During this time, a "n-one" wind was thrown. The first time the Win2000 Pro, Server and AdvServer made a CD. I thought it was simple to engrave three systems installation. Above, later calculated, there are less than 900m-1G data, it is not possible. Let's take a look at it, discovering the practice very fresh: In fact, in the three versions of the Win2000, there is a lot of files, especially the language package / font (I386 / LANG directory), and writing panels. Application, and that 50M driver.cab. Different are just relatively small system files. This N-shaped disc passes the ISO image through special processing, repeated files, and actual data on the disc, by similar to the modified optical disc catalog table, let different directories / files points to the same data area. After completing the ISO modification, then the disc. In this way, it will save space and make each directory look independent and complete. So how much is it? Made an experiment, I have a Win2k Pro installation directory and an ADV Server installation directory, respectively, 260m and 280m, respectively. (In order to save space, I have removed other languages except the Chinese traditional Chinese, like Korean Japanese Arabic, I can use it in my life). If the two directories are simply engraved on a disk, it will account for about 540m. The method of using n is used, "the same file is only processed once", and only about 340m is merged. According to this figure, there are 70-75% of the two! Different parts only account for 25% -30% of their own! According to this numeral, even if the Server is added, the last size should only be 400-450m, 800M, which is added, almost half. If you don't want to save three of the WIN2000 separately with three CDRs, you can consider yourself a N-one disc. Speaking of not only the backwardness of the DOS / WIN file system. Unix / Linux provides a function of symbolic connection from the first place, a simple LN command to complete the above work, and in DOS / WIN, this operation must be made by modifying ISO with special software, and this structure It can't be exist on the hard disk because it seems "Cross-Connection" in all disk check software for DOS / WIN, will be corrected. Ok, don't be far away. If you come back, it is easy to understand this way. Do you actually do it? The key is how the "same file" is judging. It is very troublesome by manual. In fact, Microsoft provides a tool, called CDImage, specializing in this. Plus a -O parameter, you can implement the "Automatic Optimization" function. Ms many internal release versions are "squeezed" on a plate. This gadget is extracting only 70K. Of course, it is not only used to do Win2000 N-one. Use it to use it to use it for all "large number of files". But ... seeming to this situation, don't ... Do you have any example? Specific approach: 1, build a directory, see it as the root directory of the CD, let all the content you want to put, such as this directory called C: / Ewin3in1, there is
C: / EWIN3IN1 / PROC: / EWIN3IN1 / Serverc: / EWIN3IN1 / ADVSERVER directory, respectively corresponds to three Win2000 versions, respectively. Now check the directory properties, you should be 800M or more, you cannot be placed on a disc. 2, now use the CDImage program to run in another directory (you want to generate a directory of the ISO file):
CDIMAGE -LWIN2K3IN1-T08 / 22/00, 00: 00: 00 --H -N -O -M C: / EWIN2K MY3IN1.ISO Direct Run CDIMAGE will display parameter description. The following is a brief explanation of common parameters: -l: (is a jkl L, not IBM i) This is the disc's volume-T: set all files to specify the time, looks very professional - Hide file -n: Allow long file names-O: This is the most important, CDImage's essence is it. Automatically determine duplicate files, only processing once for duplicate files, and automatically modify the relevant file points. By default, the file size and MD5 algorithm are used (I don't know much, it is probably the method of checksum.) The accuracy is quite high from the probability angle, but it is not "one byte comparison". If you ask for bytes, use -oc parameters. However, the speed is extremely slow. -m: If this parameter is not added, it will not produce a ISO image of greater than 650m C: / EWIN2K: This is the root directory of the disc. CDIMAGE will construct a disc catalog structure with this directory, and C: / EWIN2K / Pro on the hard disk will turn into a disc's x: /promy3in1.iso: This is the name of the last generated ISO file. It is already optimized. 3. Finally, simply use the burning software (such as the CREATE DIM Image of Easy CD Creator) to enter the ISO to a disc. At this time, our N will finish it. Of course, this disk is just simply putting three installation directories and cannot be started. The ideal case is that the disc is automatically started as an image of 2000. (This already done it), more ideal case is to start the menu, you can choose to install Pro / Server or AdvServer, then automatically call the corresponding Setup.
This kind of disk is of course shortcomings, and it is obvious: 1. If the disc has a certain place, just a system file of "sharing", then 3 Win2000 will be scrapped and cannot be installed. The normal disc just damages the version to which the file belongs. 2, it is best to have an optical disk burner, this ISO mirror, use WinImage solution, WinImage does not know this modified structure, which will solve all files on the hard disk by the directory table, the same file Several copies were copied. It is equivalent to the state of the restore to optimize. I like the EWIN 6 combined, I seem to have 1.9G. However, it is not important to say that these disadvantages are not important.
