I'v just figured the problem out!!!!!!!!!!!
I specified the path thus
C:\Jmeter2.5\jakarta-jmeter-2.5.1\bin\${ID}.txt
The penny suddenly dropped. The path separator was being interpreted as an
escape character, and the dollar sign was then being treated literally
rather than as indicating the start of a variable to expand
So I tried escaping the last path separator like so:
C:\Jmeter2.5\jakarta-jmeter-2.5.1\bin\\${ID}.txt
and all was well :-), the variable now expands and my files are uploaded
thanks for getting back on this
