Content creation

I've been searching online for a while but can't find any info to help me.

Can I upload any type of files to H5P from other content creation platforms?

For example, if I can get a zip or .txt file of content, can I upload it to H5P or is that impossible?

Hello to everyone,

I want to combine different drag and drop events to be done consecutively.

When first drag and drop  activity is finished, I want to switch to another drag and drop activity (different background, different elements).

How can I do it?

Hello,

im a freshman in H5P utilizing in Moodle. I've created a security course with several slides. Is there a way to ensure that every slide was viewed?
The thing is, that user aren't aware that there are more slides than one because of the "next" button in Moodle on the bottom right corner. People will click next (because people are used to it, they continue here) without recognizing the arrows below the slides and skip. I want to prevent this. Is there a way?
