Что такое формат файла AQQ?
.aqq is a proprietary data file created by the AQQ instant messenger (Komunikator AQQ), a Windows-based multi-protocol IM client developed in Poland by WapSter and later Creative Team S.A. The application appeared around 2004 and supported popular Polish and international messaging protocols, including Gadu-Gadu, Tlen, and Jabber/XMPP.
The .aqq extension identifies internal application data files generated and read exclusively by the AQQ client. These files are stored in binary format and typically occupy only a few kilobytes. Their exact on-disk structure is proprietary and has never been publicly documented, so the files cannot be meaningfully opened outside of AQQ itself.
No public MIME type is registered for .aqq; operating systems default to application/octet-stream when handling these files. There is also no known file signature (magic bytes) that would allow third-party tools to identify them reliably.
AQQ was actively developed through the early-to-mid 2010s. After development ceased, the application and its file formats became effectively legacy artifacts. No open-source or cross-platform alternative reads .aqq files, and no documented migration path exists for the data they contain. Windows is the only operating system on which the format was ever used.
Безопасность и защита
РИСК: MEDIUMThe file itself is application data and is not known to be executable, so the .aqq is not an obvious threat. The real cautions are around the application: AQQ is an old, no-longer-actively- developed Windows messenger, so downloading installers from unofficial 'download portals' risks bundled adware/PUPs - only get it from the official site (aqq.eu) if you must. As with any old IM client, an unmaintained app may carry unpatched vulnerabilities; weigh whether recovering the file's data is worth running legacy software.
