It was very good but now you have to wait... – File Manager and Browser - Files App Review

Because they want you to buy the upgraded version and each time you open the app it pop and add saying to buy the upgraded version and sometimes if you don buy it you have to try different times to download. Maybe they going to withdraw the ability to download youtube videos adding the "ss"before "youtube" that will open the "save from net" site on the iOS devices like you do on Windows computer. I don't know if after the upgrade the app will be continue having such ability due to other frustrating experience on iOS restriction rules that doesn't allow to do many things. Otherwise if it continue to function the upgrade will be fine although this used to be a free app, and the "ss" trick I had to discover it my self and the developer of the app didn't say anything about.
