Not enough space to free up space

I'm trying to delete some files from my iPhone's **Files** app, and I am getting a pop-up message: **"Filename" couldn't be moved to ".Trash" because there isn't enough space.** The volume "User" is out of space. OK 📱🤦 = The first thing I try when running out of space is *try to free up space in files.app* I presume this can't be done by first moving files to .Trash and that a **Delete Immediately** option is needed. I'd like an automation Workflow that will delete files immediately. **Note:** This is not an emergency. I will eventually be able to solve this by moving photos onto my Mac, but while I'm not near my computer or don't have time for that, a quick-and-easy fix would be nice to have. And there are some media files on my iPhone that also exist elsewhere, so I am fine with deleting this redundant data. I am not asking about what to do about an iPhone that is inoperable or won't boot. There is already [a Q&A for that](https://apple.stackexchange.com/a/465593/) . I am specifically asking if there is a way to remove data from Files that doesn't require a lot of memory overhead. My phone is still working and can restart. **What are my options?**
