The Data Files folder is not appropriate place to locate your own files.
Katalon Studio owns the Data Files folder as a temporary storage for “Data-Driven Testing” feature. KS does not expect users to locate their own files in the Data Files folder. Katalon Studio might do something myterious to the files in the directory, though I’m not sure, as Katalon’s document explains nothing about the Data Files folder.
You can create a folder in the project directory with any name, for example "mydata". It would be safe for you to locate your own files into this dedicated place.
Though I am not saying that introducing mydata folder will change something. All I’m am saying is no smell, the better.
