Description

Reads a file from a .zip archive.

There are four overloads of this procedure, depending on the file representation and the output mode.

• FileName indicates the name of the file in the .zip archive.

• Bytes represents the output bytes (used by the first two overloads).

• Index is the index of the file in this .zip archive.

• Stream is the output stream (used by the last two overloads).

• LocalHeader is the local file header.

The overload procedures that take an integer as a parameter are useful when the .zip archive contains duplicate file names.

To track the progress of the operation, use OnProgress.
