The following table enumerates the possible values:
| Compression type | Description |
|---|---|
zcStored
|
The file is stored without compression. |
zcShrunk
|
The file is shrunk. |
zcReduce1
|
The file is reduced with a compression factor of 1. |
zcReduce2
|
The file is reduced with a compression factor of 2. |
zcReduce3
|
The file is reduced with a compression factor of 3. |
zcReduce4
|
The file is reduced with a compression factor of 4. |
zcImplode
|
The file is imploded. |
zcTokenize
|
The file is compressed using the Tokenizing compression algorithm. |
zcDeflate
|
The file is deflated. |
zcDeflate64
|
The file is deflated in an enhanced way, using Deflate64. |
zcPKImplode
|
The PKWARE Data compression Library Imploding method is used. |
zcBZIP2
|
The file is compressed using a BZIP2 algorithm. |
zcLZMA
|
The file is compressed using a LZMA algorithm. |
zcTERSE
|
The file is compressed using IBM TERSE compression method |
zcLZ77
|
