Abstract: In a method for allocating a file to a user, a first computer receives, over a network, data monitored by a second computer. The first computer comprises an IDE client. The data comprises data of usage of the file by one or more users in a group of users. The first computer receives a request to allocate the file to a first user in the group. In response to the first computer determining that, based on the data of usage, the file is allocated to a second user in the group, the first computer denies the request. The first computer adds the first user to an end of a queue identifying one or more users in the group that are waiting for the second user to relinquish allocation of the file. The first computer utilizes the data of usage to display the queue in the IDE client.
