When selecting Session | Oracle User Lists and try to create an Oracle User List, the following error message is returned.
"Cannot create file <file_name>. The filename, directory names, or volume label syntax is incorrect"
When creating an Oracle Users List it creates a file in the User Files directory. The name of this file is made up of the name of the schema creating the list and the database it is in. The problem is that some of the characters that are in the database and/or schema name are not allowed in the name of a file, therefore you are getting an error saying the syntax is incorrect when it is trying to create the file.
Since the issue is with your database and/or schema name, the issue cannot be resolved unless your database and/or schema has a different name that contains only characters that are allowed in a file name.
