『楼 主』:
压缩工具比较

发信人: COMMAN (P.P), 信区: DOS
标 题: 压缩工具比较
发信站: BBS 水木清华站 (Sat Nov 8 12:09:08 1997)
以下是我对压缩工具的看法
AIN 速度快，压缩比高，使用较灵活，但功能少，其文档是用指针来指示的，
因此一个文档中一旦有一点坏数据，后面的文件全部解错，
另外据同学说，还见过一次 AIN 解压错误的情况。
RAR 界面好，速度居中，压缩文档有两种，Solid 类型于 AIN 类似, 压缩比高但
易坏， Normal类 与 Arj 类似，压缩比不高但安全，前面有人说 RAR 全部解错
是用了 Solid 文档 (默认) , 用 Normal 类型即可获得比 ARJ 高的压缩比和速度
PKZIP 是我最讨厌的文件， 非常罗嗦，虽然速度快，但其似乎有内部 Bug,
我至少见过两次压缩错误，(去看看 Ucdos 5.0 演示版就知道了)
ARJ 太老了， 速度慢得有水平，除了 2.55 版可支持 Win95 长文件名外，几乎
没什么可取的了。
Winzip 好象不错，但我没仔细研究过。至于 Lha,Zoo,Arc,Pak... 还是免谈吧！
我最喜欢 Ain , 其次 Rar , 其次 Winzip...

Subject: Comparison of Compression Tools
Posted: BBS Tsinghua Station (Sat Nov 8 12:09:08 1997)
The following are my views on compression tools
AIN is fast, has a high compression ratio, and is flexible to use, but has few functions. Its documentation is indicated by pointers, so once there is a bit of bad data in a document, all subsequent files are decompressed incorrectly. Also, according to classmates, I have seen a case of AIN decompression error once.
RAR has a good interface, moderate speed. There are two types of compressed documents. The Solid type is similar to AIN, has a high compression ratio but is easy to be damaged. The Normal type is similar to Arj, has a low compression ratio but is safe. Someone mentioned earlier that RAR all decompressed incorrectly because it used the Solid document (default). Using the Normal type can obtain a higher compression ratio and speed than ARJ.
PKZIP is the file I hate the most. It is very wordy. Although it is fast, it seems to have internal bugs. I have seen at least two compression errors. (Just take a look at the Ucdos 5.0 demo version to know)
ARJ is too old. It is extremely slow. Except that version 2.55 can support Win95 long filenames, there is almost nothing to recommend.
Winzip seems good, but I haven't studied it carefully. As for Lha, Zoo, Arc, Pak... it's better to forget about them!
I like Ain the most, followed by Rar, followed by Winzip...

据我所知现在的压缩软件里是
winace2.* 的压缩率最高！
winrar3.* 第二
winzip 垫低
wincab吗！
很难说当winrar和winace没有钩上Solid时
压缩率没有它高，
也就是说当文件的个数多的时候。
winrar和winace压缩率高，
当单个文件时wincab就称老大了！（因为这是Solid跟没钩过一样吗）
还有就是win98的安装文件就是用cab格式做的，
所以用cab压缩包时，
就可以直接用起动盘中的EXTRACT.EXE来解压缩了！
也就不需要别的什么解压软件了！
最后是winimg
它的压缩率可能没有以上的任何一种软件高。
也好像没有任何一种别的软件可以解开IMG格式的文件。
可是，它在压缩word文本和jpg这两种文件时却又十分惊人的压缩率。
这是因为winimg对这两种文件格式进行了特殊的优化所致！
还有就是因为除了它本身，
没有任何一种别的软件可以解开IMG格式的文件。
所以它所做的自解压文件的安装文件的安全性，
和防反汇编能力也就强多了！
典型的方法时写一个批处理文件，
然后生成一个自解压文件在解压后自动运行这个批处理文件。
如果觉得还不安全就在用winrar
生成一个带ico图标的自解压文件，
在自解压后自动运行这个exe文件。
这样就更有迷惑性了！
总体评价wincab为最建议的，
接下来时winace和winrar
如果有特殊要求的就用winimg
winzip垫低！
As far as I know, among current compression software, winace 2.* has the highest compression ratio! winrar 3.* is second, and winzip is the lowest. What about wincab! It's hard to say. When winrar and winace don't have Solid hooked up, their compression ratio isn't as high as it. That is to say, when there are many files, winrar and winace have a high compression ratio. When it's a single file, wincab becomes the boss! (Because this is like Solid not being hooked up?) Also, the installation files of win98 are made in cab format, so when using cab compression packages, you can directly use EXTRACT.EXE in the boot disk to decompress, so you don't need other decompression software. Finally, winimg. Its compression ratio may not be higher than any of the above software. Also, it seems that no other software can unzip IMG format files. However, it has extremely amazing compression ratios when compressing word texts and jpg files. This is because winimg has carried out special optimizations for these two file formats! Also, because except for itself, no other software can unzip IMG format files. So the security of its self-extracting installation files and the anti-disassembly ability are much stronger!
The typical method is to write a batch file, and then generate a self-extracting file to automatically run this batch file after decompression. If you think it's not safe enough, then use winrar to generate a self-extracting file with an ico icon, and automatically run this exe file after self-extraction. This is more confusing!
Overall evaluation: wincab is the most recommended, then winace and winrar. If there are special requirements, use winimg. winzip is the lowest!

谁来详谈一下可执行文件的压缩工具呀
有些压缩比更高呀
Who can talk in detail about executable file compression tools? Some have higher compression ratios.

CABARC.EXE也不错呢，制作CAB格式，压缩比相当高的。
CABARC.EXE is also quite good, it creates CAB format with a rather high compression ratio.

对可执行文件的压缩率，应是UPX最高，WWPACK次之，然后是AIN的EXE压缩工具。再下应该是PKLITE和DIET了，最低是LZEXE和EXEPACK，其他我不熟悉或未用过。
PKLITE和DIET可压缩COM文件，PKLITE2以上可压缩WIN3X文件。UPX可压缩WIN9X文件。
The compression ratio of executable files should be that UPX is the highest, WWPACK is next, then AIN's EXE compression tool. Next should be PKLITE and DIET, and the lowest are LZEXE and EXEPACK. Others I am not familiar with or have not used. PKLITE and DIET can compress COM files, and PKLITE 2 and above can compress WIN3X files. UPX can compress WIN9X files.

是APack最高呢......

Is APack the highest......

我用APack跟UPX试过，是UPX高一点，如果是APACK高的话是不是还要加其它参数？
I tried with APack and UPX, and UPX is a bit higher. If APACK is higher, do I need to add other parameters?

aPack有时比UPX更高。但用aPack压缩的文件却有个大BUG，正如我上次所说的那样。
aPack is sometimes higher than UPX. But the files compressed with aPack have a big BUG, just as I said last time.

数据文件的压缩还是用WinImp吧，现在是1.21版，要图方便就用RAR，ZIP最好扔掉，不要再提起，把它忘记。
For compressing data files, still use WinImp. It's version 1.21 now. If you want convenience, use RAR. Just throw away ZIP and never mention it again, forget about it.

记得DOS下有个叫“ACB”的东西，好像压缩比很高。
I remember there was something called "ACB" under DOS, which seemed to have a very high compression ratio.

我喜好CAB的一个主要原因就是
CAB文件到那里都能打开，
不需要任何解压软件。
现在win98的系统实在是太多了！
One of the main reasons I like CAB is that
CAB files can be opened anywhere,
without any decompression software.
Now there are really too many Win98 systems!
