Yesterday I was trying to open a .zip file on my phone that was around 510MB and when I click on that firstly it was opening then I got error by MS OFFICE that "there is not enough space to open this file" and now I have 510.22MB temporary files in my phone and I tried several times to delete them but it didn't make any deferance. And I also tried some cleaning applications and they are also not working. Please tell me what to do in my Lumia 1320 8.1 phone. . . .
