Use the IFS attachment to verify the access path to the shared folder.

For those who use IFS
Please let me know if you know of any.

I am trying to save a file to a shared folder using the IFS attachment.

In the following environment, how will the files be saved in the shared folder?
Pattern 1
Are the files stored from the client to the IFS application server and then to the shared folder?

Pattern 2
Are files saved directly from the client to the shared folder?
