My thanks to anyone who reads and replies to this

I have written a macro which does a number of things:

1) Writes a number of script files for a third party software product
2) Writes a .bat file to execute the scripts
3) Loops until the resulting output files are found
4) Imports the files (text files
5) Copies the required data into my spreadsheet
6) Closes the txt files (SaveChanges = False

The problem I have is that when the macro completes, a few seconds later, an Excel popup proclaims "The file "####.txt" is available for read/write" for each of the txt files previously imported and closed

Why? and, how can I prevent this happening

Thanks again.
