Hi, Thanks for reply;
Sometimes the disk is having the mounted volume inside.
Suppose you have I drive having 50Gb free space out of 100GB and might it contain some folder for eg dumps which is a mounted volume and if you right click dumps and check teh properties, it will say that the folder is mounted and by clicking on the properties tab it will show thw free space available on mounted folder dumps which will be totally diff from I drive space...
But I need to check same by some query or script;;
Hope you got mine point
