Office Freeze when file open

[BillyP]

The my docs is the default folder when I use office to
save and open files. When I go to open a file the pc
hangs in the my docs folder. There are over 300 folders
in the my docs folder. When I change the default folder
to the desktop it works with no poblems. I can even then
go to the my docs folder with no problems. This is ok for
all the office apps but outlook. I can not change the
default location. So I can not attach a file to a email
cause pc keeps freezeing. Any help would help a lot.

TIA
