They are tracked for each file by NTFS and by various - /// Unix filesystems, but they are also tracked by other filesystems, too. - /// The key point is that the times are formatted in the zip file - /// in the same way that NTFS formats the time (ticks since win32 epoch), - /// or in the same way that Unix formats the time (seconds since Unix - /// epoch). As with the DOS time, any tool or library running on any - /// operating system is capable of formatting a time in one of these ways - /// and embedding it into the zip file. - /// - /// - /// - /// These extended times are higher precision quantities than the DOS time. - /// As described above, the (DOS) LastModified has a precision of 2 seconds. - /// The Unix time is stored with a precision of 1 second. The NTFS time is - /// stored with a precision of 0.0000001 seconds. The quantities are easily - /// convertible, except for the loss of precision you may incur. - /// - /// - /// - /// A zip archive can store the {C,A,M} times in NTFS format, in Unix format, - /// or not at all. Often a tool running on Unix or Mac will embed the times - /// in Unix format (1 second precision), while WinZip running on Windows might - /// embed the times in NTFS format (precision of of 0.0000001 seconds). When - /// reading a zip file with these "extended" times, in either format, - /// DotNetZip represents the values with the - /// ModifiedTime, AccessedTime and CreationTime - /// properties on the ZipEntry. - /// - /// - /// - /// While any zip application or library, regardless of the platform it - /// runs on, could use any of the time formats allowed by the ZIP - /// specification, not all zip tools or libraries do support all these - /// formats. Storing the higher-precision times for each entry is - /// optional for zip files, and many tools and libraries don't use the - /// higher precision quantities at all. The old DOS time, represented by - /// , is guaranteed to be present, though it - /// sometimes unset. - /// - /// - /// - /// Ok, getting back to the question about how the LastModified - /// property relates to this ModifiedTime - /// property... LastModified is always set, while - /// ModifiedTime is not. (The other times stored in the NTFS - /// times extension, CreationTime and AccessedTime also - /// may not be set on an entry that is read from an existing zip file.) - /// When reading a zip file, then LastModified takes the DOS time - /// that is stored with the file. If the DOS time has been stored as zero - /// in the zipfile, then this library will use DateTime.Now for the - /// LastModified value. If the ZIP file was created by an evolved - /// tool, then there will also be higher precision NTFS or Unix times in - /// the zip file. In that case, this library will read those times, and - /// set LastModified and ModifiedTime to the same value, the - /// one corresponding to the last write time of the file. If there are no - /// higher precision times stored for the entry, then ModifiedTime - /// remains unset (likewise AccessedTime and CreationTime), - /// and LastModified keeps its DOS time. - /// - /// - /// - /// When creating zip files with this library, by default the extended time - /// properties (ModifiedTime, AccessedTime, and - /// CreationTime) are set on the ZipEntry instance, and these data are - /// stored in the zip archive for each entry, in NTFS format. If you add an - /// entry from an actual filesystem file, then the entry gets the actual file - /// times for that file, to NTFS-level precision. If you add an entry from a - /// stream, or a string, then the times get the value DateTime.Now. In - /// this case LastModified and ModifiedTime will be identical, - /// to 2 seconds of precision. You can explicitly set the - /// CreationTime, AccessedTime, and ModifiedTime of an - /// entry using the property setters. If you want to set all of those - /// quantities, it's more efficient to use the method. Those - /// changes are not made permanent in the zip file until you call or one of its cousins. - /// - /// - /// - /// When creating a zip file, you can override the default behavior of - /// this library for formatting times in the zip file, disabling the - /// embedding of file times in NTFS format or enabling the storage of file - /// times in Unix format, or both.

