• Answer:

  I had a similar problem several years ago and used microsoft's LogParser to find duplicate files. Primarily designed for IIS, it also works on FS (File System). With Windows 7 it may be loaded already on your machine but a link is below. First step is to generate a list of all files (you can use extension filters) with their MD5Hash and FullPath, sort by MD5Hash, and output to a CSV file to bring into a spreadsheet or database. Find all the duplicate MD5Hash values in the sreadsheet, select one to keep and copy out all the FullPaths of those to delete. (The MD5Hash is not ***Perfect*** for this but is probably about 95%, or greater, accurate for determining duplicate files.) I then used simply put these into a batch file to "Delete D:\My\folder\MyFile01.jpeg". You can put any of these into a batch file. If you want a secure deletion use sdelete from the SysInternals page (link below). Just remember to add its path to the System Path so you can batch with it. You can also perform many other File System queries once you master the query laguage. There are all kinds of great sample queries in the Help file and link below. There are also many independent LogParser resources on the www. Good Luck
