Hi!
I don't think this good to have space in directory (nor in file name) due to url writing standard to be WC3 :
www.w3schools.com/tags/ref_urlencode.asp
Quote: "URLs cannot contain spaces"
Images downloaded in iCagenda are encoded in WC3 standard, but it can't renammed your directory.
If an extension allows space in names, they're wrong!
Try to create in Joomla media manager a folder with space, you will have this error message :
Message
Unable to create directory. Directory name must only contain alphanumeric characters and no spaces.
And if you have an error message from iCagenda, this is normal
I really recommend you to use standard naming for your repository!
