Zip file can not decompress Mac OS X

[torbachkristensen]

Hello DB.

I have now, on multiple occasions, had clients write me that when they download a folder I sent them, the resulting .zip file will provide an error when decompressed. I have myself recreated this on a Macbook Air M2 on OS X Monterey and Big Sur. The downloaded zip file has the correct size, but is corrupt. 

Best, Tor

Hey @torbachkristensen, thanks for reaching out to the Dropbox Community today.

Which browser are you using to download the files? 

Do you see any difference, if you download them from a different browser or a private browsing window?

And do the files preview correctly on the Dropbox website?

Keep me posted.

I don’t know what browser clients use, but for me it is Safari. Everything is perfect in my dropbox folder and the web interface. It is only the server generated zip files that get corrupted.

Hi @torbachkristensen, how large is the zip file once it is compressed and downloaded?

[torbachkristensen]

Different. Between 100 and 400 mb. 20 files max.

Hi there @torbachkristensen, sorry to jump in here.

Out of curiosity, could you try another 3rd party app for unzipping/decompressing the zip files you mentioned?

Hi @Walter,

How long will take to your developers to fix this old bug instead of advice to "try 3rd party app for unzipping/decompressing"? 🧐 Yes, it's likely some app can do the trick. It's clear that in some cases (not always) Dropbox makes folders letter cases mismatch. While this isn't typically a issue for systems (like Windows) where paths are not case sensitive, for most other systems (not only Linux and Mac) it can be an issue (like discussed here)! 🤷😡

Remind to your system developers/designers to fix this.
