Some people have very specific needs when it comes to file renaming. Most of these needs can be accommodated with the power of PFrank pre-defined commands, regular expressions, and specialized commands. However, every once in awhile some one-of-a-kind, unique, or even insane request will come along that cannot be solved with the current version of PFrank and unfortunately is sometimes not general enough to be included as a standard feature.
These types of requests are no longer a problem!

The 'Plugins (or User Defined Commands)' feature allows anyone to develop their own renaming commands. The commands are written with the easy-to-use Python programming language and can be plugged in to PFrank enabling them to be used like any of the other pre-defined commands!

With plugins, you can now do any kind of renaming: How about rearranging the order of words in a filename alphabetically? applying mathematical expressions to numbers in a filename? changing the letter case of any part of the filename according to your criteria? importing metadata from obscure files? This is all possible! It doesn't matter if you are the only person on the planet who wants the feature; it can now be yours. This has to be the ultimate Power User renaming feature!

There is a simple and clearly defined application user interface that can be used to produce as many user defined commands as you like. A template file with sample commands are provided which you can use as a model. When the file is loaded into PFrank, each command will appear at the top of the pre-defined command list. Once in the list they can be inserted into the custom list like any other pre-defined command. If a standard Python modules need to be imported for your renaming and they are not already imported into PFrank it doesn't matter, you can import them yourself. With functionality like this the sky is the limit!

Some sample plugin files are below:

• Insert MetaData From Raw Image - Use this plugin to extract meta data from raw image files. PFrank currently does not support this feature directly because there are no open-source Python libraries that support this functionality. The plugin uses the command-line output of the freely available exiv2 program to rename files.
• Insert MetaData From Media files - Use this plugin to extract meta data from video or music files that might not be available with PFrank. The plugin uses the command-line output of the freely available mediainfo program to rename files.
• Insert Title MetaData From PDF files - Use this plugin to extract the meta data title from pdf files. The plugin can be used as a template to insert other PDF metadata.
• Add '1' to Hour - Use this plugin to add '1' to the hour field of files with timestamp information in their names
• Create Empty Folders - Use this plugin to create a set of empty folders before you start renaming. This was requested by several users.
• Insert File Content from matched Regex - Search for a string found inside the file using a regular expression. Insert that string into the location specified by the pre-defined renaming commands GUI.
• Capitialize Quoted Word - Capitalize the first letter of words that are enclosed in single quotes.

• Change Names to Alternating Case - Change name to have alternating letter case.
• Set Artist/Album Field - Use this plugin to change the artist and album field within MP3 tags of music files.
• Change Names to Counters - Change all names to a numbered sequence suffixed with a or b.

• Add 1.1 to first number - Add the number 1.1 to the first number that appears in a name.

• Reformat Date in a Name - Change the formatting of any date in a name to that specified by the PFrank 'Date Formatter' Option.
