Using temporary files
How to Use Temporary Files
When using batch files, you may often want to use a temporary
file to hold your work. You could use the same name each time
you wanted to use a temporary file.
However, if you are using more than one batch file that uses the
same temporary file, you might lose the contents of this tem
porary file. To avoid this problem, you should use a replaceable
parameter to specify the name of the temporary file. Then each
time you run the batch file, you'll be able to substitute a unique
filename and you won't have to worry about information from
one batch file getting into another.
It's also a good idea to delete temporary files once you finish
using them. Otherwise, these files would eventually take up all the
space on your disk.
