FCMP

Dedicated to advanced PC users who prefer command-line programs for rapidly performing tasks, FCMP is a small-sized tool that can compare two files by size, structure and contents. It can also compare two folders to identify duplicate and different files.

The syntax for this application is FCMP [/e#] [/f] [/ff"*.xyz"] [/i#] [/n#] [/nologo] [/nr] [/s] [/sdo] [/snp] file1 file2. To simply compare two files, all you have to do is write their names. Make sure to specify their paths too if they are in a different location than FCMP.

Our tests have demonstrated that the tool can see if a file is a prefix or suffix to another file, as well as if they are identical or distinct. If they are not the same, it reports back the offset where differences begin.

As far as the switches are concerned, you can use /e to end the comparison at any offset you prefer or /i to start it at any offset, /f to compare all files within two directories, or /ff to use filters. Console messages for folder comparison include the number of matches files, items with different dates, and files without counterparts.

The software application can be instructed to compare only a certain number of characters (/n), exclude recursion when it comes to subfolder comparison (/nr), suppress all output messages (/s), compare files only if they have the same date (/sdo), and exclude errors when files don't have counterparts (/snp).

The file offsets are 0-based. FCMP worked without errors on Windows 10 throughout our evaluation, remaining light on system resources consumption. Thanks to its straightforward syntax and intuitive commands, it comes in handy for all users looking for a fast solution when it comes to file comparison.
