Open File - Update Existing - What Does It Do?

[64Pacific 2]

Good day:

 

I have developed a couple of custom profiles and saved them while saving my model. As time goes on I have tweaked the profiles and have also exported them to a file on my desktop. I sometimes run into issues with my prints and it usually is a result of some setting going wrong which I have previously fixed. My question, if I have a profile set in Cura, say this profile is called "Printing A", the project file (.3mf) references the same profile.  I choose "Update Existing" on opening the file does this update only those settings in the application (loaded in memory) leaving my profile as it was previously or does it update the profile on disk? Essentially if I have a profile setup just how I like it and I open an older file referencing the same profile is that profile now tainted with the settings in the outdated file? What is the best practice here if I want to use an older files models and layouts with an updated profile which was fine tuned when printing other files?

 

If my thinking is right maybe a third option is needed when opening a file: "Create new", "Update existing (and profile on disk)", and lastly "use settings from saved profile"

Update existing will load the settings in memory. This marks the profile as dirty and will trigger a save to disk in a few seconds (or when closing Cura).

 

If you don't want this you need to use "create new".

Thank you, I will have to watch for that now that I know what it does - not that my profiles are overly customized, rather I am trying to limit failure points (currently all of my prints are failing after the first two)...
