R (.rdata)
.rdata file signature | application/octet-stream
R Data files are workspace and object serialization files used by the R programming language, developed and maintained by the R Core Team. They are used to store datasets, model objects, and session state for later analysis or sharing, and are commonly read by R and compatible tools. The format is generally safe, although loading untrusted files can execute code during deserialization in some cases; it is a long-standing R format rather than a legacy one.

Frequently Asked Questions
What is a .rdata file?
A .rdata file is a R file. R Data files are workspace and object serialization files used by the R programming language, developed and maintained by the R Core Team. They are used to store datasets, model objects, and session state for later analysis or sharing, and are commonly read by R and compatible tools. The format is generally safe, although loading untrusted files can execute code during deserialization in some cases; it is a long-standing R format rather than a legacy one.
What are the magic bytes for .rdata files?
The magic bytes for R files are 52 44 58 32 0A at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .rdata file?
To validate a .rdata file, read the first bytes of the file and compare them against the known magic bytes (52 44 58 32 0A) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .rdata files?
There is no officially registered MIME type for .rdata files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .rdata files?
R (.rdata) 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.
