FAQs

Sometimes File Explorer does not show user friendly and descriptive error messages from the WebDAV server. When you perform an illegal operation, for example, try to move an archived document to another case, you will only see a general error message such as: Cannot read from source or disk. Some of the Windows error messages that you might run into are explained in the FAQ items below.

You can only create new documents in specific case folders. You cannot, for example, create a new document directly in the Drafts folder, because WorkZone requires a case in order to place the document correctly in the system. If you to try add a document to the Drafts folder, the following error message will appear, depending on where you try to add it from:

A device attached to the system is not functioning.

- or -

Can't read from the source file or disk.

By default, WorkZone Explorer is not configured to allow creation of new cases. Case creation must be enabled on the SJ-TEMP class in the file class system. You apply this configuration by using WorkZone Configuration Management. If you try to create a new case, the following error message will appear:

Unable to create the folder "New folder" - File system error

Some folders do not allow case creation. You can create new cases in the Open cases folder, the Unclassified cases folder, and in specific case folders. If you try to create a new case folder in a folder which does not allow case creation, the following Windows error message will appear:

Unable to create the folder 'New folder' - File system error

See also Create case.

You are probably trying to:

• Move a document from one standard list to another.
• Move a document from a case folder to a standard list, for example, to the Open cases folder.
• Move a document to a closed case.
• Move a document that is archived or closed.

This is not possible. In these cases, following Windows error message will appear:

Can't read from the source file or disc.

It is not possible to delete folders by using WorkZone Explorer although it may look so in File Explorer. If you try to delete an empty folder, it will look as if the folder is successfully deleted, but if you press F5 to refresh, the folder reappears. If you try to delete a folder with content, nothing happens after you have confirmed the deletion. File Explorer does not display any error message in this case.

There are several renaming scenarios where the following Windows error message appears:

Can't read from the source file or disk

For example, if you try to:

• Change the document ID (DXXX) in the document name. It is not possible to change the ID; only the document name can be changed.
• Rename a document that is saved on a closed case. This is not possible.
• Rename a document in File Explorer, but the document is opened in WorkZone Client. This is not possible.

In File Explorer, if the same document is placed in different folders, each document is considered a unique and distinct document. In WorkZone Explorer, the same document can be displayed in different folders, each folder representing one way of accessing the document and referencing the same document – for example, a document might be placed in the case folder and the Favorites folder as well as appearing in a list or search.

File Explorercan only contain Folders or Documents while WorkZone Explorer can display documents, cases, searches, favorites, lists, etc. Since

File Exploreruses WorkZone Explorer functionality to display and represent WorkZone documents and elements, this means folders in File Explorer must be used to represent all non-documents (Cases, searchs, favorites, lists, etc).

When documents are moved between folders using the File Explorer drag-and-drop, WorkZone Explorer and File Explorer must synchronize data on how documents are placed and represented and sometimes File Explorer has difficulty updating document locations to represent the same document being represented in multiple folders.

This usually manifests in either an error message or the document disappearing from the folder it is moved from. You can press the F5 key to refresh the explorer or wait for about a minute for the File Explorer to update correctly.

File Explorer can display a maximum of 260 characters in paths. Therefore, if a WorkZone path exceeds the maximum number of characters, the document file names are shortened. If you open the document in WorkZone Client, you will see the full document title.

The default values of the WebDav extension to the http protocol for Windows 7 and Windows 10 are causing these issues. You can edit the default values to enable better management of large files.
