clearCache with path doesn't work

[criocere]

clearCache() if ok (no parameter)

but I use path as parameter as before in V4 (just switch from v4 to v5), the function doesn't work anymore
clearCache(null, 'Desktop|myTemplate') for exemple is ko (if I use smarty v4 lib, it works!!!)

note 0: I deleted all the cache from v4
note 1: my structure is "Desktop|myTemplate|id of my page"
note 2: I executed clearCache(null, 'Desktop|myTemplate') and I checked my cache and the folder "Desktop|myTemplate" is not deleted or emptied. Nothing happen. In V4 it was ok

Found after hours!!!
In cache creation mode I use "setUseSubDirs to true" and not when trying to empty the cache

My issue can be closed
