how come one paricular excel file will not open w/o errors?
 

I have a PocketPC that I sync up with my Home Computer on a daily basis. I
have a few files of excel and of word. This morning while trying to access
one particular file of Excel, I wasn't able to do it and the weird thing is,
all of my other files are still retrievable. Is this file corrupt? Is this
file somehow marked as "read-only"? --even though I checked the properties
and it said it wasn't.
