Option for "File System" folder cleaning in Google Chrome and Opera

Some file share resources, for example Mega(moderator edit), uses new approach (which is available in HTML5) to download files, they use sandboxed section of browser's local storage, files are downloaded in following sandboxed section's folder(s):

for Google Chrome:

C:\Users\[USERNAME]\AppData\Local\Google\Chrome\User Data\Default\File System

and for Opera:

C:\Users\[USERNAME]\AppData\Roaming\Opera Software\Opera Stable\File System

After that, browser pop-ups usual file download window and just copies file to download location, but file in File System folder stays there (without extension) and if do not delete them manually, file system folder can grow indefinitely depending how much such types of download is used.

Only App which I found can clean this automatically is HotCleaner but, it has to be installed as browser extension for individual browsers, it wold be nice if CCeaner had ability to clean File System

(Moderator edit: removed unneeded links. Judged Hotcleaner not to be a direct competition product, other moderators may over rule -nergal)

you can try Winapp2.ini which include /File System directory and more cleaning rules

Thank you for INI file.

But still, this is good for advanced users, not for everyone

I checked on several PC's, even with this ini file, "File System" folder remains intact
