Resize columns in grid to fit data
You can have the grid automatically adjust it's columns to have data displayed in optimal way.
Optimal column width - calculates optimal width for each column, to fit the header and all data rows
Stretch columns to fit screen - makes column proportionally wider or shrinks them to fit grid width. It doesn't analyze actual data, so it's much faster compared to 'Optimal column width' option, but result can and may not satisfy.
Only for tables up to # records - limits this feature for smaller tables only. You can enter your threshold value.
Always fetch and display tables' record count
You can have record count displayed right by the each table's name. This slows down database refresh, so for huge databases you may want to leave this option off.
Display SQL commands sent to target database
Enterprise version only. You can have all the SQL commands sent to the target database during conversion logged and displayed in conversion summary dialog. It can be saved to file from summary dialog.
Also save to file - automatically save to file of your choice.
Show legacy database connections
Enable slower, but more compatible database approaches. Fox example, our direct file DBF reader does not support indexes yet. By turning this option on, you can convert your FoxPro databases using OLEDB connection, which supports indexes.
