The directory to be displayed in S1 may refer to the desktop or other storage paths of a computer which are designated by a user. The file under the directory to be displayed in S2 refers to, for example, a picture file (such as a TIF format file or a JPG format file), a document file (such as a Word document or a notepad document), or a video file (such as a wmv format file or an asf format file).
S2 may include S2.1 through S2.3:
S2.1: Determine storage paths of all files under the directory to be displayed in sequence, so as to find corresponding files in the storage paths. For example, a storage path of a file is D:\Translator2\icon\add.png, and the file with a name add.png can be found through the storage path.
S2.2: Parse each file and determine a type of the file. The type of the file includes, for example, a picture file, a document file, and a video file.
2.3: Extract the preview content of each file according to the type of the file, where if the file is a picture file, a thumbnail of the picture file is extracted, if the file is a document file, text content of the document file is extracted, and if the file is a video file, a multiple frames of images of the video file are extracted.
The first area in S3 includes several desktop grids and displays the index list for indexing each file under the directory to be displayed. The desktop grid refers to an independent block for dividing the desktop and bears the functions of arranging and displaying icons. Refer to a diagram of desktop grids shown in
If the file is a picture file, the thumbnail of the extracted picture file is displayed in a corresponding desktop grid in the first area (a first area 10 as shown in
The second area includes a desktop grid. The size of the desktop grid in the second area is greater than the size of the desktop grid in the first area, so that the user can clearly see content of a file displayed in a desktop grid of the second area. The user may select a file by switching files one by one in the file index list displayed in the first area of the desktop, and display preview content of the selected file in the second area of the desktop. When the preview content of the file displayed in the second area of the desktop is selected, the file is demonstrated. Demonstrating the file may include the following three situations.
If the file is a picture file, the thumbnail of the extracted picture file is displayed in the second area of the desktop, such as a second area 20 as shown in
The user may also set a playing control button in the second area of the desktop as shown in
In addition, according to various embodiments, a video player may also be embedded in the second area. When the file is a video file, the video file is played through the set video player, so as to achieve the effect of previewing the video file on the desktop.
