Subject AW: Copiing newer files to a directory [was: using file names]
Date Wed, 13 Apr 2005 12:12:32 GMT
I forgot to mention that the files in the "target" directory have other endings that those
in "source"
e.g. a.xml => a_1.xml
b.xml => b_2.xml

Is there any kind of substring function?

wbr,
Roman
