A simple split to two parts may not be enough depending upon the OP's filenames and how many '.' characters might be contained within those names. I think that a regex assignment would be more appropriate instead of a split. But it could be that this is all the OP needs.

That's why using File::Basename seems a good idea as it provides an easy interface to extract path, files-basename and extension.

    Yes, File::Basename is a fine idea. But that won't get you out of providing a regex in this particular situation. The functions either take a list of strings like ".txt". ".doc". Or a regex in qr// form. Of course the enumerated suffix strings are the easiest way to use these functions. However, in this particular situation with varying numeric suffixes, ".001", etc., I would think a regex is needed even if using File::Basename.
      File::Basename::fileparse can take a regex as an argument to extract the suffixes, so using qr/\.\d{3}/ will pick up the varying suffixes allright.
