Removing junk files is not only safe, it can also help to speed up your PC or optimize your Mac by decluttering your drive and freeing up disc space. To get rid of junk files completely, move them to your trash and then empty it.
Even if you immediately empty the Recycle Bin or Trash folder, all your deletion does is earmark the space that file takes up on your hard drive as vacant. Until another file or application comes along to make use of that room, the old data will remain.
During PC reset, if you select only "Just Remove My Files," it performs a quick format to delete everything that is saved on your computer. It also deletes the file tables that consist of pointers related to the data files.
The possible causes can be: Too many applications or files saved on the disk. There is not enough disk space. File system corruption on the hard drive.
Junk files are temporary files created so your computer or phone can perform specific tasks and that are now no longer needed. At one time, these files were helpful, because programs, apps, and operating systems need to create temporary files to execute computing tasks.
