I have folder where weekly backup are taken...
week1_bkup_02102011
week2_bkup_09102011
week3_bkup_16102011
.
.
everyweek a backup is created
I want to delete all folder except latest one
for example in above a week4_bkup_23102011 is added then it should remove all other three. only latest one should be present.
