如何从 linux 服务器上的大 (30Gb+) zip 文件中提取文件

Question

1) extract from large zip file

I want to extract files from a large zip file (30Gb+) on the linux server. There is enough free disk space.

I've tried jar xf dataset.zip . However, there's an error that push button is full , and it failed to extract all of the files.

I tried unzip , but zipfile corrupt.

Archive:  dataset.zip 
warning [dataset.zip]:  35141564204 extra bytes at beginning or within zipfile
(attempting to process anyway)
error [dataset.zip]:  start of central directory not found;
zipfile corrupt.
 (please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

I tried zip -FF dataset.zip --out data.zip , and there's an error that entry too big:

zip error: Entry too big to split, read, or write (Poor compression resulted in unexpectedly large entry - try -fz)

Is there anyway I can efficiently extract files from really large zip file?

2) extract certain files from a large zip file

If I only want some certain files from this large zip file, is there anyway I can extract only these files? For example, data1.txt from dataset.zip? It seems that I can't use any zip or unzip command (always have the zipfile corrupt problem).

Thanks!

Answer 1

I've solved the problem. It turns out to be a zip corruption problem. I first fixed the file with:

zip -FF filename1.zip --out filename2.zip -fz

then unzip the fixed zipfile:

unzip filename2.zip

and have successfully extracted all the files!

Many thanks to Fattaneh Talebi for the help!

Answer 2

you can extract specific file from zip

$ unzip -j "zipedfile.zip" "file.txt"

file.txt is the file you want to extract from zipedfile.zip

Answer 3

try extracting directories to retain control and know where you left off. eg: tar tv --wildcards -f siteRF.tar './Movies/*'

Answer 4

I had the similar kind of problem and it got solved by unar command.

unar file.zip

Answer 5

I tried all the steps mentioned above to unzip the file, but failed miserably.

My last resort was to copy my zip file (11.1GB) into a hard drive and unzip it using 7 zip on Windows 8 OS.

Worked like a charm :D

Answer 6

I also solved it in similar manner like Irene W did. It was a corrupted zip. I first fixed the file with:

zip -FF original_corrupted.zip --out fixed_file.zip -fz

then unzip the fixed zip file:

unzip fixed_file.zip
