MS info says the Roaming folder contains data that can move*. I have only 1 pc, connected to no other device to sysc with nor do I use PC-PC. Am I making myself more vulnerable to hackers? If so, I'll find a way to disable whatever in that folder.
* Roaming. This folder (%appdata%) contains data that can move with your user profile from PC to PC—like when you’re on a domain—because this data has the ability to sync with a server. For example, if you sign in to a different PC on a domain, your web browser favorites or bookmarks will be available.
Local. This folder (%localappdata%) contains data that can't move with your user profile. This data is typically specific to a PC or too large to sync with a server. For example, web browsers usually store their temporary files here.
LocalLow. This folder (%appdata%/…/locallow) contains data that can't move, but also has a lower level of access. For example, if you're running a web browser in a protected or safe mode, the app will only be able access data from the LocalLow folder.
The apps themselves choose whether to save to the Local, LocalLow, or Roaming folders. Most desktop apps use the Roaming folder by default, while most Windows Store apps use the Local folder by default.
