You cannot modify a table linked in the FE. &nbsp;You must do so directly in the BE. <br />
<br />
Close the FE entirely (make sure EVERYONE is out of the database), then copy that BE file over to your machine. Make your changes there, then copy the updated BE back to the original location.

I had a on file database ad then made the split. Now I need to modify some tables and ms/access 2013 does not allow to modify them either via the front end or, directly, in the back end (on the back end refuses to open the file due to &quot;a security concern&quot; and requires me to digitally sign the file, which I do not know how to do.<br />
I went to the trust center and added the back end location as a trusted locations, but it did not help.<br />
<br />
what shall I do? can anyone help?

Microsoft Access is a rapid application development (RAD) relational database tool. Access can be used for both desktop and web-based applications, and uses VBA (Visual Basic for Applications) as its coding language.
