How to delete TranscoderTimedSnapshot png files

I am using TranscoderTimedSnapshot lib.

Every minute, the screenshot is saved in the content folder.
I want to delete my previous screenshots
"https://www.wowza.com/docs/how-to-take-timed-thumbnail-snapshots-of-a-wowza-transcoder-stream-moduletranscodertimedsnapshot"
There is no delete method for the document. I need help.

Hello @seungyeon kim,

Because these files are created and are now part of the OS file system, they would need to be deleted manually or through an OS level script.
