I do a little research last night by the links you post above, and I can have drag and drop for autocad only by its main windows class by ahk_class, at least for the first files.. then I can drop with ahk_exe, weird. Anyway, it's not practicle have a global drag&drop for Autocad, because it's very hard to know how long a file cad need to load,it will vary from 0.x second to half a minute, and before the last filed was completely loaded, it won't accept new drop in.hi5 wrote: ↑2019-10-19, 07:38 UTC Some thoughts:
* Perhaps AutoCAD is running as administrator (and in that case F4mm should also run as admin I think)
* Perhaps AutoCAD isn't running yet and/or the files are dropped to quickly, you can try and play with the D&D and Open delays (in milliseconds)
Possibly: Quick search shows you're not the only one it seems with that request2.1 Drag & Drop delay gives program to start up before trying to drop the files - you may need to apply trail and error.
2.2 Open delay, pauses X ms to open next file.Some people use a launcher (I don't know anything about your version of course)

https://github.com/vanowm/AutoCAD2000-2002_Launcher (perhaps use this as "editor" in F4mm)
One more things, I noticed the non-ASCII name file fail to drop, is there something of the filename string converted to before it drop to the application?
