SharePoint '/_layouts/' locations

Some times you want to jump right to a specific system list, page or go to the edit mode in a SharePoint site. I wanted to list all the famous urls I used for the past years and ask you to tell me about any other ones you know to add it here in the list. Other have already contributed a bunch 

(Remember for SharePoint 2013, 2016 you might want to add "15", "16" respectively after "/_layouts/" but if you don't SharePoint will take care of that for you) .. Also some of these are turned off on Office 365 SharePoint online.

WE CAN’T DO THAT FOR YOU BECAUSE THE FILE IS NO LONGER CHECKED OUT OR HAS BEEN DELETED IN SHAREPOINT DESIGNER

SCENARIO

In SharePoint Designer, When I tried to “Check In” a file inside, I got the below error:

WE CAN’T DO THAT FOR YOU BECAUSE THE FILE IS NO LONGER CHECKED OUT OR HAS BEEN DELETED

I already have tried to

• Close Share Point Designer and restart it again,
• Close SPD then clear cache from the following folder:
  • %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache
  • %USERPROFILE%\AppData\Roaming\Microsoft\Web Server Extensions\Cache

Unfortunately, the “We can’t do that for you because the file is no longer checked out or has been deleted” still persists.

---

CAUSE

This problem might occur in case, the file title contains disallowed characters like “/” as shown below:

---

SOLUTION

• Right-click on the affected file >  Select “Edit file in advanced mode“.

• Right-click again on the affected file > Select “properties“.

• The properties page should be shown.

• Remove URL > Change the title to an appropriate name by avoiding using the disallowed characters.

The file should be now checked in properly.
