I have been using autosave for years.
The text below is the installation instructions from my download of autosave.zip.
The autosaved flights are in your saved flights - listed under autosave.
Hope it will be of some help.
AutoSave: Automatic flight saving for FS98, FS2000, FS2002 & FS2004
Version 1.50, 24th November 2003
Place AutoSave.dll in your FS98/FS2000/FS2002/FS2004 Modules folder.
It will save flights ("STN" files in FS98, "FLT" plus "WX" files
for the others) at regular intervals, so you can retry that crashed
landing or quickly recover from other problems.
By default AutoSave saves a flight every 60 seconds, and keeps the
last 10 files. These files are placed in the Pilots folder for FS98
and FS2000, in the Flight\Myflts folder for FS2002, and in the
standard user data folder selected by FS for FS2004. They are named
AutoSave day hhmmss
where 'day' is day of the wek. The time is the computer's local system
time, NOT the one on the FS clock. This format allows you to easily
select a suitable file to restart from. With 10 files at one minute
intervals you have the last 10 minutes covered.
Note that AutoSave does not normally save these files whilst the aircraft
is on the ground (EXCEPT maybe in slew mode if you started this mode
in the air). This allows you to take a breather and recoup after a
crash! <G>. If you really want it to save files when on the ground,
you'll need an extra parameter -- see below.
The files aren't saved whilst FS is paused, either, to avoid overwriting
all those useful ones which identical copies of a paused simulator!
AutoSave creates a file in the main FS folder called AutoSave.cfg. This
contains two sections -- [User] and [Files]. don't edit the latter, as it
is used by AutoSave to keep track of the files it creates. However,
you can change the two parameters in the [User] section to suit yourself:
gives the interval between saves in Seconds.
gives the number of files to be retained (1-30).
You can also add parameters for an optional additional file which has a fixed
name and which is saved regardless of FS's mode or state:
AlsoSave=name of file
For example, adding
will save the flight as "My Restart" every 30 seconds. This is in addition
to the timed files above. The idea here is that you can set "My Restart" or
whatever as your default flight, so after an program or hardware crash, or
power outage, you can simply load up FS and continue from a few seconds
before the problem.
If you want only this behaviour, and no timed files, set the File parameter to
zero (thus "Files=0"). Then only the "also file" will operate.
Finally, if you want AutoSave to save flights at intervals whilst you are
on the ground, as for instance when taxying, add this parameter:
It still won't save flights whilst paused, nor if the latitude and longitude
of the aircraft has remained exactly the same as the last time.
Changes to these parameters are not effective until FS is reloaded. (If you
decrease the number of files retained, you should also delete the excess files
in the Pilots (or for FS2002, the Flights\Myflts folder) folder, as they will
then be left untouched by AutoSave).
