@brunobottazzini The patch works fine w.r.t allowing spaces in project/file/folder names. But major problem is now it allows project/file/folder names to start with '.' (dot) which potentially erased 'demo' folder in my tests. We can put-up a regex based check before executing the create procedure.

@kamidipreetham good test case man!!!

I haven't thought on creating a file with . in front of it.

I will merge this patch and fix this issue in another PR

thanks
