UNIX for Dummies Questions & Answers

Hi all
While unzipping files in linux i am getting error as:

Archive: mdxcopy.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of mdxcopy.zip or
mdxcopy.zip.zip, and cannot find mdxcopy.zip.ZIP, period.

Can anyone guide me on this.
Also i have read other threads regarding this but they have not helped me much.

The problem is when i am taking that zip into my windows machine it is getting unzipped properly and i am able to retrieve all data, but when i am trying to unzip on the Linux server it is throwing me the above error.
Please help.

TIA

Perhaps you need to update your version of unzip.

Also, run file on that file in case it's anything weird.

what is the extension of your zip file? coz in linux zip files extension is like .gz also... if not there is an option by right clicking on the file like 'extract here'.. try with this..

Hi amisubha the error got resolved.. actually i was trying to extract a blob and i didn't knew in which format it was stored.. i was trying to retrieve it in ZIP format and then tried to extract. but actually it was stored in GZ format in the blob.. after trying all the possible file formats to extract i was successfully able to retrieve it and gunzip it..

Thanks

hmmm gud.. .gz file can be unzipped by tar command.

Incorrect, .tar.gz can be unzipped by tar, but not plain .gz

Running file on the file would have told you what it was without the guessing.
