When using the Mail app on the Mac, you can accumulate a lot of attachments over time. Cleaner merges this function into the iTunes cache-cleaning function, because this function is too simple to separate out for display. But for infrequent iPhoto users, this feature is somewhat superfluous.
We can say that this kind of space consumption is a double-edged sword, since browsing is speeded up. When iPhoto users synchronize their phone camera with the computer terminal, it creates residual cache files that speed up photo browsing for the user, but also increases the burden on disk by using up space. Moreover, a single language pack is very small and does not significantly affect the entire disk space. Cleaner supports the cleanup of user cache and system files, but stops at removing application language packs due to safety considerations: for certain software, there might be program errors once the language pack is removed. Is there an app that provides that 80 percent? Of course, there is.
