Further information
1. The
filters argument has a similar structure as the corresponding argument of procedure
findfiles except that wildcard characters
"*" and
"?" may appear anywhere in a path. A file is extracted if it matches any of the patterns of this list.
2. When evaluating the filters, file name matching is achieved using function
pathmatch and differences may be observed depending on the operating system (
e.g. file names are case sensitive under Posix systems but not under Windows).
3. This implementation only supports the standard Zip format (only 32bit and basic encryption algorithm) and symbolic links are silently ignored if the system does not support them.
4. By default file names are expected to be represented according the current system encoding in the archive. To select a different encoding use the enc: file name prefix (see Section
Character encoding of text files) on the archive name (
e.g.
"enc:utf-8,myarc.zip").
