Windows 2000 & XL 2000

I am trying to open a file from a folder which is in a folder that has
approx 1400 other folders in it.

When I try and do this from within XL the File Open the 1400 folders
above it and the files below the last folder do not appear in the
window. The dialog box freezes and all I can do is press the "X" at
the top left, which gives me an error message and kicks me out of XL.

The file opens fine from within Explorer.

Apart from the obvious "Open it from within Explorer", does anyone
know why this might happen? I suspect a limitation on the number of
folders . . .


TIA

Steve
