HOW IT WORKS
Evidence before assumptions.

Checks tailored to each format report dimensions, pages, tracks, encoding, metadata, table shape, or archive details.
- 3Explain the next step
Compatible converters include a clear purpose and a quality or feature warning before you continue.
GOOD TO KNOW
Clear limits,
useful answers.
File Doctor is precise about what it can and cannot establish.
Does File Doctor scan for malware?
No. File Doctor examines file signatures, structure, selected metadata, and processing limits. It never runs an uploaded file, but it cannot certify that a file is harmless or authentic.
How long does Fylovo keep an inspected file?
The uploaded source is removed immediately after inspection. The small text report remains available through its private random link for no longer than one hour.
Can File Doctor identify a file with the wrong extension?
Yes. Detection is based on file signatures and internal structure rather than trusting the filename. The report clearly explains when the extension and detected content disagree.
How does File Doctor check an archive?
It reads the directory without extracting entries, then evaluates entry count, declared expanded size, compression ratio, unsafe paths, links, encryption, nested archives, and executable-like filenames.
