The UDF (user-defined-function) directory folder is used to perform tasks that Firebird/InterBase can't. It is an external database function written entirely in another language, such as C++ or Pascal, to perform data manipulation tasks not directly supported by Firebird/InterBase.
The databases.conf file database holds the security.db where it can locate the security3/4.fdb. Inside the function, you can directly change the RemoteAccess or DEfaultDbCachePages. It can also include some configuration information for individual databases.
mcvcp100.dll and msvcr100.dll are extremely important because the firebird windows version is always compiled with the Microsoft Visual Studio compiler. the Microsoft Visual Studio compiler uses these runtime libraries to connect the fbclient.dll. If these files are missing, or you do not have the correct version, you might get an error message that you cannot find the fbclient.dll. Make sure that mcvcp100.dll, msvcr100.dll, and fbclient.dll are in the same directory where the firebird application is, so you will not have any problems.

security3.fdb or security4.fdb are important files because the entire database security depends on identifying a user and verifying the authority (authentication). Each record in these security3/4.fdb is a user account for one user. For each database, the security database can be overridden in the databases.conf file and any database can be a security database, even for the database itself.
