Comment 10 for bug 569261

Please excuse me for being a novice, but I became a victim of this bug ever since I upgraded from Helena to Isadora and restored my backed up files a few months ago. Locked folders have caused issues with certain programs. On occasion, I've managed the issue by restoring permissions to myself using the GUI.

Can anyone recommend a more efficient method for unlocking a folder and all its sub-folders? Thanks in advance!
