The .7z extension stands for . Unlike standard .zip files, .7z archives use the LZMA algorithm , which allows them to shrink large files into a much smaller footprint—often 30–50% better than standard ZIP compression. Common Uses for Files Like "TBDs"

Often used in firmware updates or software development builds.

The file appears to be a specific compressed archive typically used for distributing software updates, datasets, or specialized driver packages. While the exact contents depend on the context of where you found it, the suffix .7z confirms it is a high-compression archive created using 7-Zip .

Since Windows and macOS do not always support .7z files natively, you will need a third-party tool:
