Not a question but a scary tale. Running View NX 2.3.1 32 bit, I experienced an odd behaviour. I use to download my images in files, files are automatically named with date and a brief title. I opened the last file but one, and to my surprise I found some pics that should have been in the latest file... I then checked the latest file and found that they were duplicated in both files. I didn`t do so. I checked the serial numbers of the duplicated photos, and they were different. I then copied and pasted the duplicated photos in a new file to keep them just in case. When I opened the file for checking, more photos, that were not selected from the last but one file, were duplicated and pasted, too. After checking that the non-selected, original ones were in the right place too, I selected and deleted them. Again, to my surprise, all the photos , selected and not, from the just created new file were deleted. I got scared. After that, looks like all the photos returned to their original files. Better if you have a good backup system.
