Here are some key features of “Rename Expert”:
Simultaneously rename folders along with subfolders and files
Allows the batch renaming of any number of files and folders in one go (incl. network support).
Icon filter

Filter and sort functions
The extensive filter and sort functions can also be used for metadata, allowing the inclusion and exclusion of files and folders.
Icon CSV files

Use CSV files for naming
CSV files – for example, exported from Excel, can be used flexibly for naming files and folders. The old and new name can be composed of several columns.
Icon move files

Move and rename files in one step
In addition to renaming, files can also be moved or copyied into subfolders whose naming is based on metadata (e.g., picture taken date, creation date, etc.).
Icon special functions

Many special functions
Rename Expert offers a variety of specialized functions, such as adding the checksum (MD5, SHA, CRC32) of the file contents to the file name, the encryption of folder and file names, or the possibility of adding random characters to file names as well as to rename files completely random.
Icon preview new file names

Real-time preview of the new file names
All changes are shown in real-time and are checked for errors (e.g., duplicate name) to avoid possible conflicts.

Rename files using numerous metadata
Metadata (EXIF, IPTC, ID3, etc.) can be used for the naming of files (e.g., for images and audio files).
Icon numbering files

Numbering of folders and files
Files and folders can be numbered sequentially or in random order. An existing numbering can be easily overwritten or adjusted.
Icon file content

Create file names automatically from file contents
With Rename Expert you can automatically generate file names from the file contents of documents (e.g., XML, HTML, or log files).
Icon rename file extensions

Rename file extensions
With Rename Expert, file extensions can be arbitrarily changed (e.g., jpeg to jpg). They can be added or removed, and their case is individually customizable.
Icon path too long

Shorten long file names / Edit file paths with more than 260 characters
With Rename Expert you can rename files or folders that exceed a path length of 260 characters, and therefore can no longer be edited using Windows Explorer.
Icon use profiles

Save rename-settings as profile
Action lists allow a combination of any different number of actions and can be saved as profile for future reuse.
