    You need to download or buy some disk wiping software. If you have an SSD you need to get one that says it can work especially for SSDs (Though maybe using the max number of passes might work as well).

    So look on google for Disk Wipe and there'll be a lot of things to choose from. NOTHING in windows itself will do this.

    What is the meaning of SSD?

    Could you please specify some freeware for windows?

    IS it true? I found below lines about unrecoverable files.

    Any tool that overwrites the data is ultimately going to stop casual attackers (and, very likely, even well budgeted attackers). Recovering data from an overwrite on modern hard disk drives is extremely difficult. You can use as fancy a tool as you want (overwrites data with a cryptographically sound random number generator, etc), but in the end even a simple overwrite with zeros will protect you from all but the most sophisticated attackers.
    Beware of SSDs and attempting to overwrite data. SSDs do "wear leveling" and tools that simply overwrite files without any awareness to the underlying storage technology may not actually overwrite the data.

    SSD is solid state drive. It is a drive that uses flash chips instead of spinning magnetic platters. If you have one, then you will have to use a special utility from the drive manufacturer to wipe your drive. If you have a normal HDD, you can use Eraser to delete the files.

    SSD = Solid State Drive.

    And yes that's true, there is a lot of "extra" space on an SSD that is rotated in and out of service as needed to maintain high throughput at all times. It's a sort of ongoing small scale defragging active at all times. But that means that a single pass wipe will not necessarily wipe out all data on the drive, there may be another 5-10% of "old" data left sitting in the currently unused areas.

    Now I think that normally when one of these new areas comes back into service it is immediately and completely overwritten by new data, but still, would be best to get one that said it specifically handled SSDs (if you have one). Or run multiple passes, though even then that might not do it, the rules for rotating spare memory into and out of service are quite complex

    I cannot personally recommend any one tool over another myself. Maybe some others have more experience, sorry.
