> I've come across a specific edge case, where if you have a file A in one directory then that same file name in another (with one of them being newer). So the program then tries to sync the newer file to the older file by opening it. However, if the older file has restricted permissions (errors out on open), should the program exit and report why. > Or should it delete the old file and then create it again with the required perms (default or carried over)?

> Additionally, if the newer file is smaller than the old file, the old file may be left with artifacts of the old copy (which is a result of our code). Is there a way to wipe the file's contents before writing to it? or should it just be simply deleted if one exists before syncing to it?
