Sample code to convert from CAB to ZIP
The conversion of a CAB archive into diverse formats necessitates a systematic and meticulous approach. Typically, CAB archives house an array of files or records, each containing valuable data. To facilitate this transformation into formats like GZ (Gzip), LZ (Lzip), Z (Unix Compress), XZ (XZ Utils), and BZ2 (Bzip2), a widely embraced strategy involves the initial consolidation of these contents into a ZIP (Zipped Archive with Gzip Compression) format.
This methodology closely aligns with established practices within Linux environments, where ZIP archives are recognized as versatile containers. Throughout the conversion process, each individual file or record within the CAB archive is scrupulously organized within a unified ZIP archive. This ZIP archive serves as a coherent repository, diligently preserving the original file structures and associated metadata. This encapsulation into the ZIP format streamlines the subsequent application of diverse compression algorithms and formats.
The preference for ZIP as an intermediary format is rooted in its inherent simplicity and exceptional compatibility across various Unix-like operating systems. Its capability to group files together without immediate compression application makes it a pragmatic choice. Following the successful packaging into ZIP, subsequent compression operations can be applied to generate the desired output formats, encompassing GZ, LZ, Z, XZ, or BZ2.
In essence, this comprehensive process ensures the efficient transformation of the data initially housed in the CAB archive into a spectrum of formats, providing adaptability and compatibility across various use cases.
Convert from CAB to ZIP - C#:
using (Archive zip = new Archive())
{
using (CabArchive cabArchive = new CabArchive("archive.cab"))
{
for (int i = 0; i < cabArchive.Entries.Count; i++)
{
var ms = new MemoryStream();
cabArchive.Entries[i].Extract(ms);
ms.Seek(0, SeekOrigin.Begin);
zip.CreateEntry(cabArchive.Entries[i].Name, ms);
}
}
zip.Save("output.zip");
}
