Ah, ok. It means if I do have some filename.py on my PC, via upload I can find it on a disk, and upload it to Thumby. Correct?

I cannot upload the code I made inside IDE directly to thumby. I need to do it via SAVE / SAVE AS
Is that correct?

Thanks a lot! Makes sense

However! I repeat, when I press the UPLOAD button it just OPENS A WINDOWS EXPLORER (I am on Win11 just in case) - and no upload is happening. When I use SAVE TO THUMBY or SAVE AS ...  - everythin's ok.

Strange.

Hi, I have just met Thumby and I was trying to follow the official tutorial from here https://thumby.us/Code-Editor/Get-Started/

Right from the scratch I do not understand the meaning of the UPLOAD button since it just opens an explorer and does NOT upload a "test.py" file to Thumby.
The only way to upload my code is via FILE --> save to Thumby. Then, everything is ok.

So what is wrong with this UPLOAD button?

Thanks a lot
