[edit] Uploading Files

[edit] Uploading small files to the Resources or Dropbox tools

Files can be added to the Resources by choosing to browse for the file on your device, or on desktop computers using a modern web browser, drag files from an Explorer/Finder window into the Isaak-Sakai window.

To add files follow these steps:

  1. Actions > Upload Files
    Actions > Upload Files
    Inside your course click the Resources tool on the left.
  2. Click the Actions button beside the folder you would like to add the file to (likely the top-most).
  3. Select Upload Files
  4. Drag the file you would like to add into the Drop files.. area OR click upon the Drop files.. area to choose a file from your computer's directory.
  5. Optionally notify your students that the file has been newly added with the Email Notification menu. Note that additional file details, such as a description or custom availability dates, can only be added after upload is complete. If you prefer that students receive notifications after details have been added, consider using the Actions >> Edit Details option once the file has been uploaded.
  6. Done: You should now see the file in your course resources. You are welcome to click the file to confirm it works or modify it via the "Actions" button.

All modern web browsers support single file uploads through the drag-and-drop interface, most support full folder uploads, such a Google Chrome.

Dragging-and-dropping folders can be a faster and more reliable alterntive to situations where the WebDAV upload process might have previously been used.

For more information please see Working with files.


The Upload/Download Multiple Files option allows individuals with the correct permissions to use WebDAV to mount the Isaak/Sakai site's Resources or Dropbox area as if it were a network drive and work around the 100Mb limitation.


[edit] Attaching Files

When creating a new item, some tools such as Assignments, Messages, Forums and others, give you the option to add attachments. You can add any number of attachments, and they can be any combination of local files, web sites, and items stored in Resources. To add an attachment, follow the appropriate instructions below:

  • To attach a local file from your computer, under "Upload local file", click Browse to find and select the file on your computer.
  • To attach a URL, under "URL (link to website)", type the URL in the box provided, and then click Add.
    'Note:' You do not need to include the http:// when you type the URL.
  • To attach an item from Resources, under "Select a resource", click Attach a copy next to the file you want to add.
    'Note:' You can attach a file from one of your other sites (including your My Workspace area), provided the file's Access properties are set Display to non-members (publicly viewable). To browse for files in other sites, click Show other sites.

As you add attachments, they appear in a list under "Items to attach". When you've selected all the files, web sites, and Resource items you wish to attach, review this list, and click Remove if there are any errors.

When you're finished, at the bottom of the screen, click Continue. You should see all your items listed under "Attachments".

[edit] Things To Consider

There are a number of elements to keep in mind when uploading files to Sakai/Isaak:

  1. Individual files must be no larger than 100 Megabytes (Mb)
    • Most areas allow you to upload multiple files, thus one file 101Mb is too large, but two files that are each 99Mb are fine.
  2. Each course space can collectively only occupy 1000Mb of space.
  3. Most Internet service providers provide a faster download speed than upload speed. Be prepared for uploading to take some time.
  4. Many Canadian Internet service providers "throttle" clients who are making use of peer-to-peer technologies (file sharing, torrents), especially throttling-down client's upload speed.
    • It is good practice to stop all peer-to-peer activity while uploading to Sakai/Isaak.

[edit] Compressing

Windows XP: Right click the file in Windows Explorer/the desktop and select Send To > Compressed (zipped) File/Folder.

Mac OS X: Example of right-clicking a file in the Finder to compress it.

Most newer operating systems, such as Windows XP, Vista and Seven and Mac OS 10.4 and up, come with support for compressing files via right-clicking them. This will create a ZIP file that may be smaller than the 100Mb limit and can then be uploaded to Sakai/Isaak.


[edit] Separate large files

Most Sakai tools allow for a number of files to be uploaded/attached. By separating large works into constituant files that are less than 100Mb the 100Mb limitation can be avoided.
