Answer 2

Hello. First sorry by my english (spanish only).
Using files, can not support multiple access, not support transaccions, and more.
May be you can use threads with syncronize a file for multiple access, I do not know, i do not test it.
Think if a user try register to file by remote access, and same time other user register same data before finish the first, big problem, so you have that close access, register first user, update de filedata, and manage other user... I dont know
