[Nina Sargsyan]" I've been looking for the save files and project files all over my computer for Resolve,"
It would be of fairly limited value to be able to access these files as they are a "no user serviceable parts" kind of proposition. They are part of a database.
If what you are trying to do is backup, archive, or move the projects, there is an "export" option that does just that and you can direct those to wherever you want.
There used to be an advantage to being able to drill down through the old Apple COLOR package, when there were no real extraction tools and exportability was not really an option, but why you would want to do this with Resolve would be an item of curiosity, at least for me...
