Hi Dave,

The plan for an app that I'm doing was to use SQLite for data and to hold the 
preference settings as some apps do.  The plan was changed last week to allow 
the user to select the location of the data files (SQLite) rather than putting 
it where the OS would dictate.  Ok with that, but it brings up some questions.  
First, I will need to have a file that points to the location of the data file  
since that can't be hard coded. Second, if I have to have a file that is likely 
part of the application group of files, would it make more sense to use a more 
traditional preferences file?  How have other Python app developers done in 
this case?

We handle the "where is my config file" question by defaulting to script's 
current directory, then a script-specific folder within their home directory. Users can 
override that behavior by setting a script specific environment variable or by using a 
command line switch to point to a different location or config file.

We store our preferences in an INI style config file which we've found easier 
to support when there's problems.

Malcolm,

Thanks for the reply. I agree that a traditional INI file is the easiest way, especially since Python supports them. So if I understand you, your apps look like this:

-App Dir
  |
  +-App Code Folder
     |
     +-(File to direct to home folder)

-Home Folder (the default location, but user can select other locations)
  |
  +-App INI Folder
     |
     +-App INI file
