Issue: Compress in unix server and FTP to windows and open the compress file using Winzip

sakthifire · #1 (**permalink**) 3 Weeks Ago

Hi All !
We have to compress a big data file in unix server and transfer it to windows and uncompress it using winzip in windows.

I have used the utility ZIP like the below.

zip -e <newfilename> df2_test_extract.dat

but when I compress files greater than 4 gb using zip utility, it produces error.

Please suggest me for my requirement.

That's because of a limitation in the ZIP format specification (see Info-ZIPs FAQ). The algorithm ZIP uses uses 32bit pointers, which limits the file size to 2^32 Bytes, or 4 GB.

Is ther any alternative way to follow other than ZIP utility for the requirement?

You can use zipsplit

or gunzip (man gzip)
