hi,
Some of my .wma files have Tags like this :
albumname[version]\version
I want to remove the last part beginning with the backslash, the problem is, that not all files have this format...
I`ve got this action :
field:
album
regex :
(.+?)[(.+?)]\\(.+?)
replace:
$1[$2]
but it does not work 
You could use something like this:
Action #1:
Action type: Replace with regular expression
Field: ALBUM
Regular expression: \\.*$
Replace matches with:
hmmm that expressions replaces all tags that include a backslash, some tags are like this : blabla/tatata/sdfsdf
they would be replaced too....
Change your expression to ^(.+?)[(.+?)]\\(.+?)$
