How to split a 9GB .zip file into smaller pieces?

grumpyskeptic · 05-09-2019, 12:24 PM

The file is my collection of old public-domain Windows programs. I could manually un-zip it and then re-zip it in parts, but that would take a long time.

Is there a quicker way to do this please?

I would like each part to be say 2GB. I recall in the past seeing zip files that were sequentially numbered but behaved like one big file.

Thanks.

You can use the split utility and then recombine the files using the cat command.

The split utility will create numerical or alphabetical suffixes.

Update. linux does have a zipsplit utility that will split an existing zip file into smaller parts. Never mind it might not be able to handle large files.

split to break up the file then cat to put it together should work fine

split to break up the file. You can use cat in *nix to combine them. Or copy for windows land.

C:> copy part01/b+part02/b+part03/b parts.zip

$> cat part?? > parts.zip

Having had to send a file like that over dialup and with email clients limited to 10MB attachments. Glad those days are over for "most" of us.
