I try rename filenames to "date time" by:
exiftool -d %Y%m%d_%H%M%%-c.%%e "-filename<CreateDate" -ext jpg *
When I run in folder with this files: DSC04921.JPG, DSC04926.JPG, DSC04927.JPG
I end up with this file: mHe, DSC04926.JPG, DSC04927.JPG
It seams problem with date?
if I run: exiftool -a -G1 -s -time:all -ext jpg *
CreateDate looks fine, it shows [ExifIFD] CrateDate: 2015:01:09 14:25:33
I use "Windows Executable: exiftool-10.12.zip (5.0 MB)" on Win7
