Renaming file using batch script

[sternkanz]

Hi, I want to make a batch script which takes a file name which comes in this format:

MonthDayYearHoursMinutesSecondsAM/PM.pdf

and renames it to

YearMonthDayHoursMinutesSecondsAM/PM.pdf

For example:

09302008092212AM.pdf -> 20080930092212AM.pdf

I am hoping I can use the for command to do this somehow. Maybe someone can tell me if I can use "2 characters" as a delimeter, that way I could split it into 09 30 20 08 09 22 12 AM .p df and rearrange.

Any help would be highly appreciated,

Thanks

Here's an example of variable expansion, (see SET /?), which should help you out!

@Echo off&Setlocal
Set "_=09302008092212AM.pdf"
Set "_=%_:~4,4%%_:~0,4%%_:~8%"
Echo:%_%&Pause
