Fast pressure is a free compression software, is the first with independent compression technology of domestic software, its own compression format "KZ" has a large compression ratio and super fast compression decompression speed, compatible with RAR, zip and 7Z, such as more than 40 kinds of compressed files, in addition, can also be used as

In the traditional compressed file, solid compaction can not only provide file compression ratio, but also in the folder compression, it is particularly important, and some of the recent use of fast pressure users want to use solid compression, and do not know how to operate, so the small series here for everyone to bring a detailed operation method, the need for users to learn quickly!

Is there a way to use php to directly download files in the compressed package with php_zip.dll extension without any pressure? the file name can be read, but this function has never been very important, if it succeeds, it may save a lot of resources and space .... I know this website has this function: http://www.bvbcode.com/cn/0ij1cmk2. Is there
Fast pressure is a multi-function file compression software, the software supports the compression and decompression of common files, and can support the decompression of KZ, ZIP, 7Z, RAR, MOU, ACE, ARJ, BZ2, CAB, GZ, ISO, JAR, LZH, TAR, UUE, Z and other format files. However, some users do not know how to use the fast pressure to create compressed files, so the

Therefore, I feel that to reduce the pressure on leaders, we can only achieve this by stripping them of non-critical businesses or functions. To improve leadership, you can only upgrade devices.
In addition, the splitting results of the origina
