O que você está vendo é a lixeira das pastas "Meus Documentos" redirecionadas.
O problema está bem descrito no artigo Redirecionamento de pasta de documentos / Lixeira :
When using folder redirection to redirect users My Documents folders, items deleted from the user's My Documents folder are stored in a Recycle Bin in the user's My Documents folder [which lives on a server]. Unfortunately the maximum size of the Recycle Bin is based on the size of the drive the My Documents folder has been redirected too. The default size is 10%. Using the Policy maker registry client and Group Policy I have pushed the necessary settings to make the maximum size of the Recycle Bin for the My Documents folder 1%.
The problem is that 1% is still way to big. The drive being used to store redirected My Documents is currently 500GB. 1% of that is 5GB, compound that with about 2000 users and it's clear that over the years we could be potentially storing a lot of unnecessary files. Teaching or instructing 2000 users to purge their My Documents folder on a regular basis simply isn't possible.
O artigo Redirecionamento de Pastas & Lixeira diz isto:
If you redirect "My Documents" Recycle Bin can become an issue (wasting tons of expensive server disk space).
You can control Recycle Bin behavior with this registry key:
HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\BitBucket
,NukeOnDelete=1
would disable usage of Recycle Bin for Redirected Folders.
Existe outro item chamado UseGlobalSettings
que tem o valor 1
se esses parâmetros forem usados para todos os discos. Com o valor 0
,
os parâmetros da lixeira para cada disco são encontrados como sub-chaves
drive-letter do disco.
No entanto, há outro problema levantado nesse artigo:
This NukeOnDelete key is really nice. However, I bring forth another conundrum... After redirecting My Documents, the user will have two Recycle Bins - one for local files, the other for redirected files. When the user browses to the Recycle Bin it automatically loads the redirected My Documents, but I can't find out how to access the local Recycle Bin. I understand that the local Recycle Bin is C:\Recycler, but it directory always appears empty. I know in the ideal environment, users shouldn't have access to delete files from the local system. There must be a way to allow the user to access the local Recycle Bin after redirecting My Documents (other than disabling the redirection and log out/in)...
Mais informações do artigo acima sobre como controlar os tamanhos das lixeiras:
- The MaxCapacity value is located at
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\BitBucket\KnownFolder\<GUID>
- In our environment, we only redirect the Desktop and Documents folders to the server. The GUIDs for these are (the others are located at http://msdn.microsoft.com/en-us/library/bb882665.aspx):
- Desktop: B4BFCC3A-DB2C-424C-B029-7FE99A87C641
- Documents: FDD39AD0-238F-46AF-ADB4-6C85480369C7
- As an example, to set the redirected Desktop folder to only use up to 200mb, apply the following registry value:
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\BitBucket\KnownFolder\{B4BFCC3A-DB2C-424C-B029-7FE99A87C641}\MaxCapacity=0xC8
(0xC8 is 200 in hex)- I used Group Policy Preferences to push these changes out to our environment.
- In my testing, this did not immediately purge items in the Recycle Bin that were larger. However, when I deleted a new item after this registry setting had been applied, the older items were immediately deleted from the Recycle Bin.
Quanto a excluir esses arquivos: Isso excluirá documentos excluídos da lixeira do usuário, portanto, pode não ser um problema muito grande. Exceto que ele poderia desperdiçar as configurações da lixeira especificando arquivos que não existem mais. Pode ser melhor esvaziar a lixeira geral imediatamente depois de excluir todos esses arquivos.
Francamente, os Meus Documentos redirecionados parecem ter sido ridicularizados pela Microsoft. Você terá que pisar delicadamente entre as armadilhas.
