how to resolve the error message “the file .qbx has unknown content”?

Hi,

could you please explain how you get that error? Describe or show picture if …

Brg,

Queries created in Toad’s ‘Query Buikder’ are saved as *.qbx files. I use the tool frequently and when re-opening these files i get the error “Cannot open the selected Model. The file “anyname.qbx” has unknown content.” about 70% of the time. This has been true for 11.6 as well as 12.1. If i save the ‘select’ statement in notepad - open a new Query Builder window - paste in the statement, the tool will re-create the state of the QB tools - just buggy, frustrating and I have lost valuable work - a fix would be appreciated. Thanks! Craig
