Here is a little contribution to the GXR community.
In order not to mix the GXR image files with my GRD's, I managed to set the GXR file number to begin with 2000000, eg R2000000.jpg.
This is how I did it :
1. Insert a SD card into the GXR and format it (yes, it will clear all data).
This will reset the folder number to 100 (ie. 100RICOH) but GXR still remembers the last sequence so the next picture will be named R1004456.jpg for example.
2. To force the sequence to 200000, create a new folder 199RICOH, copy a GXR picture file to it and rename it to R1999999.jpg
3. Re-insert the SD card into the camera and take another picture. This time, it will be named R2000000.jpg and stored in 200RICOH folder
