By iris, Updated on 2012-09-26 19:16:40

When you delete files from your computer and even empty the Recycle Bin, Windows only deletes references to the files from the file system table but the contents of all deleted files remain on the disk that gives an opportunity to restore files to their original location. So you need some powerful file deletion tools to completely and permanently delete files. Here are several file deletion software to delete files permanently. These file deletion software help to securely delete files so that file recovery software cannot recover deleted files.

1. File Shredder of Glary Utilities is free file deletion software that securely deletes your files from the hard disk permanently. The program ensures permanent deletion of files and data from your system memory so that no one can recover your vital information. You can also use this application to securely delete files from Recycle Bin. The freeware simple scans your system and overwrites every unoccupied space found by it in your disk.

2. Eraser is free file deletion software designed for secure deletion of files permanently from your disk. The freeware erases files, folders and their previously deleted counterparts. You can securely delete your most sensitive data from your disk so that others do not peep into your unshared life. This advanced permanent file deletion software allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. It comes with customizable scheduler so that you can periodically run the program on your system and it will timely overwrite your system memory so that all your free reference are overwritten and protects you from data thefts.

3. SDelete is free file deleting program for Windows. The application is rather in advanced mode and requires little knowledge about the file allocation and deletion of files and data. If a deleting program writes to an existing unoccupied portion of deleted file, NTFS allocates new space on the disk to store the new data and after the new data has been written, deallocates the clusters previously occupied by the file. Thus, overwriting such a file will not succeed in deleting the file’s contents from the disk. In order to overcome this obstacle this freeware relies on the defragmentation API. The application search for compressed, sparse, and encrypted files and on finding the clusters than it opens the disk for raw access and overwrites those clusters.
