I wrote my first tutorial here and wanted to add an attachment with all files necessary for running the sample. In total it was as zip of 541kB. But the forum told me, the file size is to big.
Now my questions:
What is the current maximum file size for attachments here?
Is it really contemporary to limit attachments at such a low size?
Is'n it better to have the files here, that on a third party cloud? a external link may break in some years...
Do you have example projects with source code in your zip file?
If yes, I suggest you to remove the Objects folders from the projects, they use much space and are not necessary.
This is not just a workaround suggestion and not an answer to your question.
