience a system "crash."

CHKDSK /N-Displays each directory and file as it is encountered by the program. Also displays disk error information.

CHKDSK /F-Used to recover (or fix) disk space that has been. misallocated in the directory. Places recovered disk space into files and assigns filenames beginning with FILE0000.CHK,
FILE0001.CHK, and so on.

CHKDSK filename-Checks the designated file for continuity in the 23 it is arranged on the disk. Displays a message telling whether the file blocks used are contiguous.

CHKDSK .--Checks all files on the designated disk for continuity. Lists the names and number of non contiguous blocks for all files having more than one contiguous block.

FORMAT

The FORMAT  command prepares a new disk for use by organizing the disk into magnetic tracks and sectors that are readable by DOS. when a disk is formatted, any files on that disk are usually lost. because of the plethora of disk types and capacities, new parameters were added to the FORMAT command in DOS  version 4.01. MS-DOS 5.00 introduction a safe FORMAT command and the ability to UNFORMAT unintentially formatted disks. These parameters and others are presented in the following paragraph and table. FORMAT Command Form:   There are a number of FORMAT command forms. These are described in the following list. CAUTION  BE aware that the FORMAT command erases all files from the disk being formatted.     Many computer users  have accidentally formatted the wrong disk. If you have programs or    document files  you wish to keep, do not format the disk! (DOS 5.00 lets you UNFORMAT     disk, but even with this ve...

Filenames

It is important to understand DOS file naming conventions and their use. Here, filenames and some special filename "tools" called wild cards and literals are described. What is a File name?   Every program and data file is given a name to differentiate it from other programs and data files. A program is one or more computer instructions collected into a file. A data file is normally a collection of characters (or data) that make up a document, like a letter, or a database, like a collection of accounting transactions or customer records. Descriptive filenames are normally used. For example, if you create and save a letter to Mom, you might give it the filename MOM.LTR. A letter to Dad could be called DAD.LTR. A word processing program file might have the filename WP.COM. Examine these filenames a little closer. First, notice that each filename is meaningful. This is important if you want to know what is in a file by looking at its name. Obscure filenames are of little u...

CHKDSK

CHKDSK The CHKDSK command checks the status of a selected disk. It is an external DOS command, and it displays several information. These include: The total disk space The total disk space occupied and the number of files The total disk space either lost or considered unusable by the system The amount of disk space available for use The total amount of memory available in your computer The amount of memory occupied by the operating system and memory-resident programs The amount of memory available for use DOS Version 4.01 also displays the volume serial number, if one exists, and disk and memory allocation information. The general form of the CHKDSK command is:                                                        CHKDSK D: where D: is the drive letter holding the disk to be checked. For example, the command CHKDSK B: performs a d...
