The purpose of this program is renaming multiple files or folders (to keep them clean and properly sorted). It is an analogue of dialogues for replacing text in file, but in this case the replacements are made in filenames.

Features

• Simple and compact interface yet flexible replacements.
• Integrates with Windows Explorer:
  • Retrieves the current folder from the active Explorer window.
  • Or gets the list of currently selected files and folders from the Explorer window (to limit replacements only to this list).
• Supports drag'n'drop:
  • Drag'n'drop a folder to make replacements within this folder.
  • Or drag'n'drop a list of files and folders to limit replacements to this list.
• Filters the processed files and folders with wildcards.
• Supports regular expressions.
• Can append prefixes and postfixes to filenames.
• Performs masked numbering of files.
• And more...

Usage

Well, something should be already apparent from the above description and screenshot. But some additional explanations are surely needed.

First of all, how to start FileRenamer so that Windows Explorer remains active and the current folder is retrieved from it? Under XP you can create a shortcut to the program, place it on the desktop or into the start menu and assign a hotkey for this shortcut. Then, while working with files in Explorer you can hit this hotkey - FileRenamer will appear with the currently explored folder selected. On a pre-XP system you can use a master script for the same purpose.

Next, regular expressions can only be used in Find field. See quick reference on regular expressions. Replace field can include backreferences to captured subpatterns.

To number files you should include a number mask in Replace field. For example, [001] defines the following numbering: 001, 002, 003, ... And [00]: 00, 01, 02, ...

Fields All, Prefix and Postfix do the following:

• All replaces the entire filename with the contents of Replace. This only works with multiple files when Replace contains a numberer as described above. Contents of Find are ignored in this case.
• Prefix prefixes the filename with the contents of Replace. Contents of Find are ignored.
• Postfix postfixes the filename with the contents of Replace. Contents of Find are ignored.

Though using the program should not result in loss of data (files and folders are NOT overwritten)... The author is not responsible for any damage arising from the usage of this program. Use at your own discretion.
