Those regular expression do not need to match the whole file, mine for
example are "_v[0-9]*\." and "." (a single dot). This way one can
insert a version between the file name and the extension and this file
is then recognised as new version of an old file.
(This is a little fiddly, it assumes that the filename has only one
dot in it, which is the case with my files.)

I was not aware of the regular expression supporting named groups, so
in this case maybe "(.*)_v[0-9]*\.(.*)" and "\1.\2" would work? (The
two "(.*)" each form a group of characters that can be accessed in the
second expression as \1 and \2. At least it seems that this is
possible from your example.)

Hope that helps,

Andi
