According to this post - scroll down to "CCleaner v2.29"

... Multiple File Types in one Include/Exclude entryPrior to CCleaner v2.29, if you wanted to specify file types in
CCleaner’s INI file using Include or Exclude, you had to specify
each file type on a separate line. This had the effect of slowing
CCleaner down, since it had to run multiple scans. With v2.29, you
can now specify multiple file types within a single Include or
Exclude line. Here’s the syntax:IncludeX=TYPE|Path|extension[;extension][|RECURSE]
…
This works in winapp2.ini as well.
Try this syntax:
FileKeyx=path|file1.ext;file2.ext
Since the blog post doesn't specify I guess I should ask
if this is a supported use of this feature.
