+## H3 Motion Context Clip Purge
+![H3MotionContextClipPurge.png](https://raw.githubusercontent.com/noembryo/ComfyUI-noEmbryo/refs/heads/master/stuff/H3MotionContextClipPurge.png)
+Deletes the numbered `h3_motion_context_av_v1` clip archive files at the root of a folder (default: `h3_context`)  
+Only files matching the pattern are removed; sub-folders and everything inside them are left untouched.
+
+- **Controls**
+  - **mode**: Purge (Enabled): delete the matching files.  
+    Preview (dry run, Disabled): delete nothing; the report just lists the files that would be deleted.
+  - **folder** is the folder whose root-level clip archives will be deleted.  
+    Absolute paths and paths relative to ComfyUI/output are accepted.
+  - **pattern** is the filename glob. Only root-level FILES matching this pattern are deleted.  
+    Sub-folders are never touched.
+- **Outputs**
+  - **report**: Shows the actions of the node.
