BOINC Data directory

From BOINC

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

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
/Library/Application Support/BOINC Data/
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.
