i am having a folder Dir_1.
it has many files like
file1
DOC ( this is a Directory)
file2
after i execute my test the folder contents change like
file1
file2
<file3
DOC
DIR_2
i had written a procedure which does folowing thing
it accepts a array as arguments which has all files names in current working Directory. all files before execution of script are in this array
inside the procedure again i define a array which contain all the files in current working Directory. this will include all files generated by test script.now i want to delete those files which were in old array and not in new array.
one way of doing is to compare each file of both arrays using for loop but this is highly ineffcient. can you tell me to do same in much efficient manner
