C#

string root = Server.MapPath("~");
                string path = "\\Brands\\" + Session["brandname"].ToString() + "\\" + Session["departmentname"].ToString() + "\\" + Seasonfolders.SelectedItem.Text + "\\" + Session["groupname"].ToString() + "\\" + item;
                string originalpath = System.IO.Path.Combine(root, path);
                bool isExists = System.IO.Directory.Exists(Server.MapPath(@"~\\" + originalpath));
                if (!isExists)
                {
                    chkstyles.Items.RemoveAt(i);
                    File.Delete(@originalpath); 
                }

Expected Output:
root=E:\sg
path=\Brands\a\b\c
originalpath=E\sg\a\b\c\d

but produced C\a\b\c .... Didn't get the current accessing folder path. But with this, I worked in all codes which worked fine but hectic at one module alone. Doesn't know how it worked there and not working here.

Well no...it's not going to work.
Look at what you are doing:

C#

string root = Server.MapPath("~");

Which gives you "E:\sg"

C#

string originalpath = System.IO.Path.Combine(root, path);

Which gives you "E:\sg\a\b\c\d"
Then, you do this:

C#

bool isExists = System.IO.Directory.Exists(Server.MapPath(@"~\\" + originalpath));

Which is checking to see if a file exists called "E:\sgE:sg\a\b\d\c"

Which is going to fail...

Why are you trying to include the root folder twice?
