Quicken cannot open the data file because it is in use by some other application

Quicken 2013 (Windows 10) worked fine right after a reboot. If I closed Quicken then tried to reopen, I would get the error "Quicken cannot open the data file because it is in use by some other application"

For me I solved this by changing the extension of the C:\ProgramData\Intuit\Quicken\Config\FILIST.QFI file. Then relaunching Quicken worked.

Where (full path) is your QW.EXE file located?

Where (full path and file name) is your Q data file located?

Do you use OneDrive, Carbonite, etc (ANY third party product) to backup your Q data file?
