    • A method of dynamically creating a two-stage self-extracting archives. During the archive creation process the executable code segments for inverse algorithms are selectively added to the self-extracting archive, but only for those algorithms applied during archive creation. This results in a considerably smaller size of the self-extracting archive. Additional space savings can be achieved by reprocessing the original data to eliminate the use of any algorithm applied in the archive creation which resulted in less savings than the additional size of the corresponding inverse algorithm. The selected inverse algorithms are themselves compressed. A compact inverse algorithm is provided as ready-to-execute code, which restores the selected inverse algorithms to an executable state, and then causes them to be executed on the compressed file data.
    • 一种动态创建两阶段自解压存档的方法。 在归档创建过程中,用于逆算法的可执行代码段被选择性地添加到自解压缩存档,但仅适用于在归档创建期间应用的那些算法。 这导致自解压档案的大小更小。 通过重新处理原始数据可以实现额外的空间节省,以消除使用归档创建中应用的任何算法,这导致比相应逆算法的附加大小更少的节省。 所选择的逆算法本身被压缩。 提供了一种紧凑的逆算法作为可执行代码,将所选择的逆算法恢复为可执行状态,然后使其在压缩文件数据上执行。
