Helpful if you save a crop and do not want to overwrite the full photo, and you are saving back into the source folder location.
Hello @drdancm 
When in Photo AI, the app will save by default a copy. The file if you do not have any suffix/prefix/and keep the Topaz enhancement naming toggled off, will show a warning message. This means it will NOT overwrite, and will be renamed with -2.
If you DO toggle the “Allow Overwrite” to on, then another warning message will appear.
The option Save AS is not needed, as it is already implemented by default.
Let me know if you have any more questions
