zipsplit

Zip split is some weird utilty that splits the file into parts (like the split command).

Splitting a file

Simple command interface

zipsplit -n 1024 Large.zip

Will split the file Large.zip into 1024 byte chunks.

Reassembling

This seems more complex than is you used split.

Make a Large file

Like split - cat it all into one file

cat img.zip.0* > img.zip

Fix the file

Not sure why this is needed but it is.

zip -FF img.zip --out img_fixed.zip
