Spreading
A server-based routine will perform file spreading. Each indexed document awaiting spreading has an ID file (e.g. 1234456.ID) in the relevant containing its' case identifier. For each Documents Type, this routine copies files form the relevant Index Out Volume to the relevant Current Volume (q.v. Volumes), renaming as it goes. It checks the two files are the same size and then updates the database with the new volume and file name. If all is successful it the removes the original file from the Index Out Volume. If any failure occurs then any changes are reversed and the ID file copied to the relevant Spread Error Volume.

The routine creates sub folders under the Current Volume. The first level is a number corresponding to the Document Type. The next level is the year (YY) then the month (DD), then the day (DD). Expansion sub folders are created below the day (DD) folder, if more than 512 files are placed in the day (DD) folder.

For example:

02 - Unique Document type Identifier from e4DM database for the Document Type

 05 (YY)
    08 (MM)
      30 (DD)
            01 (Expansion folders)
            02 (Expansion folders)
      31 (DD)
    09 (MM)
      01 (DD)

The number of files needed to fill an overflow folder is configurable (the default is 512) and is held within e4DM.INI in the windows directory local to the server routine PC. To alter this value alter the Server section of e4DM.INI:
