FDUPES is a program that helps identify duplicate files within specified directories. Its various options allow the user to customize the search criteria and behavior of the program. For example, the ‘-r’ or ‘–recurse’ option allows the program to follow subdirectories encountered within the specified directories. The ‘-s’ or ‘–symlinks’ option enables the program to follow symlinks. By default, when two or more files point to the same disk area, they are not considered duplicates. However, the ‘-H’ or ‘–hardlinks’ option changes this behavior. The program also offers options to filter files based on their size, exclude empty or hidden files, and more. Care should be taken when using the ‘–delete’ option to avoid accidental data loss. The author of FDUPES is Adrian Lopez, and the software is protected under copyright laws.
