The dat2 file extension is associated with XYplorer, a file manager, picture and multimedia viewer for Microsoft Windows developed by Lessau.
A dat2 file contains thumbnail cache data. It is an internal support file used by XYplorer to retain generated thumbnails and improve their display without recreating them each time.
dat2 files are intended for internal use by XYplorer and are not normally opened directly. Let XYplorer manage the file in its cache.
A dat2 file is a program cache rather than a user document, so it cannot be meaningfully converted to another format. XYplorer generates and manages the cached thumbnails itself.
