To expose the fraud: WinRAR to compress 775MB 13.4MB



I believe many people probably remember about a year ago was used to compress an empty file 100MB 1MB, then put into the 1.44MB floppy disk, and led to numerous spittle farce Why?

Recently, the author of a well-known in the country to see such a post Forum: A Russian's ARPG game to a 755MB compressed file size is only 13.4MB! From 755MB to 13.4MB, which is amazing what a compression ratio of Oh! Indeed a ripple, flew forum attracted many users of the incredible evaluation. In the end is not really that amazing? Is is a hoax? According to the post by the prompt to download the file address, I also curious to start the following test.

Witnessed

Click http://24apr.vega-service.ru/images/sacredCD1.exe (extract password erased), this "magic" of the file downloaded to the local hard disk, open its properties, and found that we usually do not use the Common 7.zip self-extracting file format, and size really is only 13.4MB, compression rate of 1%!






Figure 1:755 MB compressed file turned out to be 13.4MB!?






Figure 2: such a high compression ratio and amazing!

We should know that the latest version of WinRAR has supported 7.zip file format, directly with the latest version of WinRAR to unpack, get three files, one of the MDF file size is really 755MB, if played Sacred (Sacred Discipline) This game should know that this is CD1 mirror, can be used Deamon load.






Figure 3: File size

I was not interested in the game itself, but know the MDF file compression ratio is not likely so high, why have such a high compression rate? And extracting such a large 755MB file, even when less than 1 minute!






Figure 4: The shocking speed

WinRAR by this author tried to achieve the highest compression ratio method, to extract out of the 755MB file to re-compress it again.

Tip: How to get the highest compression rate of WinRAR?

1. Use the "best" compression, run in WinRAR "Settings 鈫?Options 鈫?Options 鈫?Create the default compression compression configuration" open "to set the default compression options" window, in the "General" tab of "compression "field select the" best. "

2. On the compressed file or the same type of large number of small files, you can in the "Archive options" bar check "to create a fixed file file", and do not use the recovery record, in the "default compression option" is not checked " set to resume recording. "

3. With the best dictionary file: "default compression options" window, switch to the "Advanced" tab, click the "compression" button in the pop-up window "conventional compression column," select "Dictionary File" of the size of the largest "4096KB".

The author has compressed many times the size of the results obtained are between 16MB ~ 20MB, and compressed into the compression rate of 13.4MB is quite close, and to compress the time required to less than 4 minutes! "God" a?






Figure 5: We personally compressed, it has also to be such a high compression ratio?






Figure 6: re-compression

However, this is often used for file compression is not confused by the author, can be sure that the original author of the document source tampered. In the absence of the game's original CD, so CD can not be compared with CDCheck software to compare the before and after the two CD. So, I thought of using 16-bit text editor UltraEdit to directly analyze the source code. Open the 755MB file took a lot of time and found that most of the source code file is 00!, This file is a compressed air-scam!






Figure 7: The file's source code actually is 00! Empty file?!

For a long time, due to size, technology, capital, management, and various constraints, Nantong private shipbuilding enterprise to build barges, mainly general cargo ships and other vessels, and high technology, high added value, large tonnage of high-end ship, few involved. Today, however, is precisely because of COSCO, "Double Star", Nantong private enterprises ship owners have a dream of transcendence.

But this was not enough, the various elements of productive private enterprises ship, eager to faster and more smooth to pour. RSHI President Chen Qiang said that in the construction of the ship mortgage is international practice, but it does not work in the domestic shipbuilding enterprises urgently need financial capital. In addition, Shanghai, Nantong ship test has an advantage, but the procedures are more, if the additional delivery of the Vessel base in Shanghai, ship exports will flow. General Manager Wang Zhinan born in Hong Kong shipping companies argued that the development of the shipbuilding industry, industry associations have existed in name only. In re-associations, should reflect the status of small and medium private enterprises, so that equal communication.

In his view, the development of shipbuilding industry, ship equipment industry to be bigger and stronger. Efforts to promote the shipbuilding industry supporting Park to create Marine Equipment industry development platform is essential.

Low level of marine equipment at home, is striving to be China Nantong "shipbuilding city" of the "bottleneck." Value composition from a single vessel, combined with the current experience of the city part of the shipbuilding enterprise data analysis, material costs account for 80%% 10%% of labor costs and other costs 10%%. In accounting for the bulk of the materials, the ship manufacturing companies supporting the city's rate of about 8%%, outside the city matching rate of 20%%, matching rate of 72%% abroad, with Europe and other regions matching rate of 90%%, far from home. Only final assembly and integration, there is no supporting simultaneous development of industry, shipbuilding industry can only be "short-legged economy" can not be enduring.

According to reports, the production base in Nantong Zhenhua Port Machinery total investment of 30 billion yuan put into production, annual output of 100 bridge crane, bridge container field 200 and a large offshore oil platform 50, the annual turnover of 1.5 billion U.S. dollars above. Among them, single-gear box, a project covering about 500 acres, completed an annual output of 20,000 sets of various major gear box, the annual output value of 1.6 billion or more, can significantly enhance China's own brands of large capacity of gear box.

Shipping supporting Gangzha District Industrial Zone, Development Zone, Industrial Park, marine equipment, and Qidong Binhai Industrial Park construction of ships, will greatly promote the marine equipment manufacturing industry cluster development, coordinated development and leapfrog development. Yong Du, deputy director of the Urban Economic and Trade Commission said the DPRK is currently the three parks have been approved by the Work Committee for National Defense, is expected to become a national ship supporting industrial park.
