WinCatalog 2024 Duplicate File Finder is the most effective way to find duplicate files on all your disks (hard disk drives, external disks, DVDs and any other data storage devices).
WinCatalog duplicate file finder allows to remove duplicate files.
First WinCatalog will scan your disks and create a catalog of files.
Using WinCatalog duplicate file finder you will easily find duplicates in a catalog of files in two ways:
1. Finding duplicate files by matching one or more fields.
Sort search results by a desired column - duplicate files will be shown together.
2. Finding duplicate files by a checksum.
Calculate the checksum for files while scanning disks and then find duplicate files (e.g. duplicate pictures, duplicate photos, duplicate mp3, etc.) by a checksum, even if files have different names.
WinCatalog duplicate file finder implements both the typical search algorithm using simple queries and the advanced search using logical operators AND, OR, parenthesis and quotes - it makes the search more precise and provides for exact matching catalog search results.
Besides finding duplicates, you can organize your catalog of files, using tags (categories), virtual folders and user defined fields, and find files in seconds, using advanced powerful search, even without inserting or connecting disks to a computer.

"Excellent program for indexing all the files across the PC and external and backup drives. Makes keeping track of everything and finding where things have been stored just so much easier. Found photos and files I didn't realise I still had. Also great for finding unneccessary duplicates and freeing up disk space."
"WinCatalog is blazingly fast, especially when thumbnails and such are turned off. An 8TB disk with 110,000 files took me less than a minute to catalogue. It is also easier to use than the others I have looked at. It also handles thumbnails well, if you need them. This rating went from a previous 4 to a 5 when I found the "duplicates" search function."
"So far, it has done everything I thought I needed to do with my collections, but having it to play with, has opened up other possibilities. Like the very quick duplicate finder, I needed to come up with lists of files of indentical size that may or may not be dupes, names have got various prefixs added which made simple sorting useless."
