------------------------------------------
[~aviroop123]
What you're asking for is a large complex task.
NIO file systems is not the goal of Compress.
Support for NIO file systems will be done through Commons VFS. I have a branch
saved somewhere to get started but nowhere near done.
> Support for ZipFileSystem equivalent for Zstd
> ---------------------------------------------
>
> Key: COMPRESS-704
> URL: https://issues.apache.org/jira/browse/COMPRESS-704
> Project: Commons Compress
> Issue Type: Improvement
> Components: Compressors
> Affects Versions: 1.28.0
> Reporter: Aviroop Pal
> Priority: Major
>
> Zstd support seems to be added in 1.28.0. But one of the major issues for us
> to adopt zstd + zip is the lack of FIleSystem support similar to
> [https://docs.oracle.com/javase/8/docs/api/java/nio/file/FileSystem.html]
> The current implementation of FileSystemProvider:
> [https://commons.apache.org/proper/commons-io/apidocs/org/apache/commons/io/file/spi/FileSystemProviders.html]
> returns the FileSystem from java.nio.file which doesn't support the zstd
> compression method. I'm getting "invalid CEN header (unsupported compression
> method: 93)" and the current implementation suggest only STORED(0) and
> DEFLATED(8) methods are supported.
