FileMonkey

File Monkey is a useful application that automates common file management tasks like copy, move, split, search, replace, rename, alter case, list or delete duplicate files, trim, truncate, crop, chop, set attributes, etc., making it easier for you to perform those tasks for batches of files allowing you to save a lot of time.

Some of the tasks this application performs are the possibility to edit file contents (append data, change capitalization, encrypt files, search and replace), rename files, change file attributes, copy or move files, create custom batch files, change file date and time stamps, delete files, extract text, find, join files, list, split and wipe files.
FileMonkey presents a simple interface (might take some time to get used to all its features) and offers lots of tools administrators will find useful (especially the command line for batch jobs). If you want to test this software, a free 30-day trial is available for download.
Supported operating systems:
