I see from your previous questions that you know how to read in a list of files into an array. So I presume you're asking about the second bit, how to delete the last four characters from a string. For that, have a look at substr with a negative second argument. Of course, if my presumption is wrong, why don't post what you've tried so far?	[reply] [d/l] [select]

`@file_names = map{ substr($_, 0, -4) } @file_names; # alternativelly @file_names = map{ /(.*).{4}/ } @file_names;` [download]	[reply] [d/l]
