Excel 2013 files are opening too slowly — what is “Linking: Mobil.XLS”


When I open files (simple files without excessive formatting) they are very slow to open. When the new file is being opened, Excel says "Linking: Mobil.XLS" or "linking: EREC summary" amongst a few others. It may take up to 3 to 4 mins for the file to open.

I fail to understand how in any way that these files are linked to my file. Is there a way to get rid of the links? Office 2010 is way faster in opening the same file.


  • These are files copied from a network server to a local PC and then opened.
  • They are not password protected.
  • They do not have excessive formatting or formulas (simple text).
  • I'm using Windows 7, with recently upgraded Office 2013
  • The hardware acceleration is removed – so no more lag coming from animation stuff.

I couldn't observe similar issues before the upgrade from 2010 to 2013.

I have found the solution to my problem.
Under the Formulas tab locate the Name manager and open Name manager dialog
In the Name Manager dialog under the "Refers to" column locate the "Names" which have access to servers (starting with \\ABC\ etc).
Delete which ever "Names" are not relevant to your file.
