You should use the COMP command to compare contents within two files or sets of files. This command compares the content in a byte-by-byte manner. You can use various parameters, such as /D, /A, /L or /C, with the COMP command to display differences or comparisons between files.

 

You should not use the XCOPY command to compare contents within two files or sets of files. This command is used to copy files, subdirectories or directories. You can use various parameters, such as /P, /C, /V, /Q and other parameters, with the XCOPY command to have more copy options.

 

You should not use the ATTRIB command to compare contents within two files or sets of files. This command is used to change the attributes of a file from the command line. It can be used to remove an attribute, such as the system attribute, by typing ATTRIB with the -s switch.

 

You should not use the EXPAND command to compare contents within two files or sets of files. This command is used to open .cab files. For example, the driver.cab file, where drivers are stored, can be accessed in this fashion to replace a corrupt system driver.
