Which AutoSave are you wanting to delete ?
AutoSave doesn't create new files except empty skeleton when we quit without saving a newly created document.
Tonza wrote about them. They are the results of a bug.
Documents are supposed to be saved automatically when we create new ones from templates or thru Duplicate.
At this time we may find these "skeletons" in the folder :
Macintosh HD:Users:<yourAccount>:Library:Autosave Information:
This morning, mine contain only three of them because I worked most of the time from an other bootable HD:
Document Numbers non enregistré.numbers
Document Pages 2 non enregistré.pages
Document Pages non enregistré.pages
After checking that they are empy, I trash them.
If you were asking about Versions, it's an other problem.
We may remove some versions thru the official GUI:
There is also the brute force scheme : rename a file or move it on an other device.
The versions will be dropped.
From my point of view it's annoying. Would be better to adjust the links automatically when we rename a file and display a dialog warning when we move a file on an other device.
I'm sure that some users already loose their old versions this way.
