Delete file

[Grincheux]

I would like how to know for deleting a file and be able to rerieve it from the dustbin.
Usually I use DeleteFile but with this function the file is lost...

How can I do ?

Use SHFileOperation with an adequate SHFILEOPSTRUCT.

When used to delete a file, SHFileOperation permanently deletes the file unless you set the FOF_ALLOWUNDO flag in the fFlags  member of the SHFILEOPSTRUCT structure pointed to by lpFileOp. Setting that flag sends the file to the Recycle Bin. If you want to simply delete a file and guarantee that it is not placed in the Recycle Bin, use DeleteFile.

Thank you for this. I did not thought to 'SHFileOperation' !
