The developer of BleachBit; a popular Windows/Linux disk cleaning utility, earlier received a firm request from Piriform; the developers of CCleaner, to remove a feature that allows BleachBit users to import custom cleaning rules created by the community.
The cleaning rules in question is the Winapp2.ini file compiled by Robert Ward, who is unaffiliated with Piriform. It’s also the same file used by CCEnhancer to add extra entries to CCleaner. System Ninja is also capable of parsing the contents of Winapp2.ini to improve its cleaning power – you can see why I have a vested interest in the outcome of this saga.
Piriform don’t own the file that BleachBit is supposedly forbidden from parsing. Winapp2.ini is entirely authored by the community; meaning Piriform can claim no ownership over it. They have no grounds to argue that they own the syntax/format of the file either, as CCleaner-compatible cleaning rules (such as Winapp2.ini) use a fairly standard implementation of Microsoft’s INI/CONFIG format.
