I know that this idea has been floated twice before and I also note that the Access team have responded and indicated that this is not part of the development and I also note that its been closed so more votes cannot be taken on it. Thought it was important to re-open because its actually quite a popular idea. I understand that SQL Server / SQL Azure or SQL Express are the way to go if users are wanting larger backends but for quick and dirty working for ETL projects or random data analysis of large datasets individuals may not wish to have the additional overhead of enterprise grade backend database install. Remember a basic SQL Server install will require SSMS and the SQL engine ontop of Access - For individuals in large organisations this may require petitioning central IT for a number of weeks or months. I would always recommend using SQL as the backend for even smaller projects but increasing the max file size would just make Access even more flexible. Anyway keep up the good work MS
