If I go into the apps section, then tap Files, then tap download, I find pictures that I have previously downloaded, which is fine, but I also find pdf documents downloaded from websites that I have visited,as well as an excel spreadsheet that I received in an email last summer. A sample of the pdf's include a price list and a menu from the venue where my daughter's wedding took place last year, a wanted poster for a murder suspect, and a fill-in form from the motor vehicle dept. for license renewal. I don't want this stuff in my phone and I had no idea it was there. I thought if I tap on the Downloads icon, it would show me a list of all the items that are downloaded to my phone and I could delete what I want from there. Apparently, I'm wrong. I can't figure out how to delete these items from the Files section. Please Help!
Part II - My daughter sent me an email with an excel attachment. I saved the attachment and I just found it in My Files section of Polaris Office. However, I cannot open the document, it says "Cannot support file format". I noticed a few other downloaded documents in Polaris Office that I cannot open. The same files I mentioned above that I wish to delete are found here as well. Thank you for any help you can offer me.
