Web File Manager (WebFM) implements a hierarchical filesystem unlike the traditional flat filesystem used to date by Drupal. WebFM allows administrators to arrange files on the server in the same way they do on their local storage drives which greatly enhances the manageability of large collections of documents. Directory access is set by role and file access is controllable by file owners or module administrators.

WebFM uses Ajax to provide application intensive functionality such as drag-and-drop and context-sensitive menuing. JavaScript must be enabled for WebFM to function - functionality will not gracefully degrade for clients that have JavaScript disabled.

Installation & Configuration

File Access Setup & Examples

There are many ways to setup a file system hierarchy. The rules of any given system must be applied carefully if security of data is important.

The basic rules for users in a role with \'access webfm\' rights:

Roles with \'access webfm\' rights can be subsets of other roles with \'access webfm\' rights or they can be exclusive. Users can be members of multiple roles and will consequently have a separate left-hand tree for each unique root directory (roles can even share the same root directory). It is difficult to foresee how diverse users of the module will choose to set up their systems but the following simple examples are typical arrangements. Both examples presume that the drupal file-system directory is set to \'files\', the WebFM module is installed and the \'WebFM root directory\' is set to \'webfm\'.

Example 1

The site requires 1 class of privileged users (A) to administer the file system and 2 classes of WebFM users (B & C) with access to file resources. Both roles will be able to upload files. Some WebFM users are members of both B & C while others are members of only one. Uploaded files are by default only accessible by the file owner and admins.

Example 2

The site requires 1 class of privileged users (A) to administer the file system and 2 classes of users (B & C) with access to file resources. C is determined to be a subset of B such that B can access it\'s own files as well as those of C. C will not be able to upload files to the browser but will only be able to view/download or attach files to nodes. B will be able to upload files.

In the above examples the site administrator may simply create the roles/access rules and then let an A user configure WebFM for B & C.

Uninstall

  1. Disable the module on the /admin/build/modules page
  2. Click on the uninstall tab and select the module for removal. This will automatically drop the webfm_file and webfm_attach tables as well as all configuration variables. NOTE: This action will permanently discard all attachment and metedata information and cannot be undone. Execute the first step only if you wish to restore WebFM later without loss of data.
