FLP (.flp)
.flp file signature | application/octet-stream
FLP is a project file format created and maintained by Image-Line for FL Studio. It stores arrangement data, patterns, automation, mixer settings, and plugin references for composing, editing, and reopening music production sessions. As a project container rather than an executable format, it is generally safe, though loading files from untrusted sources may trigger plugin-related compatibility issues or rely on external assets that are not embedded in the project.

Frequently Asked Questions
What is a .flp file?
A .flp file is identified by the magic bytes 46 4C 68 64 at byte offset 0. FLP is a project file format created and maintained by Image-Line for FL Studio. It stores arrangement data, patterns, automation, mixer settings, and plugin references for composing, editing, and reopening music production sessions. As a project container rather than an executable format, it is generally safe, though loading files from untrusted sources may trigger plugin-related compatibility issues or rely on external assets that are not embedded in the project.
What are the magic bytes for .flp files?
The magic bytes for FLP files are 46 4C 68 64 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .flp file?
To validate a .flp file, read the first bytes of the file and compare them against the known magic bytes (46 4C 68 64) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .flp files?
There is no officially registered MIME type for .flp files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .flp files?
FLP (.flp) 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.
