I am using Excel 2010 and want to manage a large Excel files.
So I would like to open a new Excel Instance when opening every file from my Windows Explorer. At the point all files are opened in the same Excel Instance.
Any assistance is kindly appreciated.
John.

Go to a folder in Windows Explorer, then Tools -> Folder Options, then the File Types tab. For each of XLSM, XLSB, XLSX, etcetera, select it, then click Advanced, select Open in the Actions list, then click Edit.
Adjust the settings to:
Application used to perform action: - "C:...\EXCEL.EXE" "%1"
Use DDE - Checked
DDE Message *LEAVE BLANK*
Application - Excel
Topic - System
You need to launch excel and then load the file, so it will be in another instance.
