Does the filename matter when you find duplicate files?
Duplicate files are files that are identical in content regardless of filename. It’s possible for them to have the same or different names.
When you manually search for duplicate files, some filenames can give you a hint. For example, duplicates created by copying and pasting are likely to have the word “copy” in the filename. These filenames are easy to sort and spot in a file manager app such as File Explorer, and such duplicates are somewhat easy to find.
When you use the best duplicate file finder software, the filename doesn’t matter or help at all. Such a piece of software uses hashing algorithms (e.g. MD5) or other algorithms to compare files and identify the duplicates.
When a human being identifies duplicate PDF files or photos, he or she will look at the filename and size and view the files in a PDF or image viewer. To make the identification, a duplicate file finder will check the hash value, size and file type or the hash value only (but not the filename), which is automatic and fast. This is why it is quick and effective in finding differently named duplicate files.

When you find duplicate files with different names but same content, you can do it by hand or using a duplicate file finder. The latter is recommended due to its efficiency, effectiveness and accuracy.
