I try to make the same with the same file in old version ofcDB:
Print DBEngine(0)(0).TableDefs("Fatture_Scadute").Connect
Text;DSN=Fatture_Scadute - specifica di collegamento;FMT=Delimited;HDR=NO;IMEX=2;CharacterSet=850;ACCDB=YES;DATABASE=C:\Nuovo QC_DT\Input
With
tdf.Connect = "Text;DSN=Fatture_Scadute - specifica di collegamento;FMT=Delimited;HDR=NO;IMEX=2;CharacterSet=850;ACCDB=YES;DATABASE=" & percorso & "\input"
it works!!!
So the problem was the filename in path, that work for .xlsx, I suppose, for the name of sheet....nice!
Thanks you all for help
