can anyone help
First things first. Autosave files have the extension SV$. Files with
the extension AC$ are temporary files used by AutoCAD and may or may not
contain valid drawing data.
If you have a drawing open and you do not save within the time you set
for autosave to kick in, then an SV$ file is created in the folder
nominated in the options dialog. If you subsequently save the drawing
before the next autosave, then the SV$ file is deleted as it is no
longer needed - you have performed a save. If you skip 2 autosaves and
you have AutoCAD set to create BAK files, then the first SV$ file is
renamed to a BAK file before the autosave is done. A subsequent save
will see the SV$ file deleted, but the BAK file of the autosave will
remain there.
If you close the drawings correctly (saving or discarding changes as you
decide), then the autosave files relating to those drawings will be
deleted.
So if you do not see autosave files (SV$), then this means that saves
have been performed or the drawings closed off and the changes saved or
discarded as you decide. The only time you will see SV$ files remaining
is if AutoCAD crashes and an autosave file exists.
The setting to change the autosave interval is in the Options dialog.
You can also access it directly from the command prompt with the
SAVETIME command.

I do not find dean's info useful or related to real working practice. in the last 4 offices I've worked in it is normal to work on a number of drawings simultaneously and not have to save everything I have every time I do anything else. The day is too short. Bak should be reliable and autocad should be stable.
The Autosave clock starts ticking as soon as AutoCAD considers the
drawing has been modified (i.e. DBMOD is no longer 0). There is no
point in doing an autosave if nothing in the drawing has changed.
It may be a typo, but the autosave has the extension SV$ and not AC$.
One of the big problems with AutoCAD is that it cries wolf too often.
For example, the variables TSPACEFAC and TSPACETYPE are NEVER saved
anywhere, yet changing them will see the value of DBMOD change to
indicate that drawing has changed. Similarly, if you do not save
settings in the plot dialog, AutoCAD will still flag the drawing as
having been altered merely going into and back out of the plot dialog.
Similarly, using the "Copy with basepoint" will see the drawing end up
as being considered modified when NOTHING has changed. With all these
false alarms, users can never really be sure if they have actually made
a change to the drawing or not.
The other point that was raised was the setting of ISAVEPERCENT. This
should be set to 0. This will force a full save every time, and the
additional time required for this is very small but the benefits are
fewer problems.
Earlier versions of AutoCAD did not delete the autosave files on proper
exit or after a save, and users complained about having to delete these
manually, so now we have them automatically deleted when considered
unnecessary. Maybe it should have been an option like it is to create
BAK files.
