I need to identify the whether a particular zip or rar file is splitted or not.

Is there any library to deal with archive file in java?

  • ZIP is in the standard API package java.util.zip. Maybe it throws an exception, when an archive is splitted or corrupt. For rar files i don'T know. – Andreas Aug 28 '12 at 10:33
  • Do you know whether you're specifically talking about split or spanning zips/rars? Or do you need to support both? – Vala Aug 28 '12 at 10:37

Usually multivolume RAR Files will follow the following name convention:

somefile.part01.rar
somefile.part02.rar
somefile.part03.rar

Or, using the older naming convention, like this:

somefile.r00
somefile.r01
somefile.r02

For Zip files: A split archive with 20 split files the files are typically named (replace ARCHIVE with the name of your archive) :

ARCHIVE.z01 
ARCHIVE.z02 
... 
ARCHIVE.z19 
ARCHIVE.zip

Note that the last file is the .zip file.
