Hi, I work for BNP Paribas-Personal Finance (Paris - France) & report you following error : I try to decompress .zip file having size greater than 130Mb. I use following options : gunzip -dS ".zip" filename.zip I get following error invalid compressed data--length error For files having smaller size, it works fine. Can you please tell me this error is due to a bug or to used version 1.3.12 which does not support large files. Cdt / Regards Laurent GOURVENNEC DSI international - Projet DWH LISA (33) 1 46 39 13 07
