hi,
as i already discussed in my last thread that my exe is not working for large number of files but it is doing really well with fewer files.
today i took a screenshot and got the following error...
here is my code..i am even trying to put delay in it..kindly suggest ways to add delay fuction beacuse it is giving an error evry time i use it and please look into it if anyother solution or change is required...

oops i forgot to write the error i am getting everytime i execute my exe...
could nt find C:\Documents and Settings\admin\Desktop\y\filelist.txt

Looks and sounds like your program is expecting filelist.txt to exist in C:\Documents and Settings\admin\Desktop\y\
, and if its not there, is giving you that message.. doesnt appear to be any error handling if 'ERASE' does not work.

but it is working fine with lesser number of files..
i really need something that makes it work on a larger data

thankyou for the remark..
i will try it too..
i want this to work whatever changes be in the code..
can you suggest some more ways?

> can you suggest some more ways?
Uh? I suggested you a standard library function.
The way I think that is the best to use :)
