Database File Naming Conventions
In earlier versions, InterBase database files were given a file extension of
gdb by convention. InterBase no longer recommends using
gdb as the extension for database files, since on some versions of Windows, any file that has this extension is automatically backed up by the System Restore facility whenever it is touched. On those two platforms, using the
gdb extension for database names can result in a significant detriment to performance. Linux and Solaris are not affected. InterBase now recommends using
ib as the extension for database names. Generally, InterBase fully supports each file naming conventions of a platform, including the use of node and path names.
