If this option is enabled, WinRAR analyzes the file contents before starting archiving. If several identical files larger than 64 KB are found, the first file in the set is saved as usual file and all following files are saved as references to this first file. It allows to reduce the archive size, but applies some restrictions to resulting archive. You must not delete or rename the first identical file in archive after the archive was created, because it will make extraction of following files using it as a reference impossible. If you modify the first file, following files will also have the modified contents after extracting. Extraction command must involve the first file to create following files successfully.

It is recommended to use this option only if you compress a lot of identical files, will not modify an archive later and will extract an archive entirely, without necessity to unpack or skip individual files. If all identical files are small enough to fit into compression dictionary, solid archiving can provide more flexible solution than this option.

Supported for RAR 5.0 archives only.

大致意思是，在压缩前分析，然后发现大于64KB的相同文件部分，就存储第一个发现的块，以后的块作为参考（建立索引a，创建内置链接啊等等）来存储信息，这样可以减少一些压缩包的大小，但是这要求你以后不能修改压缩包的第一个参考文件，言下之意，你不能在以后再次修改压缩包，解压的时候是整个压缩包一次性解压，如此而已。
