I’m facing problems with the downloads of folders. Some are based on ZIP format (which works) and some of them base on TAR format (which doesn’t comlete the download and thus doesn’t work).
I can’t describe when the downloads create a TAR or a ZIP file, but in the meantime I found a way to open the TAR-files. So thanks for your quick feedback.
Years ago there were problems with ZIP and MacOS. Nextcloud has then probably decided on the basis of the useragent whether TAR or ZIP was used. But i don’t know if the problem has been solved. Can you set another useragent in your client e.g. browser? Maybe you can or have to disable the possibility of TAR somewhere in the source code. Sorry i do not use MacOS.
I think linux has not got the problem. There is also used TAR instead of ZIP. ZIP or 7-Zip is not standard there, too. But with linux the user was expected to take care of the ZIP vs. TAR problem himself/herself. Probably no one has ever bothered with the fact that files can also be automatically unpacked on the linux client.
