Re: 32-bit vs. 64-bit is not related to file size

You misread what I meant. I never said file size. I said large Excel spreadsheets. I take it you didn't view my link. Here it is again for your viewing pleasure:

As well as another one that is more specific to Excel 64-bit:


As for your Outlook files:

Hopefully you are using a newer version of Outlook and the updated PST format. The 2003 version, while supporting PST file sizes as large as 20GB, were known for corruption when they started getting close to 2GB in size and proved a pain to fix if they did corrupt. XP version and older were limited to 2GB tops. 2007 version was also limited to 20GB but I didn't see corruption issues with those PSTs and 2010 can accept PSTs as large at 50GB. But realistically, I would recommend multiple PSTs with smaller sizes than one large file. You risk less of a loss if one does corrupt on you and you won't take as much of a performance hit when trying to sift through your personal folder when kept at smaller file sizes.
