Hi Holly,
You might check with Ctr+End to check your lastcell position.

If that looks okay, meaning it is near you data then perhaps
you have added User Defined Functions that have volatile
added so that they are calculated everytime a calculation is asked for.

My file was crashed last Friday, after recovery, the file has repaired next
to file name when I open it. Also it starts calculating file every time I
open it. I copied the tabs I need to use to a new file. It's still doing
calculating every time when I open it.

These tabs I copied to the new file, only have add functions in few rows,
it's a small file, but it takes long time to calculating this small file
everytime when I open it.
