Perforce changelists are lists of actions performed on files. When you open files for add, edit, or delete, integrate them, or schedule them for resolve, the files are added to changelists. The actions in the changelist are performed when you submit them. Pending changelists are changelists that have yet to be submitted.
Changelists are numbered by the Perforce server, to uniquely identify them; in addition, a default changelist is maintained for each client workspace. Note that, if submission of the default changelist fails, the server assigns it a number.
Changelists are displayed in the Specs pane, on the Pending and Submitted tabs. By default, all the pending changelists for all client specifications are displayed on the Pending tab.
To filter the displayed changelists, use the filter drop-down box above the changelist pane. For example, to display all changelists that affect a file, drag the file from the Tree pane to the filter drop-down box above the changelist pane.
To display the details about a changelist in the pane, double-click it.
To move a file from one pending changelist to another, expand the source changelist and drag the file to the target changelist.
To minimize the time it takes P4V to handle very large changelists, limit the number of files displayed in a changelist by doing the following:
