Why does the file size become larger than the original after the disc is imaged?

I think some necessary documents have been added

Is it? What kind of mirror software, it's very poorly done.

However, it can be rewritten to the disc using this software. Sometimes the capacity of the disc is also different.

It's a little bigger, but it's just a few MB, and it's basically the same.

It's going to get bigger, but it shouldn't change much.

You can compress a file yourself, and try to find out, depending on how you compress it, some are bigger, some are smaller.

You can send the ISO file to a folder first.,Compress the folder with decompression software.,Try to see if this compressed package has become smaller.。。

Use a USB flash drive or mobile hard disk to store, and copy it to the hard disk for installation when installing the system.

You can go and buy a large-capacity *** burning disk.

5 hours (single-sided, single-layer).

9 hours (single-sided, double-layered).

10 (double-sided, single-layer) hours.

18 (double-sided, double-layered) hours.

Make a USB flash drive to boot what kind of disc to use.

I don't know if you've used alcohol 120% to burn a disc into a virtual orange image file. If you choose ISO, only one image file will be generated (the size of the CD is the size of the CD, but if you choose the MDF format, two image files will be generated (one with the extension, one with the other?). I can't remember that.)

One of them. The MDF file is still the original size, and the other file is sometimes dozens of M, sometimes dozens of K, not necessarily. But if you import it with a virtual optical drive, both files can be run (weird).

I haven't tried this kind of situation where you burn the image file to CD, but is it the reason why you have to import the second file in?

Is it a mistake when copying the file?

Open the bin file and load the image.

It has nothing to do with compression, I believe you should have seen the all-in-one installation CD, this CD is also based on the same principle, an all-in-one CD made with software such as nmake or easyboot (for example, it may be the enterprise version and the personal version of the two-in-one, or it may be the all-in-one version of each language), after loading with ultraiso, you can see the actual size of the disc on the upper right of ultraiso, for example, the ISO of the original SQL Server 4 in1 is only 690M,But what is displayed in UltraISO is2145M,This 2145M is the actual size of the disc,If you save it with Ultraiso at this time,It will destroy the original all-in-one structure (that is, the same file is repeated on the disc no matter how many times,Only the actual storage on the disc once),Of course, the size will be different,In fact, it is saved in this way,It is equivalent to the size that you use Winrar to unzip the original ISO right-click。

Pay attention to the 1398 overload in the upper right corner of the picture you posted, this means that with this all-in-one technology, it actually saves 1398m, take this size and add your previous example, it is basically equal to the size you saved.

Its main use is that some of the contents of the disc can only run while the disc is running, even if you install it on your computer! For example, some game discs, etc., so you have to use the disc every time you use it, which is not good for optical drives! Therefore, it is possible to use disc imagery, that is, to make the content on the disc into a fake disc and save it to the computer, and run it with a virtual CD-ROM drive, just like a real CD, but in fact it is still running the files on the hard disk!

A disc image is a file that reflects the entire contents of a disc. There are many ISO formats for disc images

img bin, nrg mdf, mds, vcd, etc.

Disc images can serve the purpose of protecting discs, and after making the image, you don't need discs, and you don't need optical drives. There is still achievable"Share"purpose. ^_

If the content in your disc is not in these formats, and after putting the disc into the computer, the computer cannot recognize it (you should be able to see if it can be recognized when copying), and there are multiple folders in the CD, and there are some files that you do not recognize, then it means that the disc is burned in a similar way as CD, VCD, etc., then you should use the software to make an image and store it on your computer, and then use the virtual optical drive to load the image, and you can use it; Of course, you can also copy the content directly.,Don't copy all.,You just need to copy the largest folder.,It's what you want.**,These files must be relatively large lead bridge bright.,It can't be a few m or less than 1m.,If you copy to those files, it's wrong to wide.。 Silver.

Because the destroyer disc file is copied to the U disk will have a certain compression loss, resulting in a decrease in the quality of the sensitivity, if you want him to remain unchanged, you have to copy it losslessly, you need to use a special bridge tool.

If it's a directly imported source**file,In**The effect should be a vertical leg-like remainder,If there is a problem you said,It must be that the imported file is not the original file,But after the spike processing again,Compressed。

Because the *** format is compressed, the files on the 2U disk are the source files. The definition of the USB flash drive is much higher than that of the *** disc. I'm also one of the reasons why it's now lower than the D format.

The reading and writing speed is different, and the effect is different.

This may be an attenuation of the signal. Because the USB flash drive does not have *** high definition.

The resolution is not the same, the movie capacity is not the same, and the format of the movie is not the same.

Because the **format quality in the rice U disk is not good, the clarity is not good, and the source of the film is not clear, how can a clear ** be released? There is also a relationship between the decoder of the macro band *** and the decoding of the bending method.

This one is very simple. If you need the same quality, you can only make your *** disc into an ISO image or other format image file through the software. Then on the computer, the virtual disc drive was broadcast, and Zheng Fangdong socks were carried.

After the test is on the USB flash drive, the format is compressed, and the display effect is not so good.

It's a matter of device resolution!

The mobile phone can't be turned on when it has power, it may be that the inner limbs are full, ** things are too much to accompany the spine, or it may be for other reasons, the solution can be flashed, but there is a risk in flashing, and it is easy to lose important information, such as customer ** number, chat history, etc., the most good suggestion is to take the mobile phone repair shop to overhaul it...

This is the reason for the conversion settings.

The disc is primary. VOB files, pretending to be bent. ifo file and. bup file...VOB files are used to store all audio and data in MPEG-2 format.

After copying, it will always be distorted, why is there a pirated version, the original version?

1 U disk read speed.

2 There is no format conversion.

Copy the contents of the disc to the computer with QQ video

I was just about to ask that question.
