Default [Q] An app to mass-delete photos by date on android

My android phone warn me the storage is full. after checking by file manager app, I found the size of DCIM folder is 20G!! and there were some pictures located on the other app's folder..

Here is my action: Move all folders of photographic app into DCIM. Backed up all pictures under DCIM.

However I dont want to delete all photos by delete DCIM folder. instead. I would like to keep those photos taken within 6 months, and delete those more than 6 month.

I would like to know if any app can help me to to do this? ex: search files( or only pictures) which date more than 6-month on target folder(s) -> select all -> delete

ps: I know that I could use adb shell busybox find ... -exec rm .. , but if there is an app could do this , that would be easier
