646:(Explorer) schon seit fünfzehn Jahren so (Windows 95), und selbst unter DOS läßt sich sowas problemlos für die Kommandozeile einrichten, bzw. war in Dateimanagern wie dem Norton Commander schon vor bald zwanzig Jahren integriert. Es ist eine wirklich sehr schlechte Idee, ausführbare Dateien (wie .EXE-Dateien) über das Netz verteilen zu wollen - im Grunde halte ich das für unverantwortlich, gerade wenn man auch unbedarfte "Nur-Anwender" in der Zielgruppe hat. Ausführbare Dateien stellen ein erhebliches Sicherheitsrisiko dar, denn sie können Viren enthalten (und tun dies auch oft). Deshalb blockieren viele Virenscanner und Firewalls sowas, und die Anwender, die sich an die Instruktionen auf Sonys Webseite halten (gerade, weil sie nichts falsch machen möchten), werden Schwierigkeiten haben, die Datei überhaupt herunterladen zu können. Die Leute, die es dennoch schaffen, werden u.U. mit dem nächsten Problem konfrontiert, nämlich der Tatsache, daß der spezielle Selbstentpacker, der in der .EXE-Datei integriert ist, nur unter bestimmten Versionen von Windows funktioniert. Manche Windows x64-Versionen, manche Windows Starter-Versionen und manche älteren Windows-Versionen werden nicht unterstützt. Das muß nicht so sein, man müßte einfach nur einen Selbstentpacker verwenden, der mit allen Windows-Versionen kompatibel ist.

365:. Decompression utilities must be able to handle both the file format and the algorithm used when expanding self-extracting or standard archives. Depending on the options used to create a self-extracting archive, the executable code placed at the beginning may vary. When comparing a LZMA 7z archive to a LZMA2 7z archive, for example, the decompression routines will differ.

349:, and others. Many programs can handle multiple types of archives, whereas others can create, extract, or modify only one type. Additionally, there is a distinction between the file format and the compression algorithm. A single file format, such as 7z, can support multiple different compression algorithms, including

Some systems for distributing files do not accept executable files in order to prevent the transmission of malicious programs. These systems disallow self-extracting archive files unless they are cumbersomely renamed by the sender to, say, somefiles.exe, and later renamed back again by the recipient.

for security. It is important to note, however, that in many cases, the file and directory names are not included in the encryption and can be viewed by anyone without a key or password.

Unlike self-extracting archives, non-self-extracting archives only contain archived files and must be extracted with a program that is compatible with them. While some formats of self-extracting archives cannot be extracted under another operating system, non-self-extracting ones can usually still be

Self-extracting archives contain an executable file module, which is used to run uncompressed files from compressed files. The latter does not require an external program to decompress the contents of the self-extracting file and can run the operation itself. However, file archivers like WinRAR can

When sent as an email attachment or downloaded from the

For example, an archive may be called "somefiles.zip—it", which can be opened under any operating system by a suitable archive manager that supports both the file format and compression algorithm used. It may also be converted into somefiles.exe, which will self-extract under

Self-extracting archives will only run under the operating system family and platform with which they are compatible, making it more difficult to extract their contents under other systems. Examples of self-extracting archives, which can be run on multiple targets (such as

Self-extracting archives can also be used by users without the necessary programs for extracting their contents, as long as they run a compatible operating system. A self-extracting archive may still be more convenient for users who do have archive management

still treat a self-extracting file as if it were any other type of compressed file. By using a file archiver, users can view or decompress self-extracting files they received without running executable code (for example, if they are concerned about viruses).

Self-extracting files are used to share compressed files with a party that may not have the software needed to decompress a regular archive. Users can also use self-extracting archives to distribute their own software. For example, the
