You plan to use uncompressed assetbundle in your project, so you need to pack the assetbundle manually because you have previously packaged an analysis of 100,000 cold jokes, so this time firmly select the LZMA compression algorithm to compress the Assetbundle.

Note:

Because I do not know lzma how to compress and unzip the folder, so it is planned to upk the folder into UPK file, and then Lzma compression. Unzip the words first extract the UPK file, and then read the UPK file to release the source files.

LZMA official website Download SDK

Http://www.7-zip.org/sdk.html

After downloading the 7zip in C # directly into unity, then Setting.cs will error, delete it.

Note:

the LZMA SDK source code in this example has been modified by me.
