Hello Guys
I Made a HDA For My Pipeline
I Added a Toggle Parameter Into My HDA and I Called "Remove From Disk"
So , I Wanna Removed Cache Files Like : "bgeo bgeo.sc vdb ,etc..." When Toggle Button Has Been Ticked , With Python Code
Thanks Your Help !

You can try to utilize TOP nodes to do the job. The reason for this, if you rendering/saving files in TOPs, you can use the @pdg_output attribute to remove those files by TOP File remove node and don't parse paths, filenames or frames manually.
I'm not very confident with PDG at the moment to give you a complete example, but you can take a look at the last hip file at the topic: https://www.sidefx.com/forum/topic/62404/?page=1#post-282398 [www.sidefx.com]
