How to change windows recyclebin properties

Question

---

How can I get this property of recyclebin and switch it using C#.

Answer 1

There is no supported way to do so irrespective of language.

As far as I understand there is no API to configure this settings. You can query information about recycle bin via PInvoke ( SHQueryRecycleBin and empty ( SHEmptyRecycleBin ).

Couple ways to touch those settings can be found in Raymond Chen's blog post - What is default size of the Recycle Bin... . Summary below:

• Official way to adjust size - via policy Maximum allowed Recycle Bin size .

• Unsupported way - tweak registry settings - Managing the Recycle bin
