With File Shredder you can remove files from your hard drive without fear they could be recovered. There are quite a few software tools today for retrieval of deleted files under Windows OS. Those tools, often referred to as "file recovery" software, are taking advantage of shortcoming of WIndows "delete" command that we all use regularly to delete files. Actually, the "delete" operation in Windows only removes bits of information from files so they appear deleted in OS. It is easy to retrieve those files using aforementioned specialized file recovery software.

In order to remove, or shred files permanently from your system you have to use a program that is capable of rewriting the files with random series of binary data multiple times. This process is often called shredding. That way, the actual content of the file has been overwritten and the possibilities to recover such a shredded file are mostly theoretical.
File Shredder has been developed as fast, safe and reliable tool to shred company files. The author of this program released it free under GNU licence and you are welcome to download File Shredder and use it without any restrictions. File Shredder is simple but powerful program that surpasses manu commercial file shredders out there. The Author believes that such a utility should be available to anyone for free and that permanent and safe removal of confidential documents is a matter of basic right to privacy.
For more comprehensive protection you can download ArchiCrypt Shredder. It is very powerful commercial application suite which doesn't stop on shredding utility and is priced incredibly low for what it offers. If you don't need all the options of ArchiCrypt shredder and prefer separate utilities for important tasks some of best commercial utilities are produced by Blancco. They have really good Data Cleaner for shredding the whole volumes (Hard Disks) and that is something my File Shredder utility is not supposed to do - yet. But the best overall suite of privacy protection tools I've stumbled upon is from CyberScrub, they have a rock solid and full featured set of applications including data destruction, evidence cleaner, password manager and antivirus.
There are several drawbacks to using this program, and the information on their download page has a fair discussion of those issues. We suggest using any of these other file shredder programs before trying this one.
When your computer is getting full, BleachBit quickly frees disk space. When your information is only your business, BleachBit guards your privacy. With BleachBit you can free cache, delete cookies, clear Internet history, shred temporary files, delete logs, and discard junk you didn't know was there. Designed for Linux and Windows systems, it wipes clean thousands of applications including Firefox, Adobe Flash, Google Chrome, Opera, and more. Beyond simply deleting files, BleachBit includes advanced features such as shredding files to prevent recovery, wiping free disk space to hide traces of files deleted by other applications, and vacuuming Firefox to make it faster. Better than free, BleachBit is open source.
The only way to ensure that deleted files, as well as files that youencrypt with EFS, are safe from recovery is to use a secure deleteapplication. Secure delete applications overwrite a deleted file'son-disk data using techniques that are shown to make disk dataunrecoverable, even using recovery technology that can read patterns inmagnetic media that reveal weakly deleted files. SDelete (SecureDelete) is such an application. You can use SDelete both to securelydelete existing files, as well as to securely erase any file data thatexists in the unallocated portions of a disk (including files that youhave already deleted or encrypted). SDelete implements the Departmentof Defense clearing and sanitizing standard DOD 5220.22-M, to give youconfidence that once deleted with SDelete, your file data is goneforever. Note that SDelete securely deletes file data, but not filenames located in free disk space.
SDelete is a command line utility that takes a number of options. Inany given use, it allows you to delete one or more files and/ordirectories, or to cleanse the free space on a logical disk. SDeleteaccepts wild card characters as part of the directory or file specifier.
Securely deleting a file that has no special attributes is relativelystraight-forward: the secure delete program simply overwrites the filewith the secure delete pattern. What is more tricky is securely deletingWindows NT/2K compressed, encrypted and sparse files, and securelycleansing disk free spaces.
