I have a webcam, making movies and the movie is stored in this way:
20110119071051 (year, month, day, hour, minute, second and I cannot change the filename)
I would like to rename the file and split it into year, month, day, hour, minute, second with underscores, so it looks like 2011_01_19_07_10_51
How do I do this ?
Thanks in advance,
