I want to create a regex to help me parse a series of filenames that might look like, for example:
/a/b/c/d/e
/x/y/z/a/b/c/d/e

[download]

where I want to extract only the last 3 components of the file name
ie c, d, e and f

I thought this would do it as it was pinned at the end (using $) and I had minimised the greediness of . (using .?)
-- I have added "\.([a-z0-9]+?)" to the end to pickup files with a suffix --
/\/(.*?)\/(.*?)\/(.*?)\.([a-z0-9]+?)$/i

but for some reason it picks the wrong components.
For example, if I have
/x/y/z/a/b/c/d/e.f

I get
$1=x
$2=y
$3=e
$4=f
