How can I move file into Recycle Bin / trash on different platforms using PyQt4?

Question

I would like to add the next feature to my cross-platform PyQt4 application: when user selects some file and select "remove" action on it that file will be moved to Recycle Bin folder instead of being permantly removed. I think I can find Windows-specific solution using Win32 API or something similar, but I'd like to know does similar operation could be executed on Ubuntu/Linux and MaxOSX as well via PyQt4 methods.

Answer 1

It's a good thing you're using Python, I created a library to do just that a while ago:

http://www.hardcoded.net/articles/send-files-to-trash-on-all-platforms.htm

On PyPI: Send2Trash

Installation

Using conda:

conda install Send2Trash 

Using pip:

pip install Send2Trash 

Usage

Delete file or folders

from send2trash import send2trash send2trash("directory") 

Answer 2

I guess there really is no cross-platform solution provided by Qt and it's not a totally trivial task to implement the trash concept in Linux since it's slightly different based on which file manager is in use.

Here's a site discussing the trash concept in Nautilus and another one for KDE.

Under Windows you can use the Win32 API like you said. Python solution available here.

Mac OS X puts the trashed files in ~/.Trash similar to other *NIX OSes, but I couldn't quickly Google any documentation for it. It seems that the OS X trash info file is some kind of binary format and not plain text like in Linux.

Symbian doesn't have a desktop concept and thus no trashcan concept either. It might be similar for other mobile platforms.

EDIT: Super User has some discussion revealing that .DS_Store does indeed store information about trashed files, but no specifics about the format.
