delete keywords in Bridge v15.1.0.635

Keywords are in two places:

1) File level metadata 

2) Adobe Bridge Keyword panel.

The Keywords panel offers editing features, however, if you need to make manual backups or edits of the underlying XML...

On the Mac OS, the location of the Adobe Bridge Keywords.xml file will be similar to:

/Users/loggedinusername/Library/Application Support/Adobe/Bridge CC 2015/Adobe Bridge Keywords.xml

Mac users should simply replace “loggedinusername” and “Bridge CC 2015” with the appropriate user name and version of Bridge.

On MS Windows, the path to the Adobe Bridge Keywords.xml will be similar to:

C:\Users\Loggedinusername\AppData\Roaming\Adobe\Bridge CC 2015\Adobe Bridge Keywords.xml

MS Windows users should replace the “Loggedinusername” and “Bridge CC 2015” with the appropriate user name and version of Bridge. It should be noted that the AppData directory may be a hidden folder for some users.

Make a backup copy before editing the XML file.
