Check a TAR file
Inspect a .tar archive for header checksum problems, malformed member sizes, truncated data, block-padding issues, unsafe extraction paths, and archive-end warnings — directly in your browser.

TAR archive won’t extract or looks incomplete?
Start with the archive structure itself. ARADURU checks TAR member headers and block boundaries before you assume the extraction application or archived files are the problem.
Structure checks across the TAR archive
ARADURU walks TAR members on 512-byte boundaries and verifies file-side evidence without extracting member contents to the server.
Header checksums
Compare each stored TAR header checksum with the bytes in its 512-byte member header.
Member sizes
Parse standard TAR size fields and stop safely when a member boundary cannot be determined without guessing.
Data boundaries
Confirm that each declared member payload remains inside the selected TAR archive.
Block padding
Check the 512-byte padding needed before the next TAR member header can begin.
Archive-end marker
Review the zero-block end marker and distinguish a missing or incomplete marker from a direct member-corruption error.
Extraction paths
Flag member paths that may escape a normal destination directory if an extractor does not sanitize them.
A healthy TAR archive does not prove every member file is healthy.
ARADURU checks the TAR container, member headers, checksums, sizes, block boundaries, and extraction-path evidence. Each archived file can still require its own format, syntax, security, or application-specific check after extraction.
- Keep the original. Extract or repair a copy when the archive matters.
- Use a trusted extractor. Prefer software that sanitizes member paths before writing files.
- Check extracted files separately. A healthy TAR wrapper does not validate each archived file.
- Use Upload Check. Compare the .tar file with a destination’s size, type, and filename rules.
