When a session is created from an instrument, several session-specific subdirectories will be created
under this (dsurvey\sessions) directory. 

For simplicity sake, assume the name used for a session is "mySession".

The following files and subdirectories will be created.

     sessions\mySession.XML   : session specific descriptor file (this starts as a copy of the instrument descriptor file)
     sessions\mySession       :  directory for storing session specific parameter files, results (i.e.; submitted data), etc.

Assuming you created an instrument using the Create An Instrument option on the dSurvey main administration page
(dsurvey/admin.htm), the following files will be created when a session is created.

   sessions\mysession\allowedUsers.xml
   sessions\mysession\control.xml
   sessions\mysession\params.xml
   sessions\mysession\reference.xml
   sessions\mysession\describe.txt 

There may also be several sc*.xml (scenario) files.

See the dsurvey\instruments\read.me for details on these files.

Also, a sessions\mysession\backup subdirectory will be created. 
This can be used for storing backups, and is not necessary for normal operation of dSurvey.

Note that while a session is running, several other files may be created.

These include:
  notes.txt : for storing notes written by an administrator
  joinlist.txt  : list of current participants
  saveSnapShot.xml  : a snapshot, taken by an administrator, of the current state of a session



On projects:
  If a session name starts with:
     $aproject_aname
  Then  "aproject" is the "project" that the "aname" session "is in".
  "Projects" are used to form a hierarchy, with sessions being general (not in a project), or "in a project".
  This is simply a way of simplfying display, when there are lots of sessions.
  Note that sessions can be created in projects that have the same name as the instrument's project, or a 
  different name.
