We are trying to unzip a file on the zOS and the same error always occurs.

P083598:/u/p083598:>unzip /tmp/BM/NombresDowJones.zip
Archive:  /tmp/BM/NombresDowJones.zip                
  inflating: NombresDowJones.dat                     
  error:  invalid compressed data to inflate  

However apparently the file is correct ...

P083598:/u/p083598:>unzip -v /tmp/BM/NombresDowJones.zip                       
Archive:  /tmp/BM/NombresDowJones.zip

I tried to download the file to a Linux system (RHEL) and there the unzip works perfectly

Could it be due to the size of the file we tried to decompress (>4Gb)?
