+
+Tas/Berry/Other features used:
+* Tas filesystem
+
+Any and all contributions welcome without specific consultation.  I don't consider this module to be production quality.
+
+## Files in this folder relate to the use of folders from Berry in Tasmota.
+
+
+### Requirements
+
+Latest development version
+
+### Files:
+
+#### [zap.be](./zap.be)
+This provides a zap(folder) function which will delete a folder and all content
+
+* Stability: Fairly stable, pending feedback.
+
+Usage:
+
+zap(folder)
+
+or 
+
+zap(folder, true) - to get more feedback in logs
+
+
+#### [testzap.be](./testzap.be)
+
+Creates some folders and files and then zap them.
+
+Example of usage of path.mkdir() and path.rmdir(), plus other file features.
+
+
+### Acknowledgements
+
+
+### Alternative approaches
+
+None.  There was no folder manipulation in TAS.
