Bit 0: If set, indicates that the file is encrypted.

Bit 3: If this bit is set, the fields crc-32, compressed size and uncompressed size are set to zero in the local header. The correct values are put in the data descriptor immediately following the compressed data.

Note: PKZIP version 2.04g for DOS only recognizes this bit for method 8 compression, newer versions of PKZIP recognize this bit for any compression method.

Bit 4: Reserved for use with method 8, for enhanced deflating.

Bit 5: If this bit is set, this indicates that the file is compressed patched data.

Note: Requires PKZIP version 2.70 or greater.

Bit 6: Strong encryption. If this bit is set, you MUST set the version needed to extract value to at least 50 and you MUST also set bit 0. If AES encryption is used, the version needed to extract value MUST be at least 51. See the section describing the Strong Encryption Specification for details. Refer to the section in this document entitled "Incorporating PKWARE Proprietary Technology into Your Product" for more information.
