B4J Question Moving and/or Renaming Files

You can use File.Copy and then delete the old file.

AH Thanks for the reply but wasn't the one I was hoping for.
If I understand it, under DOS copying and deleting the files is a lot more inefficient than rename and/or moving it.
Maybe I should create a .bat file and run that after the program
I have 100,000 photos I want to rename and move??????

I agree with johnB, when file(s) size(s) or number are large,it's not efficient enough to copy and del.

Not sure if I should create a new post for this????

I've tied to create a .bat file using File.WriteList

eg
for k = 0 to 100
Main.list4.Add(k)
next
File.WriteList(Main.startFolder , "Rename" & Main.txtFileNo & ".txt", Main.list4)

but it hasn't created a file where each .Add was shown as a new line in the .bat file.

I tried adding a CRLF to the end of each .Add - Main.list4.Add(k & CRLF) but this made no difference

My MFLib (see link in my signature) has a file rename function.

Thanks Manfred, I've downloaded the library, will try later. I ran the test program and everything worked ok
