How to open multiple Excel workbooks

[JARHTMD]

Sometimes (usually) I can't open multiple Excel workbooks at the same time. Sometimes (not often) I can. I try double-clicking on the file(s); right-click/open; etc. Nothing seems to work consistently.

When I have BookA open, I have to close it before can open BookB.

I "think" this started with Win10, but I'm not sure. I'm using Excel2007.

the only limitation that I am aware of is available memory. If your files are not exceedingly large in byte size, then you should be able to open several at a time. You also have to consider any other applications and their data files that you might have running at the same time.
