uncozip

This is a command and package to UNzip COrrupted ZIP file that does not have the central directory records.

Even when the archive is so large that zip -FF Corrupted.zip --out New.zip fails, sometimes uncozip succeeds.
( For example, the case Corrupted.zip is larger than 4GB )

The uncozip is also useful on non-Windows OSes to unpack archives with non-UTF8 filenames such as Shift_JIS. (uncozip -decode Shift_JIS foo.zip)

Usage

uncozip {OPTIONS} ZIPFILENAME [list...]

uncozip {OPTIONS} - [list...] < ZIPFILENAME

uncozip {OPTIONS} < ZIPFILENAME

• -d string the directory where to extract
• -debug Enable debug output
• -strict quit immediately on CRC-Error

Unlike "archive/zip", uncozip can

• read an archive from io.Reader.
  ( "archive/zip" requires archive's filename¹ or io.ReaderAt and size information² )
• handle encrypted archive.
  ( You have to call RegisterPasswordHandler )
• decode filename from any encoding
  ( You have to call RegisterNameDecoder )
