Instead of displaying all of the lines that are different, fc displays only the first and last line for each set of differences. Compares the two files in binary mode, byte by byte, and does not attempt to resynchronize the files after finding a mismatch.
This is the default mode for comparing files that have the following file extensions:. Compares the files in ASCII mode, line-by-line, and attempts to resynchronize the files after finding a mismatch.
This is the default mode for comparing files, except files with the following file extensions:. Sets the number of lines for the internal line buffer to N. The default length of the line buffer is lines. This command allows you to switch to another directory or folder. Example: The following example switch to the parent directory:. This command is a synonym for CD. This command allows you to search for errors on hard disks.
Example: The following example scan the C drive:. This command allows you to delete all the content on the screen. This command allows you to change the background color of the current console. Example: The following example change the color to White on Blue:.
This command allows you to compare the contents of two or more files. Example: The following example compare the contents of file1. Example: The following example display the department variable:. This command allows you to check if a file exists. This command allows you to ends a batch file or command prompt. This command allows you to creates a for loop that polls the commands one after the other at the frequency indicated in parentheses.
You can use this tool to display any lines from two files or two sets of files that do not match up with the others. There is only one parameter you will need to specify, but you will need to enter two instances of it. This is the Pathname parameter in which you will state the location of your files.

Before we get started, you should download our three sample text documents which we will use for the test. These documents each contain a paragraph of text with a few similar word groupings. Once you have downloaded these three documents, you can copy them into any folder on your computer. For the purposes of this tutorial, we will put all the text documents on the desktop.
Now you will need to open up an elevated command prompt window. Now that you have your command prompt window open and you have your text files on your desktop, we are ready to do a simple file comparison.
In this section, we will do a basic comparison, and then add a few different options. Files are too different. Try changing the numbers or editing the files yourself and play with the file compare tool to see what results you get. As you can see from the image above, FC reports that no differences were encountered.
If you were to edit one file, add a single letter, and try the command again, your results would show up as in the image below. Scenario 4 — Perform a binary comparison of two different files and two identical files.
You will notice that the function begins by informing you that the two files are being compared. Next, a bunch of binary digits scroll by, which is where the files are being compared, side by side, and lastly, you receive a report that says that, FCexercise is longer than FCsample.
