    Hi Stefan

    KM Folders and files will accept special characters and automtically the id of it will

    be changed to _ on places of special chars like \ / .

    KM Property names definitely will not accept the white space in their ID.

    But there itself on the creation of it, the error message will throw up.

    So why do u actually want to know in advance?

      Hi Julian,

      "The KM UI uses display names, but this doesn't affect what you can or can't put into an identifier (the RID for resources, or the property name for properties)." --- Fully agree and thats what I meant when I mentioned above that the folder and file name can be any of his choice.

      The point that I want to pointout is that if you do put special char's into the name of your folder or file, then when you try to run a search via TREX, you will not be able to use those special char's in the search. Its not able putting special chars into the folder or file name...or in the foleer or file ID. Just a head-up for the requestor and that he is aware of the impact during portal search from TREX.

      If my above comments causes misleading and you do not agree, pls do correct my statement for the benefit of others in the forum... its a learning curve for everyone here, also for me 😊
