Hi!
I wonder if I can calculate the SHA 256 checksum (or any other) of a file with Directory Opus?
Thanks in advance for any reply.

To answer my question: open a command prompt in DOPUS.
Enter the following commands:
certutil -hashfile SHA256
and press ENTER.
However, to have such a command in the tools menu of DOPUS would be a pleasant feature.

Directory Opus has SHA-1 and MD5 built in.
They are listed under the Edit Menu.
```auto
GetSizes SHA
GetSizes MD5
```
There are also a few scripts.
Here's one for [SHA-256 and SHA-512](https://resource.dopus.com/t/column-sha-256-and-sha-512/33525) columns.

I use [hashcheck](https://github.com/gurnec/HashCheck/releases/). It sneaks into the RIGHT-CLICK menu and also has a tab (Checksums) in the PROPERTIES option of said menu.
