What is ZZZ file?

File extension .ZZZ, fully named CCleaner Securely Deleted File, is a file type created by a program called CCleaner used for computer maintenance.

CCleaner is a utility program, developed by a software company named Piriform, which helps to optimize computers performance by removing temporary, unnecessary and unwanted programs and files – freeing up disk space and making sure operating system runs faster and much smoother, lowering the level of potential threats from malicious programs and codes.

After scanning for issues and deleting process is finished, CCleaner creates a file type with .zzz extension. The file itself contains information about securely deleted items, serving somewhat as a storehouse with all of the unwanted files in one place.

Storing deleted files that have been successfully wiped from the computer enables not only more improved and optimized computers performance but also increased security since the all of the original filenames no longer exist.
