S9+ memory full problem

[Elkski]

I cant take  pictures.   Memory  is full 64 gb.  I've been offloading  pictures every couple of days to s thumb drive.   But after offloading 1.6 gb and then deleting the pictures in my gallery phone is still full.   I swear I saw a empty trash bin button last week and I thought  that opened up space after deleting pictures.   I cant find where to  empty the trash?  I'm thinking the pictures are deleted but still  occupying space.  It seemed to work that way  last week. I clean memory and storage  in  device care.  I'm wondering  if I have a virus or what to do.

Just did a main cache clear in diagnostic  mode but still no room?.  I dont get memory full error but I start to take a video and it shows I can only take 13 seconds not the 60+ minutes I should have.

I read where someone else had issues with this other location taking up all the memory.

I fixed it.  Went into settings/

Apps then looked at gallery  and opened  its setting gear next to it.  Then unchecked the save deleted files for 30 days.
