zipsplit size question

I searched the forum but seemingly the question previously posted is not related what I want to ask. So post my question here.

I list the zipsplit help and check on the internet (http://wiki.linuxquestions.org/wiki/Zipsplit)

It says that I can use

Code:

zipsplit -tn 100000 blah.zip

to split zip file with size specified. -t reports but doesn't create files.

However, when I try

Code:

zipsplit -n 100000 blah.zip

it always says

Code:

zipsplit warning: Entry is larger than max split size of: 99978
zipsplit warning: use -n to set split size
zipsplit error: Entry too big to split, read, or write (file.mp4)

What goes wrong here?

Or what should I do so that I can split zip file into several pieces?

Thanks.

I think I know the reason why now after reading this thread - https://lists.ubuntu.com/archives/ub...ly/152989.html

It looks like the file element can't be larger than the one specified by -n. There is only one file in my zip archive and it is larger than file size specified defenitively because it is video file.

Is there any chance to split zip archive regardless to the element inside it?

Thanks.

Only because it came up in my search for the same problem...

Thank-you for sharing the problem with zipsplit (I'm annoyed), here's what I was trying to replace

Code:

zip -s 64k -O split.zip pkg.zip

Will generate a number of files that are no larger than 64kb.

Reconstructing the data is apparently a little problematic since it's not really supported. The trick is to use the zip utility to merge all teh parts together, and then unzip the result.

Code:

zip -s- split.zip -O unpkg.zip
unzip unpkg.zip
