I just noticed that, whereas Scratch manages quite well projects whose size is more than 250MBs, it seems that ScratchJS cannot load projects bigger than 20MBs. Is this a limitation that can be overcome? I'm very interested to it as my students are developping multimedia projects that require a lot of memory.
Cheers Stefano

Thanks a lot Bert! Everything worked as you described. It worked well in my "local" version too (that is the "run" page that I downloaded to my PC).
It would be very usefulif, when dragging the scratch.image to the box in the "run" page, Scratch would open in a new TAB. Is this an easy modification of the "run" page? Sorry if I ask you, I'm not an HTML/JS expert.
Cheers Stefano

Hi Stefano, it is possible to export your project to your hard disk: 1. run ScratchJS via https://squeak.js.org/scratch/#fullscreen2. Inside Scratch, click "Save" as you normally would, give it a name. I just did that and named mine "test".3. go to https://squeak.js.org/run/ and scroll down inside the file box: 4. click the "/Scratch/Scratch Projects/test.sb" link to download the project file.
To import an older project you simply drag-and-drop it into ScratchJS. Or drop it into the "run" page and then use Scratch's file dialog - you just need to navigate up to the right folder (Click "Computer" then "SqueakJS"):
When I just tested this it said the file was corrupted, not sure if that is a general problem or not. Someone should investigate - to get to the Morphic desktop, shift-click the loop in the R of the SCRATCH logo:
Feel free to file bug reports / feature requests at https://github.com/bertfreudenberg/SqueakJS/issues/ It would be relatively simple to make a proper stand-alone app out of this by packaging it via Electron, and using the actual file system instead of the in-browser file system. I just do not have the time for that currently. Cheers! - Bert - On Sun, Feb 9, 2020 at 7:32 AM David T. Lewis lewis@mail.msen.com wrote:
Hi Stefano,
I think that your understanding is correct. SqueakJS stores files in an internal database, so the Scratch files that you saved do not appear directly on your PC.
I do not know if it possible to copy those files to the file system on your PC, but hopefully someone on the squeak-dev mailing list will have an answer.
Thanks for asking, Dave

Correct. So that I can easily open my old Scratch projects and I can send projects that I develop in ScratchJS to other people
UPDATE: I created and saved a project in the "SqueakJS" folder (the one shown in ScratchJS) and I made a full search in my PC. The file was not found. So, I guess projects are just saved in an internal SqueakJS DB? If it is so, this makes unfortunately ScratchJS useless for my purposes. And I have no sufficient javascript/smalltalk knowledge to try myself to change this behaviour (that I guess would possible in principle, as a lot of JS apps allow to save file locally).
Cheers Stefano
I am also CC'ing the squeak-dev mailing list where some of the real Scratch and SqueakJS experts reside.
Thanks a lot Dave
I think that you are asking about running Scratch on Bert Freudenberg's SqueakJS, which is a modern Squeak virtual machine implemented entirely in JavaScript for HML5
Correct
If I understand your question correctly, you are asking about how to run Scratch on SqueakJS locally on your PC
Yes. I partially solved the problem by downloading page https://squeak.js.org/run/ and by dragging my Scratch.image file into the page. ScratchJS runs apparently fine. I also partially solved the problem of running local files, by dragging the Scratch projects on the Scratch app running in SqueakJS
you want to understand where the Scratch files are stored on your PC.
Correct. So that I can easily open my old Scratch projects and I can send projects that I develop in ScratchJS to other people

Hi Stefano,
I am changing the subject line to "SqueakJS for Scratch" because google sends me somewhere else for "ScratchJS".
I think that you are asking about running Scratch on Bert Freudenberg's SqueakJS, which is a modern Squeak virtual machine implemented entirely in JavaScript for HML5, rather than the traditional compiled virtual machines that run on operating systems such as Linux and Windows.
If I understand your question correctly, you are asking about how to run Scratch on SqueakJS locally on your PC, and you want to understand where the Scratch files are stored on your PC.
I do not have good answers to your questions but I am sure that others on this list can help. I am also CC'ing the squeak-dev mailing list where some of the real Scratch and SqueakJS experts reside.
Here are some useful links for SqueakJS information:

What I don't know is where the SqueakJS file system is stored. When I open the File>Open dialog I can see the SqueakJS and ScratchProjects folders. Where are they stored in my PC?
Thanks in advance
