TAR Archive Creator

The tool writes an uncompressed USTAR archive locally. Folder selection keeps the relative paths supplied by the browser; dropping files does not traverse folders. Only regular files are written, including empty files; empty folders and symbolic links are not preserved. This implementation allows at most 500 files, 64 MiB per file and 128 MiB of input in total (1 MiB = 1,048,576 bytes). Each complete relative path is limited to 100 UTF-8 bytes; duplicate or unsafe paths abort the whole operation. These are implementation limits, not universal TAR limits. Generated files have mode 0644, owner/group IDs 0 and the generation time; original filesystem permissions and timestamps are not preserved. Headers, 512-byte padding and two ending blocks make the archive larger than the payload. No compression, encryption or File System Access API is used.
