I want to show my windows/mac machine folder structure in a tree view. Is it possible to get the current machine folder structure and render it in tree view.
Do you want to get hacked, because that’s how you get hacked 
I am not sure 100% but I think that this is bigger issue than webix. It’s fundamental javascript issue.
What you can do is to use php or asp script to generate JSON array with folder structure, or you can prepare JSON with some stored procedure because it does not change often. It saves time. I have a special table called JSONTable where I store only calculated JSON for stuff that is not changing all the time. When user update or add something new, I save it in normal table but then I loop my JSON array with help of json2.js (I have asp page) and update it than save it again into JSONTable.
During the night, store procedure will recalculate again ending previous day. So only daily changes are updated which increases speed a lot.

Due to security reasons component can’t access the file system directly. So you need to have some kind of script that will read filesystem and provide json data for the components ( similar to one described above )
