Each entry in the archive has certain properties, for example: file name, compression method, encryption method, file size before compression, file size after compression, CRC32 and others. ### Documentation: #### Overview of methods of the class `\PhpZip\ZipFile` - [ZipFile::__construct](#zipfile__construct) - initializes the ZIP archive. - [ZipFile::addAll](#zipfileaddall) - adds all entries from an array. - [ZipFile::addDir](#zipfileadddir) - adds files to the archive from the directory on the specified path without subdirectories. - [ZipFile::addDirRecursive](#zipfileadddirrecursive) - adds files to the archive from the directory on the specified path with subdirectories. - [ZipFile::addEmptyDir](#zipfileaddemptydir) - add a new directory. - [ZipFile::addFile](#zipfileaddfile) - adds a file to a ZIP archive from the given path. - [ZipFile::addSplFile](#zipfileaddsplfile) - adds a `\SplFileInfo` to a ZIP archive. - [ZipFile::addFromFinder](#zipfileaddfromfinder) - adds files from the `Symfony\Component\Finder\Finder` to a ZIP archive. - [ZipFile::addFilesFromIterator](#zipfileaddfilesfromiterator) - adds files from the iterator of directories. - [ZipFile::addFilesFromGlob](#zipfileaddfilesfromglob) - adds files from a directory by glob pattern without subdirectories. - [ZipFile::addFilesFromGlobRecursive](#zipfileaddfilesfromglobrecursive) - adds files from a directory by glob pattern with subdirectories. - [ZipFile::addFilesFromRegex](#zipfileaddfilesfromregex) - adds files from a directory by PCRE pattern without subdirectories. - [ZipFile::addFilesFromRegexRecursive](#zipfileaddfilesfromregexrecursive) - adds files from a directory by PCRE pattern with subdirectories. - [ZipFile::addFromStream](#zipfileaddfromstream) - adds an entry from the stream to the ZIP archive. - [ZipFile::addFromString](#zipfileaddfromstring) - adds a file to a ZIP archive using its contents. - [ZipFile::close](#zipfileclose) - close the archive. - [ZipFile::count](#zipfilecount) - returns the number of entries in the archive. - [ZipFile::deleteFromName](#zipfiledeletefromname) - deletes an entry in the archive using its name. - [ZipFile::deleteFromGlob](#zipfiledeletefromglob) - deletes an entries in the archive using glob pattern. - [ZipFile::delete
