Rename files and folders, even with profiles and with undo, using Bulk Rename Utility
Although ignorant persons claim the opposite, there is no real alternative to applications such as Microsoft Office. You can not have a freeware for anything, unless you are willing to sacrifice important features. This is not the case with Renaming tools. Along with PFrank and Metamorphose, the Bulk Rename Utility can be considered one of the very best.
Bulk Rename Utility has evolved through a series of user-requests, one-off requirements, and general enhancements. The program is rather complex according to the wealth of options that it provides, but it’s not difficult to use. The program renames files, folders or both, it supports string substitution, Change of case, Removal of characters or words, digits or symbols. It can append or prepend text, append dates in several formats, append the parent folder’s name, auto-number files with flexible rules, automatically preview the new names, Group configurations into “favorites”. “Bulk Rename” Explorer extension is very convenient. You can also rename files from an input text-file list, create an “Undo” batch file, log activity.
