Single Shared Instance of a File

A single shared instance of a file means that there is one master copy stored on the provider's server. Every authorised user accesses and edits that same copy, rather than each person working on their own separate file.

Because there is only one file, an organisation avoids creating and managing many copies. This saves time and reduces the risk of mistakes. For example, if you email a file to five people, you end up with five versions to merge back together. With a single shared instance, that problem disappears.

When anyone opens the file, they see the most recent version, including any changes made by others. This means users cannot accidentally work on an out-of-date duplicate. The single shared instance also makes it easier to keep everyone on the same page, because there is no confusion about which copy is correct.

Worked example: A youth theatre group keeps its rehearsal schedule in a cloud file. The director updates the schedule after each rehearsal. Every actor opens the same file and sees the latest times immediately. No one has to email a new copy or worry about reading an old version.

Without a single shared instance, each person might have their own copy, so changes could be lost or duplicated. The cloud provider manages the master copy, so you do not need to worry about where it is stored.
