The majority of Minecraft maps that you can download will likely be archived within a .zip or .rar file. The folders and files contained in this archive must be extracted into your Minecraft saves folder, this allows Minecraft to detect the map.
You will need a file archiver program to do this, such as 7-Zip (Windows only) which is free. If you have a Mac, the "Archive Utility" built into OS X will be able to open .zip files by right-clicking on the .zip and selecting "Open With > Archive Utility", but you will need a program such as The Unarchiver for .rar files.

ZIP files generally use the file extensions .mw-parser-output .monospacedfont-family:monospace,monospace.zip or .ZIP and the MIME media type application/zip. ZIP is used as a base file format by many programs, usually under a different name. When navigating a file system via a user interface, graphical icons representing ZIP files often appear as a document or other object prominently featuring a zipper.
WinZip, starting with version 12.1, uses the extension .zipx for ZIP files that use compression methods newer than DEFLATE; specifically, methods BZip, LZMA, PPMd, Jpeg and Wavpack. The last 2 are applied to appropriate file types when "Best method" compression is selected.
The File Explorer in Windows XP does not support ZIP64, but the Explorer in Windows Vista and later do. Likewise, some extension libraries support ZIP64, such as DotNetZip, QuaZIP and IO::Compress::Zip in Perl. Python's built-in zipfile supports it since 2.5 and defaults to it since 3.4. OpenJDK's built-in java.util.zip supports ZIP64 from version Java 7. Android Java API support ZIP64 since Android 6.0. Mac OS Sierra's Archive Utility notably does not support ZIP64, and can create corrupt archives when ZIP64 would be required. However, the ditto command shipped with Mac OS will unzip ZIP64 files. More recent[when?] versions of Mac OS ship with info-zip's zip and unzip command line tools which do support Zip64: to verify run zip -v and look for "ZIP64_SUPPORT".
A Seek-Optimized ZIP file (SOZip) profile  has been proposed for the ZIP format. Such file contains one or several Deflate-compressed files that are organized and annotated such that a SOZip-aware reader can perform very fast random access (seek) within a compressed file. SOZip makes it possible to access large compressed files directly from a .zip file without prior decompression. It combines the use of ZLib block flushs issued at regular interval with a hidden index file mapping offsets of the uncompressed file to offsets in the compressed stream. ZIP readers that are not aware of that extension can read a SOZip-enabled file normally and ignore the extended features that support efficient seek capability.
Some development libraries licensed under open source agreement are libzip, libarchive, and Info-ZIP. For Java: Java Platform, Standard Edition contains the package "java.util.zip" to handle standard .ZIP files; the Zip64File library specifically supports large files (larger than 4 GB) and treats .ZIP files using random access; and the Apache Ant tool contains a more complete implementation released under the Apache Software License. 041b061a72
