Otherwise, AutoCAD only writes the changed portion of the database to disk. Why "Always make sure ISAVEPERCENT is set to zero (0)." ? Update:Always make sure ISAVEPERCENT is set to zero (0).
Be sure to log in as a user with delete rights ever so often and clean out this directory. The autosave files will get written to this directory, but will not be deleted. Set up a directory on your server with WRITE rights, but without DELETE rights. One more TIP: If you want to RETAIN all autosave files regardless of whether you crash or not. DWGĪutoCAD 2006 users get a new GUI called the "Drawing Recovery Manager" - now you don't have to search for and manually rename files anymore. I have seen this after AutoCAD generates a fatal error and you get the dialog that says "AutoCAD can not continue, do you want to save changes?" - in this case, AutoCAD is giving you a chance to save your changes (although I recommend saying NO in this case - but I'll save that story for another day.) Anyway, in the above case, the autosave file(s) will be deleted.Īutosave files can be used by renaming them from. Sometimes AutoCAD may 'crash', but the autosave files are deleted anyway. sv$ = this is always the file extension for autosave files.Ī typical autosave file name might be: siteplan_2_4_2810.sv$ MDE Window number = a number generated sequentially regarding concurrent open drawings in each session.AutoCAD session number = a number generated sequentially regarding concurrent sessions of AutoCAD.drawing name = the original drawing name.The autosave file is named using this syntax:ĭrawing name_AutoCAD session number_MDE Window number_random number.sv$ The timer is also reset anytime QSAVE, SAVE, or SAVEAS is executed.The autosave file is created in the directory defined by the SAVEFILEPATH system variable.When this timer reaches the value of the SAVETIME system variable, the automatic save function fires, an autosave file is created, and the timer is reset.As soon as a new drawing is modified (in other words, when DBMOD does not equal 0), a timer starts.Here is more or less a rundown of what occurs:
AutoCAD's automatic save simply writes a copy of the current drawing to disk every so often, and when you shutdown AutoCAD normally, those file(s) are deleted. First and foremost, it is not a replacement for the QSAVE command. There seems to be a lot of confusion and misinformation out there regarding the operation of AutoCAD's automatic save function.
