Drive letters in paths of table names can only be used with Advantage Local Server. When using Advantage Database Server for NT, fully qualified paths must use UNC (e.g., "\\server\volume\path\table"), because the SQL statement is parsed at the server where client-side drive letters are not meaningful. Note that tables referenced like this must be enclosed in double quotes or  (brackets) because they contain non-standard characters (see Use of Non-Standard Characters in Names).
If relative paths are used in SQL statements, the path is considered to be relative to the connection path. For example, a table referenced as "..\alternate\info" would refer to a directory named "alternate" that would be expected to be parallel to the original connection path directory.