Cleaning free space presents another challenge. Since FAT and NTFSprovide no means for an application to directly address free space,SDelete has one of two options. The first is that it can, like it doesfor compressed, sparse and encrypted files, open the disk for raw accessand overwrite the free space. This approach suffers from a big problem:even if SDelete were coded to be fully capable of calculating the freespace portions of NTFS and FAT drives (something that's not trivial), itwould run the risk of collision with active file operations taking placeon the system. For example, say SDelete determines that a cluster isfree, and just at that moment the file system driver (FAT, NTFS) decidesto allocate the cluster for a file that another application ismodifying. The file system driver writes the new data to the cluster,and then SDelete comes along and overwrites the freshly written data:the file's new data is gone. The problem is even worse if the cluster isallocated for file system metadata since SDelete will corrupt the filesystem's on-disk structures.
The second approach, and the one SDelete takes, is to indirectlyoverwrite free space. First, SDelete allocates the largest file itcan. SDelete does this using non-cached file I/O so that the contentsof the NT file system cache will not be thrown out and replaced withuseless data associated with SDelete's space-hogging file. Becausenon-cached file I/O must be sector (512-byte) aligned, there might besome leftover space that isn't allocated for the SDelete file evenwhen SDelete cannot further grow the file. To grab any remaining spaceSDelete next allocates the largest cached file it can. For both ofthese files SDelete performs a secure overwrite, ensuring that all thedisk space that was previously free becomes securely cleansed.
On NTFS drives SDelete's job isn't necessarily through after itallocates and overwrites the two files. SDelete must also fill anyexisting free portions of the NTFS MFT (Master File Table) with filesthat fit within an MFT record. An MFT record is typically 1KB in size,and every file or directory on a disk requires at least one MFT record.Small files are stored entirely within their MFT record, while filesthat don't fit within a record are allocated clusters outside the MFT.All SDelete has to do to take care of the free MFT space is allocatethe largest file it can - when the file occupies all the available spacein an MFT Record NTFS will prevent the file from getting larger, sincethere are no free clusters left on the disk (they are being held by thetwo files SDelete previously allocated). SDelete then repeats theprocess. When SDelete can no longer even create a new file, it knowsthat all the previously free records in the MFT have been completelyfilled with securely overwritten files.
The reason that SDelete does not securely delete file names whencleaning disk free space is that deleting them would require directmanipulation of directory structures. Directory structures can have freespace containing deleted file names, but the free directory space is notavailable for allocation to other files. Hence, SDelete has no way ofallocating this free space so that it can securely overwrite it.
In order to delete files permanently, you have to use file shredder software which helps you to shred files and folders from your Windows drive. It shreds the deleted data leaving no traces of sensitive/critical data.
Once the files and folders has been wiped using File Shredder Software, it is highly impossible to restore them. The files will be deleted permanently as the software overwrites the data and the sectors holding deleted or normal data using standard or selected shred patterns.
The reason being, software needs to scan the complete logical drives in order to build the hierarchical structure of files and folders. Scanning time depends on the amount of data on a logical drive. Once a tree has been formed, software will take much less time to load the tree on subsequent uses.
When you select Recycler folder for shredding, the windows operating system might take a while to complete, depending on the system configuration. This is usually caused by an unusually large amount of files in the root of the recycle bin. In order to list the paths of the files to be shredded, a lot of processing power is required by the File shredder.
No, File Shredder is designed to shred files and folders inside a logical drive. It shreds the files in a systematic way, so that shredding process would not affect the file system of the logical drive.
To force delete folder: It is recommended trying Shift + Delete to permanently delete a file or folder. Besides this shortcut, Command Prompt, Safe Mode, and third-party file shredder software can give a back.
There are times you mistakenly deleted a needed file on your Windows 11, 10, 8.1, 8, 7 computers, we also provide you with additional help. You can recover deleted files with easy-to-use data recovery software. EaseUS Data Recovery Wizard is my recommendation. It is the best file recovery software that allows you to:
The software will automatically start scanning all over the selected drive. When the scan completes, select the "Deleted Files" and "Other Lost Files" folders in the left panel. Then, apply the "Filter" feature or click the "Search files or folders" button to quickly find the deleted files. 2ff7e9595c
