Hi Stefano,
this is the problem I saw too. My guess is that it is a simple encoding bug somewhere. But I do not have the time right now to investigate, unfortunately.

Dear Bert, I realized that I didn't check really everything. Indeed, I can open in ScratchJS projects that I created with Scratch 1.4, but I cannot reopen projects modified in ScratchJS, neither in ScratchJS nor in Scratch 1.4. I get the following error message in both cases:
Could not read project; file may be damaged (key not found)
Is this a known problem? Is there a way to overcome this limitation?
Thanks in advance
Cheers Stefano

Hi Stefano,
it is possible to export your project to your hard disk:
- run ScratchJS via https://squeak.js.org/scratch/#fullscreen
- 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: [image: image.png] 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!

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
Thanks for your help

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

?? ?? Dear All, I have two questions about ScratchJS (that I think is an awesome
project):
- is it possible to run ScratchJS locally? I tried to run index.html
in the SqueakJS-master\scratch folder, but I just got a black square in the upper left corner
- can I open local projects in ScratchJS?
Thanks in advance for your help
