BOINC Data directory

BOINC stores its files (configuration files, job input/output files, etc.) in a "Data directory". The location varies with operating system:

Window

Windows

C:\ProgramData\BOINC\

This directory may be hidden. If so, paste the path into the path bar in Windows Explorer and press Enter.

Macintosh

Macintosh

/Library/Application Support/BOINC Data/

Linu

Linux

Depends on how you installed BOINC. Try

/var/lib/boinc

If you have trouble finding the data directory, go the to client message log. Near the top there will be a line similar to:

26-Apr-2010 13:08:53 [---] Data directory: /var/lib/boinc-client

The data directory has the following structure:

boinc/
notices/
projects/
boinc.bakerlab.org_rosetta
... other projects
slots/
client_state.xml
... other files

Project-specific configuration files (like app_config.xml) go in the project's directory under projects/. Other configuration files go in the top-level directory.
