Destroy a file. Then find out
what actually survived.
Every shredder overwrites the bytes, deletes the file and shows a tick. That tick is frequently a lie. InShredder goes looking for every other copy first, destroys what it can reach, and grades the result honestly.
No account. No telemetry. Nothing else to install.
Real screens, real answers
Every screen below is the application as it actually looks. Black, white and grey throughout, because with no colour available inversion is what carries "this cannot be undone": the one pure white control on a screen is always the destructive one.
Look first. Destroy second. Grade honestly.
It goes looking
Restore points, cloud sync folders and placeholders, extra hard links, hidden data streams, the Recycle Bin, Office working copies, byte-identical files elsewhere, the thumbnail cache, the Windows Search index, recent-files shortcuts and File History.
You decide, with everything in front of you
Anything that would survive is shown before you commit, not after. Copies arrive ticked so they go with the original, and anything you untick is left completely alone.
It tells you how it went
Contents, file name, timestamps, hidden streams and the unused tail of the last disk block. Then a grade, and a certificate naming the standard actually performed.
Four answers, and one of them is "no"
A grade C is this application doing the one job the others refuse to do. It is never softened into a tick.
Reached everything
Overwritten, read back and confirmed, on a drive where that replaces the original.
Flash storage
Everything reachable was destroyed, but remnants inside the device cannot be ruled out.
A copy survives
Gone from here, but a copy of it still exists somewhere that can be named.
Not destroyed
It did not happen, and the reason is listed against the file.
Built for the file you cannot leave behind
The parts others miss
The file name lives in the folder index, not in the data, so it is destroyed separately. So are the timestamps, any hidden data streams, and the unused tail of the last disk block.
The cases that defeat a naive shredder
A compressed or sparse file, whose overwrite would land in fresh blocks and leave the original intact. A file small enough to live inside the file table, with no blocks to overwrite at all.
Identical copies, found by content
Select "report - Copy.pdf" and it notices "report.pdf" beside it, matched byte for byte rather than by name.
The Recycle Bin, properly
What is in the bin is filed, not deleted. Both halves go: the data, and the record naming where it came from and when.
Drive-level erase
ATA Sanitize, ATA Security Erase, NVMe Sanitize and NVMe Format, where the hardware supports them. It reports what each drive actually supports.
A record, or none
An encrypted history and a Certificate of Sanitization. By default it stores a salted hash of each path, because a list of the confidential files you destroyed is itself a confidential file.
The truth about SSDs
On a mechanical hard disk, overwriting a file replaces it. On an SSD or a USB flash drive it usually does not: the controller writes your new data somewhere else and marks the old location free, and the original cells stay readable to anyone who can address the chips directly.
Wear levelling, over-provisioning and retired blocks are all out of reach of any software running on Windows. InShredder says so, on the screen, every time, and caps the grade at B. No other shredder claiming a "military grade" wipe will tell you this.
- Standards, not adjectives. The phrase "military grade" appears nowhere in the application. It implements NIST SP 800-88 Rev.1 Clear, and Purge through the drive's own firmware where supported.
- No Gutmann. Thirty-five passes designed in 1996 for drive encoding that no longer exists. An option nobody should choose does not belong on the menu.
- It refuses things. Drive roots, system folders, your main user folders themselves, network locations, and anything reached through a junction.
- Nothing leaves the machine. No account, no telemetry, no analytics. One optional update check sends the name and version, and switching it off means it never touches the network at all.
Make it gone, and know that it is
Free, offline, and self-contained. Windows 10 or 11, 64-bit. Nothing else to install.
There is no undo. No quarantine, no Recycle Bin, no recovery of any kind. That is the entire point of it.
