Every time I rename a file in Perforce it actually deletes an old file and adds a new one. As a result the new file doesn\'t share the old\'s file history.
Is there an easy way
If viewing the history in p4v, there should be an icon at the tab of the History tab that gives you the option to "Follow Branch Actions" or "Follow Both Branch and Copy Actions".
On the command line type
p4 filelog -i file
The '-i' flag will display the integration history as well.
