Hello
If I can export something (a project) to my computer by Menu / File / Download
how make the inverse : export something (a project) from my computer to my accompt ?
menu / File / Open gives not possibility of that…
What i miss ?
Thx by advance
Uploading/importing files
When you add a file, click on the big white rectangle at the bottom.
Downloading/exporting files
Click file and then download.
Yes, but I see you have “add folder” open at the same times so you will need to close that as it is overlapping.
Yes I thought that a new add will erase all was yet existing!
Seems if a file index.htm is yet existing , its name was increasing like index-1.html so a big mess 
So what i must make for import a new Project from my computer ?
Erase first one by one each file on the project folder ? Seems multiple selection is not possible…
I don’t see a Close function on the Web Editor…I surely miss another “hiden” little thing!
Sorry for these trivial questions but that is no simple like File / New, Save, Load, Import, Export, Close
And Daniel Shiffman has not detailed that on the Web Editor videos !
This medium post explains feature in the p5.js web editor: https://medium.com/processing-foundation/hello-p5-js-web-editor-b90b902b74cf. Check the explanation by Cassie Tarakajian.

Thanks : very educative but alas not about my specific questions!
She just says “Download on your computer as aspected” without details…
and erase files one by one…
Seems little short for my trivial problem!
