You might seen the page URL in sharepoint 2013 looks like below. http://sp201323:8085/sites/TeamSite/_layouts/15/start.aspx #SitePages/Home.aspx In the above URL, you are looking for home.aspx to load.But the URL targets start.aspx .Do you know what is the reason behind this? This is nothing but Minimal Download Strategy Feature. Minimal Download Strategy (MDS) is a new technology in SharePoint 2013 that reduces the amount of data that the browser has to download when users navigate from one page to another in a SharePoint site. Benefits of using MDS Using MDS provides several benefits, including: Speed:   Smooth transitions: Browser navigation controls:   Other AJAX-based systems confuse the   previous   and   next   buttons in browsers.

Backward compatibility:   The MDS engine either provides MDS navigation immediately or detects when i

To convert a column of folder paths into a tree structure of rows, you can use a combination of Excel formulas and VBA code. Here are the steps to follow: Insert a new column to the right of the column with the folder paths. In the first cell of the new column, enter the formula =LEN(A1)-LEN(SUBSTITUTE(A1,"\","")) , where A1 is the first cell in the column with the folder paths. This formula calculates the number of backslashes in the folder path. Copy the formula down the entire column to calculate the number of backslashes in each folder path. Insert a new sheet in the workbook and name it "Tree". In the "Tree" sheet, create headers for the columns "Level 1", "Level 2", "Level 3", etc. up to the maximum number of levels in your folder paths. For example, if your folder paths have a maximum of 3 levels, create columns for "Level 1", "Level 2", and "Level 3". In the first cell of each co
