Hi!
CCleaner 2.30.1130 still doesn't clean two files - one from Opera and one from Media Player Classic.
I am using Windows 7 x64 - the two files are:
# C:\Users\***\AppData\Roaming\Opera\Opera\search_field_history.dat
This file contains the search field history from Opera (I am using Opera 10.51.3315).
# C:\Users\***\AppData\Roaming\Media Player Classic\default.mpcpl
This file is a playlist containing the last file(s) played.
Before anyone asks: all options for Opera and MPC in CCleaner are switched on.
