Hi
the files are created by SoapUI,
the files should only be in use during an iteration across a data row, I think what is happening is that a datasource accesses the file but does not exhaust it, the test run ends then on subsequent iteration the file cannot be deleted because the ds still has it locked
at the end of an iteration (i.e. last ds loop or test run completion with either fail or success) files should be released, SoapUI appears to be doing nothing with no tests running but you cant even remove the files manually until SoapUI is closed
thanks for the pointer to the method
regards
Mike
