X-plore by Lonely Cat Games is a file manager application for your Android, Windows or Symbian phone. I tested it on an Android phone (Samsung Galaxy S3, latest OS build from Verizon). The app is completely free with no timed trial or limited functionality. If you find the app useful, you can donate to the developers.
X-plore gives you the ability to connect to your:
- microSD card
- Cloud storage (Dropbox, Google drive, Skydrive, etc)
- Picasa image albums
- Supports rar and zip files
- FTP, FTPS, LAN servers
You can copy, move, delete, rename, zip, view (images, audio, video and text), and view SQLite database files (read-only).
What does this all mean? Well in my case, my last phone was an iPhone 4; to load music onto that phone, I would copy the music to my computer, load it into iTunes, and then connect the phone to my computer to sync the music. With my Samsung Galaxy S3 and X-plore, the same operation is done as follows: open X-plore, connect one pane to my NAS (network attached storage), in the other pane connect to my music folder on my external microSD card, and copy the music directly to my phone! Done!
