I was in the middle of downloading a large video file from my phone when my phone's battery died. I was really frustrated because I had no way to continue the download on my laptop since the file was too large.
I decided to search for a file manager app that would allow me to continue the download on my phone. After doing some research, I found the File Manager app for Android phones. The app was easy to use and allowed me to continue the download on my phone. It also had cloud integration, so I was able to save the file to my Dropbox account.
