Re: I am unable to unzip software that I download
If you are not already using this method, try using the method below from Apple Support's article:
How to open ZIP files on your iPhone, iPad, or iPod touch
Says:
"How to open a ZIP file on your iPad
- Open the Files app, then find the ZIP file or archive you want to uncompress.
- Tap the ZIP file or archive.
- A folder is created containing the files. To change its name, touch and hold on the folder, then tap Rename".
