Beneath the Local Corpus window, you will find two different tabs: Files and Favourites. This section describes the Files tab and the functioning of its Working Directories, while Section 3.5 below focuses on the Favourites tab.

The Files tab is responsible for linking a folder from your computer to Arbil so that media files can be transferred into your corpus. It is advisable to have one or more folders on your computer that contains all the necessary files that you would like to upload to your corpus. This way, you can simply link this folder and retrieve all the necessary files.

The option Files is selected by default. Its Working Directories are meant to keep at hand the resources that you want to add to your corpus (such as annotations, audio files, pictures etc.). To add a new Working Directory, right click on the Working Directory node and select Add Working Directory. Now browse to the directory you want to add, select it and click again on Add Working Directory. In the figure 3.8, the directory "Recursion pics" is about to be added to the Working directories, after which you will be able to access the media files present in this folder.

Figure 3.8. Add working directories

After linking a directory to Arbil, you will have access to the folder. To import the media files (e.g. Droste.jpg) to a session of a corpus, simply drag and drop them into the desired session.

	Note
	If you right click on Working Directories, you will also see that it is possible for Arbil to show you all hidden files (option Show hidden files). This option is useful when you want to include corpus files which are normally hidden in your file manager.

Browsing through the Working Directories is very similar to browsing through the Remote or the Local Corpus. To open/close a folder click on the bullet on the left of its name or double click on the name itself. If you have added or modified the content of a directory outside Arbil, you can update such content by right clicking Working Directories and selecting Reload.

If you want to view the file information you can follow the instructions described in Section 3.2.2. (Viewing Remote Corpus Information). Remember that if you place the cursor over a file, an information window will appear that will give you a file description, including the information about whether the file is archivable or not. Archivable files can be uploaded to the server. Image 3.7 shows an example of an archivable file:

Figure 3.10. Archivable file

Editable files from the Working Directory can also be opened by external applications. Right click a given file (e.g. audio file, picture) and select Open in External Application.

If the file is not archivable, the icon will appear. If you hold the mouse pointer on the file, you will see the following information:

Figure 3.11. Unarchivable file

For the list of accepted file types and formats, check the LAMUS manual.

A file that is not supported by Arbil can be kept in Arbil anyway and still be added to a Session in the Local Corpus, thus overriding the decision of the internal type checker. To do so, right click on the unarchivable file and select Override Type Checker Decision; a pop up window will appear asking you to say whether the file is a MediaFile or a WrittenResource; the will then change into an icon of either a media file or a written resource file, and you will be able to add it as a resource file into the Local Corpus. To open the file right click it again and select Open in External Application. Beware that overriding the type checker decision can cause your corpus not to be accepted into the archive (rejected by Lamus).

In addition, if you have modified your uploaded file externally, you may want to check whether it is still accepted by Arbil. To do so, right click the file in Working Directories and select Force Type Checking. If something has happened to your file you will see its icon change.
