In the process of viewing the picture, if you put the mouse over the picture, you can generate a larger thumbnail in the lower part.

Longhron has a very interesting feature, that is, "adjust the size of the icon through the folder", you click "Zoom" on the top toolbar Yes, you can also use the slider to adjust to your needs.
WinFS
The first file system used by Microsoft Windows operating system is FAT (File Allocation Table). Since the operating system is 16bit at the time, FAT is also called FAT16. Later, because of the large capacity hard disk. The FAT-supported hard disk partition is only 2GB at most, so it is less and less suitable for hardware development. Therefore, Microsoft introduced a modified version of the file system FAT32; later, due to security needs, and FAT32 performance degradation in large hard disk partitions Very powerful, so Microsoft introduced NTFS (NT File System) on NT core-based operating systems. NTFS supports smaller disk clusters and more advanced features.
now with the further expansion of hard drive capacity, and users to store more files, Microsoft has introduced a new file system --- WinFS. WinFS is a database-based file system that makes it easier for users to find, store, and categorize files. Perhaps in a sense, it can be thought of as an NTFS file system that adds search engine functionality.
the file system is still in the testing period, so there are a lot of shortcomings, the machine up and running slower, but it still has many impressive highlights:
Longhorn network folder above There is a file called "Default Storage" which allows it to be combined with WinFS as if it were a normal file system. If you have a large number of files to drag and store now, then now you have a more flexible way, WinFS will classify the files based on the file attributes it detects.

Figure 16
For example, we drag a folder with 190 images to the "default storage" file Inside the folder, we can see the size of the image, the data type, etc. in the properties. You can query in an interrogated way and use SQL to organize your questions. WinFS databases can support different types. After
finished its advantages, it is the turn of Microsoft to pull the worm:
We have already mentioned, the test machine is very advanced, including 3.2GHz Pentium 4 Processor, 1GB RAM, high speed hard drive. But it took us 45 minutes to copy the 320MB image to the "default storage" folder --- not only very slow, but of course the performance should be improved in the final version over time and technology.
We also met with other more serious problems, such as when we do not have a password to access the network drive, the "default storage" folder will not be accessible. And in the short time we used the operating system, we did not find any tools to modify this database. We hope that in the final version of Longhorn, Microsoft will be able to make the power of WinFS come true and provide tools to repair corrupted databases.
This preview version of the burning program currently does not support DVD + RW file, DVD +/- RW popular imperative, if we can not support it is regrettable, but perhaps we I didn't delve into it, and it's perfect for burning CDs. The features and features are much more advanced than those that come with Windows XP.

The Longhorn preview version is also available to developers when there is a 64-bit version that supports AMD 64-bit processors. So I installed the operating system on a system equipped with the Athlon64 FX-51 processor, and I didn't find any performance leap. At best, it was in parallel with the 32-bit version, but I talked about it in such an early version of the software. Performance obviously doesn't make sense, because there will be a lot of improvements in the future.
In terms of compatibility, we did not do too much testing, just tried to install a very famous first person shooter game - Halo (halo), but unfortunately this game needs DirectX 9.0b, we did not install successfully, so we have to try other games. Earlier we mentioned that the DirectX version on Longhorn is 9.0, but not 9.0a or 9.0b, weird.

Tron 2.0 was installed successfully and played very smoothly and wonderfully.
Microsoft announced the first generation of the operating environment .NET Framework in July 2000, but on October 27, 2003, Microsoft held the "Professional Developers Conference 2003" for Windows professional developers in Los Angeles, USA. PDC 2003)", Jim Allchin, vice president of Microsoft's platform division, revealed that the new version of the .NET Framework was renamed "WinFX."
Figure 19
Figure 20
He said that WinFX will become the main API of Longhorn, WinFX is newer than the current .NET Framework. the three functions ::
(1) screen display "Avalon (codename)",
(2) the use of database technology file system "WinFS (codename)," < BR>
(3) "Indigo (development code)" for the asynchronous communication function of Web services.
new API has more advanced technology, and can be deep-seated use of hardware, software and game development has become much easier. Unfortunately, because it is a new version of the API, compatibility issues with the old version of the API, so that software developers in the Longhorn application must be selected in Win32, .NET Framework and WinFX One. Allchin claims that applications written in the existing Win32 and .NET Framework APIs will work fine in Longhorn. WinFX coverage is larger than the .NET Framework. Some features can only be achieved with WinFX. On the other hand, some applications that use Win32 are sufficient. If you need to use WinFX, you need to restart when installing a new API application. Maybe Microsoft will solve these problems when it comes to the official version.
Microsoft Chairman and Chief Software Architect (CSA) Bill Gates said: "Web Services", "Internet", "the popularity of smart terminals" and "hardware and software innovation "It will promote the progress of software development." In addition, as an important feature of the new era, we have listed "developers who use Web services to build network systems", "software that can use rich digital information more effectively", and "used to improve communication between individuals, teams, and organizations." An epoch-making user interface."
Longhorn (Longhorn) precisely in order to achieve this mission appears, and it is currently in preview version, can achieve roughly Bill aggressively is still unknown, and now it's functionality and performance in a rapidly changing Among them, there has been a lot of progress over Windowx XP, adding a lot of flexibility.
Longhorn has WinFS, WinFX these advanced technical features, as well as through advanced API technology, fully release the performance of hardware, support for hardware acceleration engines, 3D desktop, and perhaps even the future it cool than Apple.
course of Longhorn is now conclusive, talk about whether it is a successful product too early, because officially released until 2006, long wait, perhaps in time 3.2GHz processor is already unbearable Loaded. Microsoft has created a glorious past for mankind, and in the future humans will change Microsoft. Microsoft can't be invincible, but it can bring us more wonderful products in the competition. Why not?
