This can be a decent administrator device to screen all reports create on SSRS case and it can be helpful particularly if the rundown of your reports is getting huge.  It's a basic question on "Reportserver" database which can be once in a while named differently much the same as mine is: "Reportserver$mike" (named occasions), yet for SSRS introduced on default case it ought to be this one from beneath:

USE [ReportServer]
GO
SELECT
  Name,
  [Path]
  --,[Description]
FROM [dbo].[Catalog]
WHERE [Type] = 2
ORDER BY [Path]

Result:
Name Path
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
AdventureWorks_Base /AdventureWorks/AdventureWorks_Base
Customers_Near_Stores /AdventureWorks/Customers_Near_Stores
Employee_Sales_Summary /AdventureWorks/Employee_Sales_Summary
Sales_by_Region /AdventureWorks/Sales_by_Region
Sales_Order_Detail /AdventureWorks/Sales_Order_Detail
Store_Contacts /AdventureWorks/Store_Contacts
(6 row(s) affected)

Likewise, here is a little extensio for the query which I want to utilize this one with guardian envelope structure included:
USE [ReportServer]
GO
SELECT
  Name,
  FullPath = [Path]
  ,ReportParentPath = REVERSE(SUBSTRING(REVERSE(Path), CHARINDEX('/', REVERSE(Path)), LEN(REVERSE(Path))))
  --,[Description]
FROM [dbo].[Catalog]
WHERE [Type] = 2
ORDER BY [Path]

For more extensive checking contemplations I prescribe probably the most vital tables in Reportserver database: USE [ReportServer]
GOSELECT * FROM [Catalog]
SELECT * from [dbo].[DataSets]
SELECT * FROM [dbo].[DataSource]
SELECT * FROM [dbo].[Users]
