About FileDummy
FileDummy (filedummy.ndlong.site) is a specialized developer tooling platform built to provide software engineers, QA testers, security auditors, and system administrators worldwide with instant, clean, and standardized dummy files for upload and performance testing.
Our Mission & Purpose
Testing file upload limits, multi-part form handlers, CDN pipelines, and media transcoding services is a daily necessity for software teams. Yet finding reliable test files usually means browsing suspicious download portals filled with pop-ups, trackers, and potential malware risks.
FileDummy was engineered to eliminate this friction. Every file available on our platform is generated programmatically with valid format headers, zero malicious payload, and strict byte-exact precision.
Valid File Structures
All files are synthesized in isolated build pipelines using standard dummy content and authentic magic bytes. They contain no macros, executables, external scripts, or tracking beacons.
Exact Byte Precision
Every sample file is engineered to strict binary boundary standards (e.g., a 10MB test file contains exactly 10,485,760 bytes), providing dependable boundary testing for form quotas and backend file size validators.
CI/CD & CLI Ready
Every file page provides ready-to-run terminal snippets for cURL, Wget, Python, and Node.js so automated CI/CD build scripts can pull test fixtures reliably without manual downloads.
High-Throughput Storage
All sample assets are served from low-latency edge caching networks, ensuring rapid transfer speeds for load testing and benchmark pipelines.
