PFrank (Peter1s Flexible RenAmiNg Kit) is flexible file renaming tool that enables you to rename your files using simple or complex renaming schemes. You can add incrementing number counters, prefixes, postfixes and more. The software supports meta data for audio, image, video, email, office, and markup-language files, and can extract the information to be used in the new file name.

PFrank includes a set of pre-defined renaming commands that can simply be selected from a drop menu, and the results can be previewed before any changes are made to the actual files. Advanced users can build any renaming sequence they like using pre-defined or custom commands in combination with regular expressions. PFrank is very flexible when it comes to custom renaming options, but it also requires some dedicated involvement with the configuration and documentation.
PFrank also supports a built-in command line interface (with all the renaming power of the GUI), renaming of Subversion controlled files (only available from SoftSea.com web site), and Unicode.

PFrank Features:
* Pre-Defined renaming commands for:
* changing case,
* inserting counters,
* inserting parent folder names,
* eliminating whitespace sequences.
* inserting file properties,
* inserting tag information and meta-data from Music files (e.g. MP3, Ogg Vorbis, FLAC),
* inserting EXIF tag, IPTC tag, and meta-data from Image files (e.g. JPEG, TIFF, GIF, etc.),
* inserting meta-data from Raw Image files (e.g. CRW, NEF, DNG, etc.) is supported via a plugin,
* inserting tag information and meta-data from Video files (e.g. MPEG, AVI, etc.),
* inserting tags from Markup Language files (e.g. HTML, SGML, etc.),
* inserting meta-data from e-mail files (e.g. Mozilla EML),
* inserting meta-data from Office type files (e.g. Word, Excel, Powerpoint, etc.),
* inserting information from text files,
* inserting hash codes,
* Powerful Regular Expression (regex) based search/replace engine for defining custom replace commands. Regular expressions are a standard language. With PFrank there is no need to learn any custom or non-standard languages or syntax. With regular expressions it is trivial to add/delete/replace text or move/swap any parts of the filename.
* You create the expressions or choose from dozens of pre-defined regular expression sequences that you can modify as required.
* Define any number of search/replace regular expressions and then run them in a custom sequence with one command!
* Include any of and as many of the pre-defined renaming commands in the custom sequence!
* If the pre-defined commands and regular expression ability can't do what you want, then develop your own commands using the full power of the python programming language! See here for details. These commands, once plugged in, are treated like any of the built-in pre-defined commands.
* Save custom sequences into a list. Any number of lists can be saved. A list manager is used to manage the lists.
* Regular expression flags are available to ignore letter case, ignore file/folder name extensions, control the number of replacements made, and more!
* With the Path Builder feature you can create a folder path from the current folder to a renamed file. eg.
* With the Grouping feature you can apply renaming criteria obtained from one file to to also rename files that are in the same group. e.g. insert meta-data from a .jpg file and insert it in the name for the .jpg and the corresponding .crw file
* Highly customizable Music renaming. Eliminate extra whitespace, have consistent case (also define list of exceptions for words that are to have specific case), have consistent bracketing, consistent delimiters, consistent quoting, and more. With one command, all your MP3, Ogg Vorbis or FLAC file names can have the same naming format.
* The performance is highly optimized for very large numbers of files/folders.
* Preview changes before you make them. The Advanced scanner highlights any problems that would occur from the renaming including duplicate names, illegal characters, missing tags, and names that are too long. After previewing, you can edit or remove selected entries.
* Manually edited names are highlighted.
* The Previewer has many columns of information any of which can be enabled/disabled, resized, configured to be temporarily hidden, moved to different positions, or sorted. You can specify if you'd always like to see the rows sorted by the same column. Sorting can be in regular character-based order or in numeric based order (sometimes called natural sorting). Rows can also be moved up/down individually or in groups or can be arranged in random order.
* The Previewer includes a built-in thumbnail viewer for image or text files.
* If you've specified insertion of counters in the names, and you don't like the order that the names were numbered, you can use the row sorting or row rearranging features of the previewer to list the rows in the order that you want, and then reapply the numbering.
* Drag file/folder names into the preview window.
* Automatic resolution of duplicate names is optional.
* Recursively processing the contents of subfolders is optional.
* Variety of options available for filtering names before applying the renaming scanner. You can filter names by using:
* Patterns (can also exclude names based on patterns),
* Minimum length of name,
* Maximum length of name,
* Minimum length of pathname,
* Maximum length of pathname.
* Last Modified Dates.
* You can use patterns to include subfolders and their contents (can also exclude subfolders and their contents based on patterns) and can limit the level of subfolders processed.
* Regular expressions can be applied in the name filter pattern to specify any name combinations to include in the scans.
* Regular expressions can be applied in the name exclusion filter pattern to specify any name combinations to exclude in the scans.
* Apply renaming to only files, only folders, or both files and folders.
* Apply renaming to the entire name or just the prefix or extension.
* Pre-Defined commands to change letter cases can be customized to specify a list of words that will always be forced to a certain case regardless of which type of letter case command is used.
* Pre-Defined commands to insert counters are highly customizable. You can choose minimum and maximum lengths, start value for numbers, amount to increment numbers, padding of zeros, different number bases, and the use of random numbers.
* Number sequences can be restarted in each subfolder.
* The same counter values be used for names that have common prefixes but different extensions.
* Pre-Defined commands to insert music, image, video, file properties, or other meta-data are highly customizable.
* When inserting date information you can format the information using any combination of month, day, year, day of week, hour, minute, or second. You can also add offsets to any of the date/time fields.
* Plus there are many more configurable options!
* You can add text to the comment frames of MP3/EXIF tags. The text can include the original file name.
* You can change file properties such as the last modification date, creation date, last accessed date, read/write attributes.
* Unicode Support.
* Regular Expression previewer.
* Open files before renaming. Display picture files in a resizable thumbnail before renaming.
* Rename Subversion (SVN) controlled files
* Undo your last change anytime (even after restarting) or configure capability to undo all renaming operations.
