Hi Yousef.
I know this type of functionality is desirable (and yes, even possible) but it's not really what CMOD is for. When you store one document at a time, there's not a lot of benefit to just putting it in a filesystem. In fact, you'll create a lot of overhead (database rows in the System Log, inodes in the cache, and metadata inside TSM) for very little benefit.
CMOD's big advantages are it's voracious appetite for documents that are all very much the same, with automatic indexing and amazing data compression.. not one-off uploads from end users.
You might want to consider dropping these files into Content Manager or Filenet, and once they've been through a specific workflow, archive them into CMOD for long-term safekeeping.
