File Shedder

Hi,

I use Alternate File Shredder for secure deletion
I can't shred huge files because their size increases continuously
No problem with Windows Explorer

I contacted Alternate File Shredder developer and I didn't receive an answer

What is increasing their size?

I don't understand where Opus is involved here.

(Opus has its own built-in secure delete function if you don't need anything particular that the other tool does.)

My question it's just a last attempt to solve this issue. I have asked this question hoping that some experienced user could suggest me an Opus setting that can prevent this issue.
I know it's not an Opus bug, sorry if I offended you.

However, the problem is related with files bigger than 1,5 GB, the shredding process is endless and the size of the shredded file increases continuously

It might be worth looking at what happens using Process Monitor. Something must be extending the file so it'd be interesting to see what.

If it shows dopus.exe is doing it, check the Stack Trace option for some of the events to see if it's actually Opus or a DLL that's part of the shredder tool and loaded into the dopus.exe process. Depending on how it is written, it may work within the host process or it might send the task out to a separate process.
