What is a .S19 file?
S19 is a Motorola S-record firmware file with 16-bit addresses.
- Did you know
- The digits name the record types the file uses, not its address width: .s19 pairs S1 data records with an S9 terminator, .s28 uses S2 and S8, and .s37 uses S3 and S7.
- Motorola devised S-records in the mid-1970s for the 6800 processor, encoding binary firmware as printable ASCII hex.
- An S19 file uses a 16-bit address field, so it can only span the first 64 KB of memory.
- What Analyser reads
- Inspect virtual-machine descriptors (VMware .vmx, VirtualBox .vbox, OVF/OVA), disc images (Nero .nrg, Alcohol .mds/.mdf, CloneCD), embedded firmware (Intel HEX, Motorola S-record, UF2, ELF/AXF, Device Tree Blobs, U-Boot uImage), partition tables (MBR/GPT with GUIDs), Linux filesystem superblocks (ext2/3/4, SquashFS, cramfs, romfs) and Windows imaging (WIM/ESD) - reading headers directly, no upload. The two generic suffixes are handled on their bytes rather than their name: a .bin opens in the raw-binary inspector (magic-byte guess, entropy profile, hex and ASCII dump) and names itself when the signature proves a raw BIN/CUE disc image or a Mega Drive cartridge dump, while a .out is read as either the ELF executable a compiler left behind or the plain-text log a batch job dumped. Either one is re-routed automatically when its bytes turn out to be a real format.
- Depth of analysis
- .S19 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .S19 file
- Drag a .S19 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
