Auto-Save
Screen Writer Studio keeps two backups of every script you write. The first is a backup of the work you are presently doing. Every time you do not press any key or click the mouse for 20 seconds, it will save a copy of your work as it is right then. If you are typing constantly with no 20 second breaks, then after 10 minutes it will save a copy as you are working. So this backup copy is never more than 10 minutes old.
This auto-save copy has the same name as your saved file but has an extension of sav instead of sws. So for the file tutorial.sws, the backup file is tutorial.sws0. For a new document that has not been saved, and therefore has no file name, this file will use the name given it until it is named, which is usually Script1.sws0.
If your computer loses power or locks up, when you restart Screen Writer Studio, it will open the .sws0 file. When you first save the file, Screen Writer Studio will ask if you want to change the extension back to sws. You should do this.
The .sws0 files are deleted when you save or close a file because they are now identical to the saved file.
You can turn this feature off or change the delay times.
Auto-Backup
Every time you open a file to edit it, Screen Writer Studio will save a copy of the file before your editing, with an extension of sws1. In the case of tutorial.sws, the backup would be tutorial.sws1. This file is copy of the file when you first open it, before any edits or saves. Saving a file multiple times while editing does not change the .sws1 file. It is a copy of the file before your editing session.
Unlike the .sws0 files, the .sws1 files are never deleted because they are different than the saved file. (If you open a file and do not change it, the .sws1 file will not be created. It is when you first save a changed file that the .sws1 file is created.) Every time you start a new editing session, the old .sws1 file is replaced with the new .sws1 file.
If all the changes you made this editing session are terrible and you want to go back to the previous version, open the .sws1 file. When you first save the file, Screen Writer Studio will ask if you want to change the extension to sws. You should do this.
