Directory size/max files in index.

Hi,
One of my colleagues claims there is an issue with WindowsIndexing in that there is a maximum directory/project size (ofaround 2000 files, he claims). Above this figure, files added arenot indexed and hence are not returned in PDM searches. He alsoclaims that as time passes and files are added or removed, theyunpredictably fall out of the index or are suddenly included.
Before I write a program to create a large batch of files, forbulk check-in, to test this claim, please, does anyone know if he'sright? His evidence seems a little anecdotal and the claim is quitedifficult to substantiate.

Thanks for your help.SolidworksWorkgroup Pdm
