I have a collection of many different backups over the years in 3 different hard drive and a myriad of folders in each (100s). Some of them are many multiple incremental backups. A few years back I bought Duplicate Cleaner Pro 4 to take on the project but it's been daunting. Someone somewhere suggested first I should consolidate all the data into one place and create folders by file type and move each occurrence of file type into their own folder - which I thought an excellent suggestion. Last year I bought a 4TB drive which will allow for such consolidation. Then I can use Duplicate Cleaner from there.
What I am looking for is software that given many tree branches will go through all subfolders and completely reorganise the files, moving all files of the same type to a folder. I am looking for software that would do this / allow rules to be written in to achieve this.
