Honestly I don't get why so much software gets access to the entire filesystem just by running it. They should have made it so an .exe can only modify its own directory, a temp directory, and any file or directory passed to it by the user through the system's file picker or command line. That would solve 99% of the use cases. Every time I program something that deletes files I get worried about accidentally deleting the entire filesystem by mistyping something. I shouldn't have to worry about that. One of the reasons that webapps get as much trust as they do is simply because they don't have unrestricted file access. I wish there was an application format that promised the same on the desktop.
