Linux made zip file not unzipping on Windows

[NMFTM]

I made an 8GB password protected Zip file on Ubuntu 10.10, sent it to a friend who's using Windows 7, and now she can't unzip it. The file transfer speeds between us are very slow, so I don't want to resend it. Every application she's tried (WinRAR, WinZip, and 7Zip) fails and gives some sort of "invalid archive format" error.

I had her do an MD5 checksum on the file and it matches mine. So, the likelihood of it being damaged during transmission is very small. I also successfully unzipped it on my end and used TeamViewer to try and get it unzipped on her end, just to make sure she wasn't doing anything wrong, she wasn't.

What could be the problem be UbuntuForums? Is there a difference in the way Windows and Linux handles zip files that is causing this problem?

Nobody?

You might want to check on how big if a file winzip can accommodate...there might be a capacity issue there.

Worth checking out.

Cheers.

If she was just using Winzip then maybe. But this is every application she's tried (except Unzip below) that's been giving her similar problems.

What is the exact command you used to create the .zip file?

I used the GUI. Right click -> compress -> selected .zip and set a password.

Here is unzip for Windows:

Thanks, I'll have her try this. Although I'm not sure why this utility would succeed where 7Zip, Winzip, Winrar, and Window's built in unzip feature have failed.

When you say sent, what method. How is your friend downloading the file.

TeamViewer's file transfer feature. But it shouldn't matter how I transferred the file because the checksums matched.
