Otg Disk Explorer Pro for Android
Firstly: if the free version is OTG Disk Explorer, keep the same naming syntax for the OTG Disk Explorer Pro too (not "Otg"). Secondly: it does not recognize/read/write my External SD Card. Thirdly: there are dedicated DCIM camera, Music, Video, Bluetooth and Downloads folders on the external SD cards too. Many users use them as implicite locations, since there's plenty of storage space for their stuffs there. Fourthly: you need to add some file systems support, such as NTFS, FAT32, FAT16, HFS and HFS+. Then it will be complete.
This app can not read and write NTFS formats.. these days high capacity external drives come with NTFS..You cant convert them to FAT32..
That's probably the app I use the most on my cell phone :) does what it says.

At first I loved this app. Clean and simple without bloat. With time I found 2 annoyances. First is the lack of exFAT support for larger disks. Second and more serious was how the cache seemed to grow gigantic when I copied large files like movies from the OTG drive. I have to remember to wipe cache or it will eat up the internal storage. Please fix this or include an option to clean it from the app.
