Rename folders and add a tag suffix

Hi,

I want to rename the folder containing the mp3 files to [%year%] %album%.
e.g.: [2010] Recovery

So I made this action: Format value "_DIRECTORY": [%year%] %album%.
But the [ and ] characters aren't written! How do I fix that?

Another problem, I want my files to have ( ) around featurings.
e.g.: Rihanna - Love The Way You Lie Pt. 2 (feat. Eminem)

So I made this action: Replace "Feat." --> "(feat.".
But how do I get the ) character at the end of the field?

Thanks!

put them in single 'quotationmarks'
'['%year%']' %album%

$ represents the end of a line in regular expressions. So use:
Action: Replace with regular expression
Field: _FILENAME
Regular Expression: $
Replace with: )

EDIT:
a quick test showed that this gives you .mp3) which i don't understand since I thougt there is a difference between _filenam and _filename_ext.
Anyway, that makes it even easier. Use:
Action: Replace
Field: _FILENAME
Original: .mp3
Replace with: ).mp3

EDIT2:
for opening and closing bracket in one go:
Action: Replace with regular expression
Field: _FILENAME
Regular Expression: feat(.*).(...)
Replace with: (feat$1).$2

this time not only for .mp3 but for all filetypes with three characters in the file extension, represented by .(...)

Since Mp3tag v2.46c _FILENAME only includes the extension at "Replace with regular expression"

Thanks for the help guys!

ah, ok
that means the replace .mp3 with ).mp3 only works in in "Replace with regular expression" and not in "Replace"
