Can't Open Your .DVS File? Try These Steps

DVS files can originate from several different programs and aren't universally openable.

1. Identify the Source: If it came from a security team, it's likely a DVTel Video Surveillance file. If retrieved from an email archive, it may be a Veritas Enterprise Vault file.
2. Check the Header: Open the file in a hex editor to inspect its first bytes:
   • Video headers (like RIFF) suggest a DVTel media file.
   • Readable XML or text often points to an Enterprise Vault archive or Developer Studio workspace.
3. Use the Original Software: You usually need the original program, such as DVTel DVS Player, Veritas Enterprise Vault, or Microsoft Visual Studio. If uncertain, ask the sender.
4. Use this Webpage: Drag and drop your .DVS file onto this page to automatically detect its format, extract readable metadata, and preview its contents when possible.

DVS file format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below is our analysis of the DVS files:

The DVS file extension is rarely used and covers different formats for different programs. The two most popular formats are as follows:

• 35% of all DVS files start with the bytes ED 03 00 00 00 00 01 00 crucial for this file format. If you open these files in a text editor, you will see only illegible characters. The files are on average 70 MB in size and range from 70 MB to 240 MB. It is a modern file type.
• 30% of all DVS files are based on the zip format, so several files are compressed and saved in one DVS file. DVS files contain from 7 to 12 compressed files. File names inside are BalanceInfo.xml, DaVinci.sqlite, History.sqlite, SystemMessages.xml, Trace.log, TypeData.sqlite and system-trace.log. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. Most of these files are 680 KB to 21 MB in size. Several words can almost always be found in the files, e.g. system-trace.log. An example of a file name is SupportFile_20180601.dvs. Such files are related to support.

The remaining 35% of all DVS files are files with no common format, often, for example, DeepVision sonar format and Honeywell. Just click the "Choose your .dvs file to analyze" button on this page to find out what your DVS file is.
