I have been using CCleaner with Opera by selecting a folder manually in the "Option/Include" section because I keep my Opera cache folder in a non-standard location. In Opera 9.5 files in the cache folder no longer have file extentions. Because of this they are not deleted by CCleaner since it uses ".../cache4/*.*" to delete. Anyone know of a solution for this? I already tried to enter the path as ".../cache4/" , but CCleaner wil not accept this. The ok button is greyed out.

What if you use ".../cache4/*"

Thanks Mr. G. The new version does clean the extensionless files in the Opera cache if the cache is in the default install location. I have my machines partitioned for programs and data, and like to keep the cache files on the data partition. When I try and add my custom cache folder with "Options, Include,Add Folder" the "OK" button is greyed out unless *.* is in the box at lower left (won't accept * either). Guess I will revert to the default location unless ther is another solution.

The simplest way to clean the opera cache is to do tools->delete private data->details options and choose what you want to keep and what you want to delete.
Why do you need to use CCleaner for this task ?

Better still set Opera to delete the cache on close.
