A workspace file would have an icon that looks a bit different from the
standard Excel icon - has more green in the body of the icon like a column
chart - and would have a .xlw extension. If that is it, just don't open it
You can go to the folder where it is stored (in the Finder) and delete it
- it only contains instructions to the app as to what files to open, how to
arrange the windows, etc. It isn't the workbook files themselves, so you
won't be deleting any of the files it "points to".
Based on the additional info, though, I'm not certain that is the problem.
It sounds like you have some damage control to do.
The first thing I would try is just running Disk Utility - Repair Disk
Permissions... It probably won't fix the problem but it can't hurt.
Secondly, start up from the OS X install disk, go to the Utilities menu &
launch Disk Utility from there - not the copy on your hard drive. Select the
HD from the left list, then run Repair Disk (button on the right). You may
have to run it several times until no errors are found. (Alternatively, if
you have Disk Warrior or Tech Tool Pro you might prefer to run that.)
If the problem persists, post back with complete details of any error
messages or dialogs you get along the way. We also need to know specific
versions of Excel/Office & OS X in order to go any further.
Another loooooong shot: Check to see if you may have accidentally had the
macro recorder running while opening those files before
(Tools>Macro>Macros).
