Hi all I recently duplicated my app - and as I want both apps to use the exact same data and to be kept in sync - I chose “Keep the same sheets” I want one of my apps to be open access with no sign in just to show a “dashboard” of data. There will be no user interaction with the second app (It will be shown on a big display in an office) I am using Glide Tables. But it got me thinking about how Glide Tables work (as in database tables on the data tab) I think I am right in saying that - in the data editor - - If I delete a table from one of the apps - it has gone for the other (and indeed all linked apps) - Same goes for records / data / row - change one, it changes in both ( I nearly deleted all my users in the second app! 😵) - If I un-link a table, it gets removed from the current app - but does not get totally deleted (I can re-link it to an app of I need) - If I delete an app - are all the tables deleted, or just unlinked? Bottom left, under data source, I can see all my, er, data sources - including ones that have not been liked. How do I see / delete the un-linked ones if I can’t access them through an app? Just curious more than anything - though that said, some likely have a lot of images so I could do with the storage space back Thanks, Andrew ---

> [@Andrew\_Davies](#): > > If I delete a table from one of the apps - it has gone for the other (and indeed all linked apps) I don’t think Glide allows you to delete a table if it’s used in other apps, but theoretically, Yes…same table means exactly that…multiple apps are connected to the same single table. > [@Andrew\_Davies](#): > > Same goes for records / data / row - change one, it changes in both ( I nearly deleted all my users in the second app! Yes, it’s the same shared table, so it’s the same shared data. > [@Andrew\_Davies](#): > > If I un-link a table, it gets removed from the current app - but does not get totally deleted (I can re-link it to an app of I need) This is correct. > [@Andrew\_Davies](#): > > If I delete an app - are all the tables deleted, or just unlinked? They are only unlinked. They are not deleted. > [@Andrew\_Davies](#): > > How do I see / delete the un-linked ones if I can’t access them through an app? I think you would have to first add (link) a table to a dummy app if you want to permanently delete it. If I’m deleting an app and the tables are no longer needed, I have gotten into the habit of deleting all of the linked tables in the app before deleting the app. ---

Thanks Jeff as always Guess I’ll need to make a new “dummy” app, link all the un-wanted tables, then delete them one by one Thanks again Andrew
