  • Ipad: Zip Large files
    I use Documents over the files app for most things. I haven't had a problem zipping. But I have never tried to zip files not already on my iPad. Could work for you though. Source: over 3 years ago
  • Is there a way to selectively mass delete photos from an iPhone?

  • I don’t understand how sending files from a USB/PC to my iPhone can be so complicated. How do I just send these clips to my phone? Info in comments
    Another option is to download an app onto your iPhone that allows for file transfers using iTunes, like Documents by Readdle. Then you can use the instructions from Apple about File Sharing, but you will see Documents in the list instead... Source: almost 4 years ago
