File Names

Use only letters, numbers, underscores, and hyphens in names of files you upload to Bb.

Files uploaded to Bb for the same assignment or page must have separate, unique names to avoid downloading problems. Adding a number or a letter to new file names will provide a unique name.

We suggest that students use their last name and an abbreviation of the assignment name for documents they upload to the Assignment Link. We also advise they remove older files before uploading newer versions of them.

What not to put in an uploaded Bb file name:
ANYTHING that is not a letter or a number or an underscore or a hyphen, i.e., do not use spaces, periods (other than the one-and-only period already used for the file extension), commas, slashes, symbols, parentheses, brackets, braces, signs, symbols, dots . . . . etc., etc., etc.

In other words, any character which is not a letter or a number or an underscore or a hyphen.

This is important.

File Sizes
Keep files small enough so users with slower connections can still download the files in a reasonable time.  When necessary, minimize file size by using an application to create a compressed (.zip) file.  These applications are often available online for free or for a small fee.  Some computers have compression applications installed or built in.

Here's a reference to help estimate download times for files:

14.4K Modem
28.8K Modem
56.6K Modem
128K ISDN, DSL, Cable

Notes

OpenOfficeNew Browser or website icon for Windows and NeoOfficeNew Browser or website icon for Mac OSX, free computer office suites of applications, will Open and Save As all formats compatible with MS Office, including PDF.

Mac OS X and Windows add the extensions automatically.
Both operating systems can have the preferences set to show the extensions.
Mac OS 9 and previous system users must add all dots and extension letters manually.
Macs usually open any file if the associated application is installed.
Windows relies on the three-letter extension and can not open files it can not identify, even if the application for that file is installed on the computer.

Contact the OIT Help Desk, L-150, 667-3687. for technical support.
