F2 is a Windows program that provides an automated way of renaming
batches of files. I wrote it after needing something to rename thousands of mp3
files - I tried about 5 or 6 different renaming programs, but they all seemed
to be designed to do a different task than the one I wanted to do.

If you want to know why it is called F2, select a file in Windows Explorer,
and then press the F2 key.
How to Use
Coming soon... :-)
Regular Expressions
In order to support regular expressions, F2 uses the open source C++ library
boost regex++,
which is part of the boost library.
If you want to know about the regular expression syntax accepted by regex++ (and hence
by F2) then read this web page
from the regex++ documentation.
The syntax is pretty 'standard', however, as a brief summary:
- Character classes work as you would expect, e.g.
- Tagged expressions should be contained in parentheses, e.g.
This would allow you to use
%1 and %2 in your
renaming scheme, and they would be replaced with the matched part of the
filename.
- Don't forget to escape 'special' characters with a backslash, e.g.
\(This is in brackets, and is not a tagged expression\)
So, say for example, you have a collection of mp3 files that are named using
the following general pattern:
Artist - Album - TrackNumber - Trackname.mp3
so, for example, you might have:
- Erasure - Wild - 01 - Piano Song (Instrumental).mp3
- Erasure - Wild - 02 - Blue Savannah.mp3
- Erasure - Wild - 03 - Drama!.mp3
- Erasure - Wild - 04 - How Many Times.mp3
- Erasure - Wild - 05 - Star.mp3
...and so on, and you want to rename the files so that you have a folder for each artist,
and a sub-folder within that for each album, and in that album folder are
the mp3 files of the tracks from that album. But you only want the mp3 files
to be named using the track number and name.
In this case, you would use the
following regular expression to match each of the filename components:
(.*) - (.*) - (.*) - (.*).mp3
This would get you 4 tagged expressions (%1 through %4), which you can then
use to rename the file. In our example, we would use this as the new filename
pattern:
If you used F2 to rename using this scheme, our example files would end up
in a nested folder hierarchy, as follows:
- Erasure
- Wild
- 01.Piano Song (Instrumental).mp3
- 02.Blue Savannah.mp3
- 03.Drama!.mp3
- 04.How Many Times.mp3
- 05.Star.mp3
Issues
The program has a few rough edges which I'll try to fix soon. In particular, at the moment the
checkbox for enabling mp3 tags has no effect (the tags are always read and used if
you use any mp3tag keywords in your renaming scheme).
It should run on Windows 95 upwards, but so far I have only tested it on Windows 2000 and Windows XP.

Acknowledgements
Many thanks to:
- Yoz Grahame for various cool ideas about how to make F2 cool and
super powerful, most of which I have yet to implement. But I'll try.
- Sean Sollé for endless nagging about improving the UI, and
making absolutely everything update in the background, thus simplifying the
UI and removing many buttons from the dialog. As
Jason Williams
once said, "It's a lot easier to know which button to press when there's
only one button."
- John Maddock
for the regex++ library, which saved
me a ton of work, and has so far worked flawlessly (although I would
like to bend his ear sometime about copy constructors that throw exceptions...
hhhnnnnggg!)
- Dirk Mahoney and the other developers at
id3lib.sourceforge.net for the id3lib code,
which F2 uses to read ID3 tags from mp3 files. They also saved me a ton of work
and allowed me to add a nice feature to F2.
