This uploader is designed for private file transfer. In its default private policy, arbitrary file formats can be accepted within configured size and operational limits. Active or executable content is never run by the server, and potentially active content is served as a download.
Accepted files still pass filename, size, and security checks. A known file signature that conflicts with its filename may be rejected. An unrecognized signature is treated as unknown rather than as malware.
Preview support is narrower than upload support. Browsers commonly preview recognized images, audio, video, and PDF files. Other allowed formats are provided as downloads. Browser support and actual file validity determine whether media playback works.
Files may be blocked by the active validation policy or rejected after a verified malware detection. If the scanner is unavailable, unverified files remain private and no public link is issued.
