Just an example, what will be in this directory. All this directories are security identifiers of users, not all files in recycle.bin is your user files
You can obtain mapping of user names to sid, using management instrumentation
wmic useraccount get name,sid
Your recycled files will be in the directory with my user, but you can list all
dir /s /b
Of course, if you have more then one disk/partition in your system, your files fill be also on d:\$Recycle.Bin, e:\$Recycle.Bin etc (dependent on location of removed file)
