Alice Worlds are really BIG. Typically, a file containing an Alice World requires 2 - 10 megabytes and more storage. If you wish to backup and transport your Alice files, you are advised to purchase a USB 2.0 compatible flash drive with a capacity of 128 MB or more. In Calgary, flash drives can be purchased from various vendors. Without prejudice, you may compare prices at Calgary vendors such as:
"Compare apples to apples and oranges to oranges."
Ensure that you compare prices on precisely the same product and capacity (128 MB - 256 MB - 512 MB - 1 GB - 2 GB).
