String is one of those data types which need finalization, and as such they cannot be stored in a File type. It is no point writing a record with a String field using a binary file type anyway, since you will be writing the address instead of the text string is a reference type. When you are declaring strings with a dedicated length, they are called ShortString value type. ShortString is not supported by the mobile compilers though.

I suggest you use other techniques to store text. See how to convert a record to text with json for example. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
