search all folders, and copy files with a matching text string (regardless of file ext) into a target folder.
I'm looking for a bat file or macro to run through an existing excel or text file listing around 57000 numbers (which consist of both numbers and text). Find the corresponding files which contains an identical text string (but which may have additional characters in the string at the end not limited to the file extension). The search function should search all sub folders within an identified root folder. The identified files should then be copied (not moved) to an identified target folder.
