Thanks for the feedback, everyone. I agree that .Init and .Kill will cause problems when run from a FORM. I mentioned that in the article when doing an example of a button on the form. You only use this when using standalone code, which I was calling from the Menu, not a form which is already using the table in question. I wasn’t aware of the other SET option, which I will check out. The help file says that .UseFile should be used before the file is opened. > The **UseFile** method notifies ABC Library objects that the managed file whose opening was delayed by the LazyOpen property is about to be used. UseFile returns a value indicating whether the file is ready for use. A return value of Level:Benign indicates the file is ready; any other return value indicates a problem. **UseFile** should always be called _before_ a file is opened. I added a button to the Customer browse, and used an action to call the standalone procedure as a new thread. I didn’t get any errors or exceptions in debug mode. maybe because it was a separate thread? > [@How does MSSQL organize Record Data on disk in the database?](https://clarionhub.com/t/how-does-mssql-organize-record-data-on-disk-in-the-database/5766/4): > > Here is a free class/video on the concepts. If you are working with MSSQL, it is well worth your time, IMO. Brent Ozar is brilliant. He wrote a [series of tests](https://www.brentozar.com/sql/sql-server-performance-tuning/) you can run on MSSQL Server to make sure it is running well. Saved me a lot of trouble. --- _[View the full topic](https://clarionhub.com/t/introducing-clarion-filemanager/5760)._