The managed code logic instantiates a ZipFile, and -// then extracts each entry. The embedded resources include the zip archive content, -// as well as the Zip library itself. The latter is required so that self-extracting -// can work on any machine, whether or not it has the DotNetZip library installed on -// it. -// -// What we need to do is create the animal I just described, within a method on the -// ZipFile class. This source module provides that capability. The method is -// SaveSelfExtractor(). -// -// The way the method works: it uses the programmatic interface to the csc.exe -// compiler, Microsoft.CSharp.CSharpCodeProvider, to compile "boilerplate" -// extraction logic into a new assembly. As part of that compile, we embed within -// that assembly the zip archive itself, as well as the Zip library. -// -// Therefore we need to first save to a temporary zip file, then produce the exe. -// -// There are a few twists. -// -// The Visual Studio Project structure is a little weird. There are code files -// that ARE NOT compiled during a normal build of the VS Solution. They are -// marked as embedded resources. These are the various "boilerplate" modules that -// are used in the self-extractor. These modules are: WinFormsSelfExtractorStub.cs -// WinFormsSelfExtractorStub.Designer.cs CommandLineSelfExtractorStub.cs -// PasswordDialog.cs PasswordDialog.Designer.cs -// -// At design time, if you want to modify the way the GUI looks, you have to -// mark those modules to have a "compile" build action. Then tweak em, test, -// etc. Then again mark them as "Embedded resource". -// -// ------------------------------------------------------------------ - -using System; -using System.Reflection; -using System.IO; -using System.Collections.Generic; - - -namespace Ionic.Zip -{ -#if !NO_SFX - /// - /// An enum that provides the different self-extractor flavors - /// - public enum SelfExtractorFlavor - { - /// - /// A self-extracting zip archive that runs from the console or - /// command line. - /// - ConsoleApplication = 0, - - /// - /// A self-extracting zip archive that presents a graphical user - /// interface when it is executed. - /// - WinFormsApplication, - } - - /// - /// The options for generating a self-extracting archive. - /// - public class SelfExtractorSaveOptions - { - /// - /// The type of SFX to create. - /// - public SelfExtractorFlavor Flavor - { - get; - set; - } - - /// - /// The command to run after extraction. - /// - /// - /// - /// - /// This is optional.

There is one - /// exception to this recommendation, described later. - /// - /// - /// - /// When using an arbitrary, non-UTF8 code page for encoding, there is no - /// standard way for the creator application - whether DotNetZip, WinZip, - /// WinRar, or something else - to formally specify in the zip file which - /// codepage has been used for the entries. As a result, readers of zip files - /// are not able to inspect the zip file and determine the codepage that was - /// used for the entries contained within it. It is left to the application - /// or user to determine the necessary codepage when reading zip files encoded - /// this way. In other words, if you explicitly specify the codepage when you - /// create the zipfile, you must explicitly specify the same codepage when - /// reading the zipfile. - /// - /// - /// - /// The way you specify the code page to use when reading a zip file varies - /// depending on the tool or library you use to read the zip. In DotNetZip, - /// you use a ZipFile.Read() method that accepts an encoding parameter. It - /// isn't possible with Windows Explorer, as far as I know, to specify an - /// explicit codepage to use when reading a zip. If you use an incorrect - /// codepage when reading a zipfile, you will get entries with filenames that - /// are incorrect, and the incorrect filenames may even contain characters - /// that are not legal for use within filenames in Windows. Extracting entries - /// with illegal characters in the filenames will lead to exceptions. It's too - /// bad, but this is just the way things are with code pages in zip - /// files. Caveat Emptor. - /// - /// - /// - /// Example: Suppose you create a zipfile that contains entries with - /// filenames that have Danish characters. If you use equal to "iso-8859-1" (cp 28591), - /// the filenames will be correctly encoded in the zip. But, to read that - /// zipfile correctly, you have to specify the same codepage at the time you - /// read it. If try to read that zip file with Windows Explorer or another - /// application that is not flexible with respect to the codepage used to - /// decode filenames in zipfiles, you will get a filename like "Inf?txt". - /// - /// - /// - /// When using DotNetZip to read a zip archive, and the zip archive uses an - /// arbitrary code page, you must specify the encoding to use before or when - /// the Zipfile is READ.

One strategy for - /// specifying the code page for a given zip file is to describe the code page - /// in a human-readable form in the Zip comment.
