Hello Kalyan, hello Sri,
thank you for your posts 
. Actually we have the temp file feature and I will check the default name scheme for those.
Regarding the ping I am not so sure. It does the following two tests (ping for file receiver channel 6.40):
| Destination Directory Writability Test | Directory "/..." is writable | |
| Receiver Agreement Existence Test | Binding exists with interface ".." and namespace ".." |
What does the adapter do to test the Directory writability? We've actually been assuming it does wrote selftest*java files and immediately deletes them.
Thank you for further feedback
Mark
