Real-Life Use Cases for DAT Files and FileViewPro > 자유게시판

A .DAT file has no universal definition because it’s merely a label that programs use for storing data, meaning its contents depend entirely on the creator; sometimes it’s readable text like logs or configuration files, other times it’s binary that only its parent app understands, and some DATs are actually video (like VCD files or DVR exports), so identifying it requires checking where it came from, how large it is, whether Notepad shows readable content, and possibly examining magic bytes to see if it’s really a ZIP, MP4, or PDF underneath.

A .DAT file acts as a catch-all storage file, and the extension alone doesn’t reveal its true format; it usually ends up being either plain text—readable in Notepad as settings, logs, lists, JSON/XML, or CSV-style rows—or binary, which appears as gibberish because it’s structured for software, not people, and in that case only the original program or a dedicated extractor can interpret it, since DAT isn’t a standardized type like PDF or JPG and two DAT files can contain completely different kinds of content.

This ultimately means there’s no catch-all "DAT opener": you determine how to open it by checking its context, trying a text editor, and using the proper application or extractor when it’s binary, sometimes uncovering that it’s actually a standard file type like MPEG video; binary DATs are prevalent because they store structured, often performance-critical data, which looks like gibberish in Notepad, and they populate folders for games, applications, and devices like DVRs, so practical opening methods include launching them within the original software, using a specific extractor for that ecosystem, or reading their signature to find out whether they’re secretly a known format.

.DAT files often fall into recognizable "themes": disc-video DATs from VCD/SVCD that function as MPEG files, email-related DATs such as winmail.dat that package attachments in TNEF, CCTV/DVR export DATs that require proprietary players, and software/game data bundles that contain internal resources; because "DAT" isn’t a fixed format, the best method is to categorize the file by its source, filename, folder companions, and whether it resembles text, video, or structured binary.

A practical way to identify a DAT file is to use a simple workflow: consider its source (VCD DATs are often MPEG, winmail.dat is email packaging, CCTV DATs need vendor tools), test it in Notepad to see if it’s readable or binary, check the size to guess whether it’s lightweight settings or heavyweight media, examine folder companions for contextual clues, and if necessary inspect its header for standard file signatures so you know the proper tool to open it.

When .DAT is used for video storage, it’s typically just a generic label on top of an actual stream, most famously on VCD/SVCD discs where `AVSEQxx.DAT` often hides an MPEG-1/2 file that VLC can open or that works after being renamed `.mpg`; CCTV/DVR `.dat` files, however, tend to be proprietary and won’t play in standard players, so they require the system’s own playback/conversion tool, and the quickest identification path is to test VLC, check for VCD-style folders, and fall back to DVR software if VLC fails.
