Naming Conventions in AEM for XDP files
We are in the process of uploading XDP forms created in Designer into AEM as HTML files. I'm having a hard time finding documentation stating why we should not have spaces in the XDP file names before we upload them. I know it is the proper way to name files but I need documentation (proof and reasoning) to present in order to suggest a procedure change. Can anyone direct me to this as I know it exists just cant find it for this exact use case.
Thanks!
