## Abstract

A system described herein may provide a technique for compressing sets of files using a packet-based conversion algorithm. The algorithm may compress and decompress files using a packet-based approach, whereby packet-sized sections of file data are compressed and arranged in a specified order such that the sections may be retrieved, decompressed, and reassembled to restore the original files as needed. The packet-based approach may allow for the size of a file set to be dramatically reduced, while the resulting compressed data may not be easily accessed by unauthorized entities. Compression and decompression may utilize a pointer associated with each file in the set of files. The pointer may be generated based on data associated with a file, such as file name, size, and/or other attributes or metadata. The compressed packets may be arranged relative to the pointer within a compressed file such that the packets may be identified and decompressed.
