What is a .YAFFS2 file?
YAFFS2 is a flash filesystem image once common on Android devices.
- Did you know
- YAFFS2 was the filesystem on many early Android phones.
- YAFFS stands for Yet Another Flash File System and was written by Charles Manning for the firm Aleph One.
- YAFFS2 is a true log-structured filesystem, tagging each block with an increasing sequence number to suit modern write-once NAND flash.
- 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.
- Depth of analysis
- .YAFFS2 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 .YAFFS2 file
- Drag a .YAFFS2 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.
