How to permanently delete files, not just hide them
If you are searching for how to permanently delete files, you have probably learned that emptying the Recycle Bin is not enough. Neither is Shift+Delete. Both tell Windows the space is free and drop the entry pointing to it, but the bytes stay where they were until something new happens to land on top. Recovery software reads those leftovers, which is why a deleted file can come back weeks later.
The only way to defeat that is to overwrite the contents before the file is removed. File Shredder does exactly that and nothing else. There are no wipe methods to compare and no pass counts to pick. Drop the files, press Shred, confirm once, and they are destroyed.
Shred files in three steps
- Drag files or folders onto the window, or use Choose files or Choose a folder. A folder brings in everything inside it, subfolders included.
- Check the count and total size the app shows, along with the reminder that nothing goes to the Recycle Bin.
- Press Shred and confirm. Each file is reported as it goes, and the count turns to gone for good when the batch is done.
What happens to a shredded file
Every file gets three overwrite passes: all zeros, then all ones, then random data. Each pass is flushed to the disk before the next begins, so the passes really reach the drive rather than sitting in a cache.
The file is then cut to zero length and given a random 12-letter name before it is deleted. That last part matters more than people expect: a leftover directory entry called Tax return 2025.pdf gives away what was there even when the contents are gone.
Read-only files have the flag cleared and are shredded like any other. A file that another program holds open cannot be written to, so it is left alone and listed with the reason, never skipped in silence.
Can permanently deleted files be recovered from an SSD?
On a traditional hard drive, overwriting a file in place replaces the old data. Solid-state drives work differently: the drive's controller spreads writes around to save wear, so an older copy of a block may survive somewhere that no Windows program can address. File Shredder overwrites the file as Windows presents it, which is as far as any software can reach, and it does not promise more than that on an SSD.
For an SSD you are retiring or giving away, pair shredding with full-disk encryption or with the drive maker's own secure-erase tool.
