DISKCOMP Windows command

The DISKCOMP command in Windows is used to compare the contents of two floppy disks. It helps users ensure that the files on both disks are identical. By executing the command in the command prompt, users can quickly identify any differences between the two disks. The syntax of the command is straightforward - simply type “DISKCOMP” followed by the drive letter assigned to each floppy disk. Additionally, users can add the “/1” parameter to disallow comparing the disks track by track, increasing the speed of the comparison process. Overall, the DISKCOMP command is a useful tool for users who work with floppy disks and need to verify the integrity of their data.

DISKCOMP Syntax:

Terminal window
diskcomp [drive1:][path1] [drive2:][path2]

Windows DISKCOMP Options:

OptionDescription
/1Compares only the first 512 bytes
/AForces ASCII comparison
/BForces binary comparison
/CCompares case-sensitive
/LCompares in ASCII mode by default
/NDisplays the sector number of any differences

DISKCOMP Parameters:

ParameterDescription
drive1Specifies the drive letter and colon of the first disk drive
path1Specifies the directory and/or file name of the first disk drive
drive2Specifies the drive letter and colon of the second disk drive
path2Specifies the directory and/or file name of the second disk drive

How to use DISKCOMP command:

Compare two disks

Terminal window
diskcomp A: B:

Compares two specified disk sectors and shows whether they are identical or different.

Compare disks with verbose output

Terminal window
diskcomp /v A: B:

Compares two specific disk sectors and displays additional information about the comparison process, such as the number of bytes transferred.

Compare disks and ignore size mismatch

Terminal window
diskcomp /1 A: B:

Compares two disks and ignores the size mismatch error if the disks are different in size.

Display help information

Terminal window
diskcomp /?

Shows the help information, which includes details about using the diskcomp command, its parameters, and examples.

Compare disks and list differences

Terminal window
diskcomp /l A: B:

Compares two disks and lists the differences found between them.

Selectively compare directories

Terminal window
diskcomp A:\folder1 B:\folder2

Allows for selective comparison of folders within the specified disks, providing information on any discrepancies found.

Compare disks and show progress

Terminal window
diskcomp /p A: B:

Compares two specified disk sectors and displays a progress indicator to monitor the comparison process.

Compare disks and force read-only mode

Terminal window
diskcomp /r A: B:

Forces the comparison of disks in read-only mode, preventing any changes from being written to the disks during the process.

diskcomp A: B: /T

What should I do if diskcomp shows differences between the disks?

If diskcomp shows differences between the disks, you should carefully review the output to understand the discrepancies in the contents of the disks.

Can I use diskcomp to compare the contents of a USB drive and a floppy disk?

Yes, you can use diskcomp to compare the contents of a USB drive and a floppy disk by specifying their respective drive letters in the command.
