How to decide Target directory dynamically?

Hi All,

I have to design a scenario wherein the sender data will have a field containing either a directory information or some kind of identifier. The receiver side is a file directory where there are multiple folders.

Ex:

/target/DirectoryStructure/

Folder1

Folder2

Folder3

.

.

.

FolderN

Now based on the sender parameter we have to decide dynamically to which folder the file has to be placed.

Ex: if Field1 value is F1 then place in Folder1

I have no idea on such an interface.

Please guide me.

Regards,
