RemoveFileSuffix.remove_file_suffix(i) ↑

Class method here. The order should be kept, IMO. We get rid of the file suffix.

Note that .sub() for .tar should come after .gz and .xz, because .tar is typically coming before these two as well, such as in a “.tar.gz” file. Hence we first eliminate .gz in the following batch .sub listing.

Would it not be easier to just use File.basename() instead? We will try this since Jan 2014. Hmm nope, won't work.
