The SQL Anywhere server does not support this feature. You can store data on disk as individual files (and store the key to the file, e.g. its filename in the table row) quite easily using Directory Access proxy table (or use xp_read_file/xp_write_file) but there would be no transactional consistency guarentees using this method.
Ultralite does support storing of blob data in a separate file - see CREATE TABLE's AUTOFILENAME - but I do not believe that UL guarantees transactional consistency?
