Dear all..
i have many file with name by modified julian date..i have used matlab progrrming JD2CAL (Converts Julian date to calendar date using algorithm).. It is succesfull but the problem is when day in January , November and December..For example 1112007.txt represent for 11/1/2007 but problem for file date 1/11/2007 ..it also will rename the file with 1112007.txt..So, the data for this two date will mix together..how i can solve it?

Either use 2 digits for the day and the month, or add a separator.
sprintf('%.2d%.2d%.4d', 1, 1, 2007)
sprintf('%d_%d_%d', 1, 1, 2007)
I'd prefer this, because the alphabetical order equals the temporal order:
sprintf('%.4d%.2d%.2d', year, month, day)

file=datestr(datenum(date),'dd/mm/yyyy')
file([3,6])=[]
file=[file '.txt']

joo tan, you'll note that you did not give any examples of your initial, original filenames/strings, or the desired, ending filenames. You just gave one filename so it's not clear what you are starting with. We don't know if you have actual filenames that you need to convert, or some strings that you want to build up with the current date that you will then use to create the file, or something else. If you clarified your situation, you'd eliminate all the confusion and guessing that you're causing.

The jd2cal function returns [yr,mn,dy]. It is not the source of the ambiguity.
