Configuration Files location changes since v1.18

The APP_DATA folder is used by BitComet since v1.18. A new option ”system.use_app_data” has been added to the Advanced page of the Options dialog. Users can switch the configuration folder of BitComet using this option.

For a new installation

If installed in PROGRAM_FILES folder, the default configuration folder will be in APP_DATA; otherwise the default configuration folder will be the installation folder. The latter situation is useful when installing BitComet in a removable USB disk.

For an upgrade

BitComet will seek and find the existing configuration files in their current installation1) folder, and their installation folder will continue being used as the configuration folder, no matter if it's the PROGRAM_FILES folder or not.

For multiple installations in a computer

BitComet will try to seek and use the configuration files in the current installation folder at first. If not found, it'll try to search for them in the APP_DATA folder. If still not found, it'll create new configuration files as in a new installation, in the APP_DATA folder or installation folder.

How to downgrade

Check the option ”system.use_app_data” in the Advanced page of the Options dialog. If it's set on true, disable it (set it to false) to have all configuration files moved back to the installation folder. After that, reinstall the old version of BitComet, and it should work properly.


Main Index

1) In Windows Vista or Windows 7 if BitComet was installed in the Program Files folder then by “installation folder” should be understood the \Users\%userprofile%\AppData\Local\VirtualStore\Program Files\BitComet folder, as all configuration files will be found there. This is independent of BitComet and due to the data virtualization feature introduced in Vista and will happen to any application which tries to write its configuration files in Program Files or any other system folder, for that matter, while not using elevated privileges.
