I have a Windows 8.1 Pro system with C:\ only containing the OS and some software. I also have a drive F:\ where I keep all of my files. Today I did a reset of Windows to get back to a clean slate.
One of the folders on F:\ is my Dropbox folder, so I've been going through help articles to make sure to simply point Dropbox to F:\Dropbox and letting it index those files in place, instead of redownloading ~300 GB.
One user described a problem where, because the Owner of the files was left over from his previous Windows installation, Dropbox began making conflicted duplicates of everything. This led me to go check out who the Owner is on some of my files.
Permissions, Ownership, UAC and ACLs have never been my strongsuit. Frankly, I don't know if my account was the Owner of all my files in the old system, and, if not, why not. I don't understand much about what determines who owns a file when it is created, downloaded, copied, whatever. Now that I'm looking at the Owner of a few of these files, I'm noticing a trend that most of the ones I've looked at are owned by an entity with a long string name that means nothing to me. S-1-5-21-blahblahblah. The blahs stand in place of a long set of numbers.
My best guess is that this string somehow was used in place of any file my user was the Owner of in my previous installation. Should I be taking ownership of all of these? Is there any harm in simply taking ownership of the entire Dropbox folder and its contents before I set up syncing?
