Opening multiple drawings in MEP 2008 sp1

[bearden383]

When opening multiple drawings from explorer only about 80% of the drawings actually open. Is there a setting in ACAD that I need to change or is there a workaround? I've tried this which I got from other posts

"From File Explorer > Tools > Folder Options > File Types > wait, wait some more > highlight DWG in list, > Advanced
> highlight open > Edit... > (If open isn't there use New.. to create it.)

Application used to perform action:

"C:\Program Files\AutoCAD 2008\acad.exe" "%1"

Use DDE
checked

DDE Message:
[open("%1")]

Application:
AutoCAD.r17.DDE"

But it didn't change anything.
We just upgraded from 2007 which hasn't been uninstalled.
Any help would be appreciated.

Hi, Welcome to AUGI.

Does "80% of the drawings" mean more than one at a time?
If so, the DDE method is not the problem.

by 80% I mean that if try to open 5 drawings only 4 will open. If I try to open 10 Only 8 will open.

I thought so.
Hmm. I don't know of any acad variable would have that effect.
I'd guess at (lack of) memory but that wouldn't give a consistent result.

I've had the same problem in Vanilla AutoCAD. I've just gotten into the habit of opening AutoCAD first and either dragging the files into the program or using the Open menu. It works fine both ways.

double check your changes

"C:\Program Files\Common Files\Autodesk Shared\AcShellEx\AcLauncher.exe" /O "%1"

[open("%1")]

AutoCAD.r17.DDE
