bug#32721: error with gzip 1.3.12

[l***@bnpparibas-pf.com]

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

I don't know of any such bug. gzip is regularly used on files larger than 130
MB, so it's not merely a question of file size.

That being said, ".zip" is file extension extension normally associated with
some program other than gzip, so I'd try the other program.

Hi Paul,

Thanks for answering.

It works with unzip instead of gunzip -dS ".zip" which is the command I use for the other files.
Does this mean that compression mode is different between this file and the others ?

Evidently. Sorry, I don't use unzip and don't know how it works.
