I note that 'workingDirectory' is the directory where Pharo is
launched from. In my case it happens to be the same where the image is
in but that cannot be assumed generally.
The fact that "workingDirectory" point to the folder from where Pharo was launched is only valid since Pharo 7. Before there was no distinction between workingDirectory and imageDirectory which caused problems when you wanted to script.��
So
�� �� (FileSystem workingDirectory / '..' / 'public') ensureCreateDirectory
Worked fine.
Thanks to all!
