USB Host is required if you want to copy files from an attatched external card reader or hard drive, but the app can be used to copy files around and extract preview images for files already on the device.

Olympus - ORF
Nikon - NEF
Panasonic - RW2

Panasonic - RAW Some newer cameras produce these files with an embedded jpg.
Minolta - MRW
DNG - partial support:
* Pentax generated DNGs, can extract embedded jpg.
* Leica M9 - No support, no embedded jpg to preview.
* Others - Unknown. Please try and let me know how you get on.
RAW - old Panasonic raw files, no embedded jpg to preview.
TIF - No plans to support.
If you have raw photo files that can't be processed, email me a couple and I will try to add support for them in the app.

Generate preview images sizes can now be 320 x 240 or 640 X 480.
Backup mode can be configured to do one of three things
1. Backup files
2. Backup files and extract previews.
3. Just Extract previews.
Note: The "Backup" button and description will change to match the selected mode.
Use the "Config" button to configure the source and destination folders for your backup.
"Backup" will then copy all the files from the source folder and sub folders to the destination folder.
These folders need to be under "/mnt", "/sdcard" "/removable" or start with "/usb" before you are allowed to perform a backup.
The status information will help you with your folder selection.
Enable the preview option to create a small jpeg preview of each photo during the copy.
The preview images can be viewed with your favourite image viewer and are added to the gallery.
Tap folders to enter them.

Press and hold for a context menu to select folder.
Keep pressing the back button to exit without making a selection.

Photos in the source folder are displayed on the main screen. The main photo can be changed by dragging the gallery control (looks a bit like a film strip) or by swiping left/right. Tap image to view full screen.
