PFrank is an acronym for Peter's Flexible RenAmiNg Kit. This is a Freeware Professional Grade bulk file/folder renaming program that runs under Windows. With this tool you can easily organize your music, picture, video, or any other types of files. PFrank comes equipped with many features, some of which you won't find on any other renaming program. The beauty of this tool is it's flexibility. You can easily build any renaming command sequence you like, preview all of the results, press the rename button, and you're done!
No other renaming program has the flexibility of PFrank!

With other renaming programs I used in the past, they always had to be run with multiple passes using different sets of renaming sequences until finally getting the required names. That was the motivation for writing PFrank. With PFrank you can set things up so that you get the exact names that you want in one pass!
If you are having trouble renaming your files then you could check out the Forums or contact me directly and I'm sure I'll be able to come up with a way to help you out.
In fact, I challenge anyone to come up with a reasonable renaming request that cannot be done with PFrank.
Unreasonable requests can now also be handled by PFrank! (click here for details)

The latest official version of PFrank is

PFrank has been continuously improved since its introduction in January, 2005. If you are using any releases before , then it would definitely be worth upgrading so you can take advantage of the latest features.

A new Forums site was recently made available! Previously email was used exclusively to answer questions about PFrank; Now everyone can share information and view answers using the forums.

There are many exciting features in the latest versions including a new plugin for insertion of meta data from raw image files (e.g. cr2, nef, sr2), a much improved undo facility, new filters, new positioning controls, the ability for users to plug in their own renaming commands, and much more! Recently added a custom list manager for managing any number of custom lists!
Many more improvements have been made in the last 2 years including the use of an original grouping feature, the selectability from dozens of pre-defined regular expressions (these can be used as templates for performing many renaming variations), the automatic display of columns depending on different criteria, a resizable thumbnail, a feature for custom building folder paths to newly renamed files (one of many features that were first available only on PFrank) , the ability to insert over 158 types of meta-data from music, image, video, email, markup-language, and other files. A sophisticated column manager was added to manage the potentially large number of columns that could be displayed in the preview window. Any of the meta-data can be saved to csv files!

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 Tucows web site), and Unicode. See the complete list of features here

Automated regression tests are used before every release to ensure that the core functionality of PFrank is reliable. Scanning and renaming is tested in folder hierarchies containing several hundred thousand files. The utmost care is taken to ensure that PFrank releases are of the highest quality.
