Paessler PRTG Monitoring System database file (.db)
.db file signature | application/octet-stream
The .db format is a database file used by Paessler PRTG Monitoring System, maintained by Paessler AG. It stores monitoring data, configuration records, and historical sensor information for PRTG installations, supporting network supervision and reporting tasks. These files are generally safe and intended for internal application use; however, they should be opened or modified only with compatible Paessler software to avoid data corruption.

It stores monitoring data, configuration records, and historical sensor information for PRTG installations, supporting network supervision and reporting tasks. These files are generally safe and intended for internal application use; however, they should be opened or modified only with compatible Paessler software to avoid data corruption.
What are the magic bytes for .db files?
The magic bytes for Paessler PRTG Monitoring System database file files are 53 51 4C 69 74 65 20 66 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .db file?
To validate a .db file, read the first bytes of the file and compare them against the known magic bytes (53 51 4C 69 74 65 20 66) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .db files?
There is no officially registered MIME type for .db files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .db files?
Paessler PRTG Monitoring System database file (.db) 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.
