Can Photoshop open large TIFF files?

Question

Hi,
Windows 32-bit OS cannot open TIFF files bigger than 4GB. I need to work on TIFF files that have a size up to 10GB. Does Photoshop support this?
Thanks,

The scanned files come from a big Roche cells scanner. Computers which have the Roche utility software can open it and those computer are in 32-bit or 64bit. I have even downloaded a TIFF image, from the nasa site, of 25GB and i could open it on my 32bit Windows OS.
After doing some research, I found the following site http://www.remotesensing.org/libtiff/document.html . From there, I went to the following site : http://www.awaresystems.be/imaging/tiff/tifftags/extension.html and it seems that some tags within the tiff files are not recognized by some viewers.
I also installed Microsoft KB2635500 http://support.microsoft.com/kb/2635500, which solves issues when we try to display a large TIFF file that contains multiple pages, althought this is not the case as we speak of a single file. I also should have tried before installing this KB.
The tiff file (9GB) the user obtained when scanning with a Roche cell scanner is a TIFF file extension. The file I downloaded from the NASA website is also a TIFF file (25GB). I have a 32-bit OS and I could open the NASA tiff file without any problem but another user with a 32-bit OS cannot open any tiff file bigger than 4GB. That user gets the error message stating the file is corrupted or not supported.
I will check later on in the morning when this user arrives.
