Each user account has their own folder named ‘Libraries’, with four sub-folders named ‘Documents’, ‘Music’, ‘Pictures’ and ‘Videos’.These four folders are not to be confused with the user folders named My Document, My Music, Etc.
Libraries do not contain files but a pointer to files that can be physically located in a folder anywhere on your current partition or drive or other partitions or drives.
You can experiment with using libraries by creating a new user account; give the account a simple but obvious name, for example ‘TestUser’.
Now log on to your test account and press the Print Screen key. Open Windows Paint and past the print screen photo into Paint. Save the photo (give it a name like Test_01.png) to the folder named ‘Pictures’.
Now do another print screen and this time use Paint to save the photo to: C:\Users\TestUser\My Pictures. Name this file Test_02.png.
Where are both photos stored? Now open Windows Explorer, you should see the folder named ‘Libraries’ and one of the sub-folders named ‘Pictures’. Click on the ‘Pictures’ folder in Explorer’s left pane, you will see both .png files in the library.
But you say I saved only one photo to the libraries ‘Pictures’ folder and the other to the TestUser\My Pictures folder. The answer is that the library folder only contains a link or pointer to the actual location of both files. Physically both these files are actually in your ‘My Pictures’ folder.
