Safety Assessment

The File Merger is relatively safe when configured with strict directory access controls. Risks increase if allowed directories are too broad or if the output path is not carefully managed. Ensure proper input validation at the client level to mitigate potential malicious file content.

Directory access is limited to allowed paths.
No network access required.
Simple functionality reduces attack surface.
Uses standard file system operations.

Can overwrite existing files if the output path is not unique.
Potential for denial-of-service if very large files are merged.
Vulnerable to path traversal if allowed directories are not carefully configured.
No built-in input validation to prevent malicious file content.
