Sorry, hash was meant to be <file name without the path>, so given the
ppt: c:\temp\test.ppt is 23456 bytes in size and last edited on the
first second of 1 Jan 2018 the hash would be:


Or some binary equivalent for the size and date.

  Powerpoint is slow to load

Status in OpenLP:

Bug description:
  Originally reported in forum:

  The problem is that when we load a PPT we generate thumbnails for the preview 
and the slidecontroller, and extract notes and titles for showing on the stage 
view. This data is stored in a folder which name is a md5-hash of the full path 
of the ppt-file.
  When a presentation is placed in the servicemanager, the file is copied to 
the servicemanager folder, and when going live OpenLP creates a hash of the new 
full path of the file (now in the servicemanager folder) which of course is 
different from the old hash, and therefore OpenLP generates the thumbnails etc 

  A few solutions could be made:
   * Make the hash based on the file content instead of the file path (might be 
a bit slow on big files).
   * When adding a ppt-file to the servicemanager, copy the old folder to the 
new hash-folder.
   * Add the thumbnails etc to the service file.
