I use dropbox business for my work and found that when I try to access my dropbox folder or files syned in my pc hdd, it gets significantly slow within certain period of time.
I synced dropbox file as offline so all my files saved in local hdd and when I access dropbox files through pc app, it is very slow to move and access among files and folders.
I tried to reset the dropbox app and even my pc hundred times but it lasts only few days and gets back to slowness.
