Six aspects of in-depth understanding of the library in Windows 7

What is the library in win 7? I think few people will go to understand this feature, the library is a bit like a large folder, but with the file There is a difference between the folder, and its function is relatively strong, so today we give you a comprehensive introduction to the library in win 7:

First, the similarities and differences with ordinary folders.

From the above interface, we can see that the library looks like a traditional folder. Indeed, from a certain perspective, libraries and folders do have many similarities. As with folders, you can also include a variety of sub-libraries and files in the library. But it's essentially different from folders. Files or subfolders saved in a folder are stored in the same place. The files stored in the library can come from all over the world. For example, it can be from an associated file on the user's computer or from a file on a removable disk. Although this difference is small, it is the most essential difference between traditional folders and libraries.

In fact, the management of the library is closer to the shortcut. The user can use the specific storage location of the file or folder. Manage them all by linking them to a library. In this case, all the files that the user needs to know can be seen in the library (as long as the user adds these files or folders to the library in advance). In other words, the objects in the library are a snapshot of various folders and files. The library does not actually store files, providing a faster management method. For example, the user has some working documents mainly in the D disk and the mobile hard disk on the computer. For the convenience of future work, the user can place the files in the D drive and the mobile hard disk into the library. When you need to use it, just open the library directly (provided that the mobile hard disk is connected to the user host), and you do not need to locate the mobile hard disk.

Second, after the deletion can not be re-joined is a loophole?

As shown above, the author first added a folder WinXP on the hard disk to the library. The way to add a folder to the library is very simple, just select the target folder, then click the button, click “include to the library” However, when I was testing, I found an organ problem. If you add this folder to the library, then delete the WinXP folder in the library. Then re-add this folder to the library. However, at this time the system prompts "Already WinXP is included in the library", and this folder will not be displayed in the library. However, the WinXP file in the library has actually been deleted.

Then, if the WinXP file exists in the library, and then add this file to the library, you can create it successfully. Only the name of the library will change to WinXP(2). It can be seen that this error is not caused by repeatedly adding a folder to the library. Because according to the test, the system allows the same folder to be added to the library multiple times. The reason for this error may be that there is a problem with the display in the library. The folders that have been added to the library cannot be displayed properly due to some special operations (such as deleting and then adding).

Third, delete the impact of the actual folder on the library file.

As shown above, the author has a WinXP folder on the hard disk, and then include this folder in the library. Now I will delete the WinXP folder on this hard disk. At this point, what is the impact on the WinXP folder in the library? First, the author double-click to open the WinXP folder in the library, you can still open. It can be seen that there are some differences between the management of library files and the management of shortcuts. If it is a shortcut, when the user deletes the original file, the shortcut will not open, and the user will confirm the accuracy of the path. In the library, you can still open the library files whose original folders have been deleted. There is nothing in the library that was originally saved. The most amazing thing is that although the original folder back is deleted, you can add files to the WinXP library in the library file, such as creating a new folder. Then, where is the newly added content library stored? At this time, the author opened the location of the original WinXP folder and found that a new WinXP file was created in the old place. This is automatically created by the operating system, which saves our newly created folder in the library.
