Compression

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Stored = 0

Store the file as is

Shrink = 1

Method 1 Shrink

ReduceFactor1 = 2

Reduce with compression factor 1

ReduceFactor2 = 3

Reduce with compression factor 2

ReduceFactor3 = 4

Reduce with compression factor 3

ReduceFactor4 = 5

Reduce with compression factor 4

Implode = 6

Implode/explode

TokenizingCompression = 7

Reserved for Tokenizing compression algorithm

Deflated = 8

Compress the file using Deflate

Deflate64 = 9

Compress the file using Deflate64.

PkwareDataCompressionImploding = 10

PKWARE Data Compression Library Imploding (old IBM TERSE)

Reserved11 = 11

Reserved by PKWARE

Bzip2 = 12

Compress the file using BZIP2

Reserved13 = 13

Reserved by PKWARE

Lzma = 14

Compress the file using LZMA

Reserved15 = 15

Reserved by PKWARE

CmpscCompression = 16

IBM z/OS CMPSC Compression

Reserved17 = 17

Reserved by PKWARE

IbmTerseNew = 18

File is compressed using IBM TERSE (new)

IbmLz77 = 19

IBM LZ77 z Architecture

DeprecatedZstd = 20

deprecated ZSTD

Zstd = 93

Compress the file using ZStandard

Mp3 = 94

MP3 Compression

Xz = 95

Compress the file using XZ

Jpeg = 96

JPEG variant

WavPack = 97

WavPack compressed data

Ppmd = 98

Compress the file using PPMd

Aes = 99

Encrypted using AES.

The actual compression method has to be taken from the AES extra data field or from ZipFileData.

Unknown(u16)

Unsupported compression method
