i have already searched the web but can't find any awnser.in acad 2013 i have set my default save file format on acad 2007, this works.but when i close a drawing and hit yes on the question "would you save the drawing" then i saves the drawing in acad 2013 fileformat. where can i change this setting?thnx in forward.Erik Duinkerken

In OPTIONS.

i have set my file save (save as) in the dialog box options set as autocad 2007/lt2007. when i hit ctrl-s or type save / saveall of select the quicksave button it all works fine.but when i close the drawing or exit autocad then i get the question to save te drawing while closing. when i hit yes. then autocad saves the drawing in Autocad 2013 file format and not 2007 as set in the options dialog.

If you have set it in Options and clicked on the Apply button then it should work.  And you know it is saving it in 2013 file format how?  Where are you getting this information?

Please click the Options and the click the Apply button.

Is there an echo in here?

@John, sorry for my late awnser. i had a vacation :), i discoverd the problem with a collega who's working with an older version of acad.
