How to delete Dropbox from my computer without losing the files that ended up there?

Hi there Jinge, sorry to hear about this.

It sounds like you may have enabled the computer backup feature upon installing the desktop app on your computer.

In that case, you can disable it as outlined here.

I hope this helps!

Thanks for suggestion/instruction but I can't work it out at all.  When I "search" for Dropbox I get -Blocked-.rfx which means nothing to me.  Also visible is C:\Users\wejoy\Dropbox\PC\Documents\IT and Bak\Brian backup files\Backup sept18\Documents\My RoboForm Data\Default Profile which probably is of no help except that it show the relative location of Dropbox. 

Hi Jinge, in order to disable Backup, you need to make sure your app is running, and access its preferences.

In order for you to do so, you'd need to check for the Dropbox icon next to your WiFi, click there then click your avatar (profile picture or initials) in the top-right corner.

Click the Backups tab, and the option should be there under Manage backup. If not, let me know. 

I'm a right duffer here, aren't I?  Where or what is that WiFi location? 

Don't worry about it, that is why I am here Jinge. 

It would be on your task bar, next to the date and time. 

Found what I think you mean bi WiFi (Internet access) but no sign of any Dropbox icon etc.

Hi Jinge, do you see anything when accessing your Backup page online? You should be able to see your Backup there, and disable it. 

If not, then could you try to do a quick re-installing on the app using this link? 

Right, I've now installed Dropbox, as far as I can tell, by having clicked on your instruction.  And, now I see a Dropbox icon on the task bar.  What comes next?    (By the way, if it is pertinent, I do not have a mobile telephone.)

I can now see, in my C: list of stuff, that Dropbox is listed and, apparently, has nothing in it.  Previously that wasn't the case so has this new installation actually replaced the earlier?  Also, I haven't noticed any reference to backing up or cancalling it.
