## Recognized File Types

Supply Chain recognizes but does not scan the following common file types.

| Category | File Types |
|  --- | --- |
| Documentation | .md (READMEs, release notes) |
| Code Files | .py (scripts), .js (optional), .sh (shell scripts) |
| Config / Metadata | .json, .yaml, .yml, .ini, .cfg |
| Data Files | .txt, .csv, .tsv |
| Git Config Files | .gitignore, .gitattrib |
| TAR | .tar |


## Unsupported Types

If AI Supply Chain Security does not support, or is unable to recognize, the type of an input file, it will emit a scan result with empty detections and results.type key set to "unknown".
