VDR (.vdr)
.vdr file signature | application/octet-stream
VDR is a RIFF-based legacy video file format created and maintained by its original proprietary software vendor, with support now largely limited to older applications. It is used to store video data and related metadata for playback, editing, and transfer within compatible media tools. As an older format, VDR may be unsupported in modern software, but it is generally considered safe to open when obtained from trusted sources.

Frequently Asked Questions
What is a .vdr file?
A .vdr file is identified by the magic bytes 52 49 46 46 56 44 52 4D at byte offset 0. VDR is a RIFF-based legacy video file format created and maintained by its original proprietary software vendor, with support now largely limited to older applications. It is used to store video data and related metadata for playback, editing, and transfer within compatible media tools. As an older format, VDR may be unsupported in modern software, but it is generally considered safe to open when obtained from trusted sources.
What are the magic bytes for .vdr files?
The magic bytes for VDR files are 52 49 46 46 56 44 52 4D at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .vdr file?
To validate a .vdr file, read the first bytes of the file and compare them against the known magic bytes (52 49 46 46 56 44 52 4D) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .vdr files?
There is no officially registered MIME type for .vdr files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .vdr files?
VDR (.vdr) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
