You should always delete or unload a task stream after you are done with it.
Your Perforce administrator should also run a batch process to delete or unload inactive task streams on a regular basis.
Note that any submitted files remain in the depot even after you delete a task stream.
Note also that you cannot re-use the names of deleted task streams.
To delete a task stream:
Context-click the stream in the Streams tab (in graph, tree, or list view)
Select Delete Stream 'stream_name'.
Unloading transfers infrequently-used metadata from the versioning engine's database files to a set of flat files in an unload depot. If you unload a task stream, you can reload it if you change your mind and want to use it again.
To unload a task stream:
Context-click the stream in the Streams tab (in graph, tree, or list view).
Select Unload stream 'stream_name'.
To reload an unloaded task stream:
Display the Streams tab in List or Tree view.
Select the Unloaded Unloaded... icon in the filter pane to open the Unloaded Streams dialog, where you can filter for and select unloaded streams to reload.
Context-click the stream and select Reload Stream.
Unless the stream is a task stream, deleting the stream only deletes the stream specification, not the files that have been submitted to the stream.
The files submitted to the stream are part of your permanent history; you want to keep them!
I often find myself referring back to the change lists and diffs of changes made many years ago, sometimes even decades ago, so I do everything possible never to erase old history.
If you really wish to destroy the permanent history of changes made to this stream, you can use the 'p4 obliterate' command, but be aware that this command cannot be undone.
If you are contemplating using obliterate to destroy the files submitted to this stream, you should consider contacting Perforce Technical Support first, as the obliterate command is complicated and has a number of options, and you want to make sure you use the right options. And take a checkpoint first, just for extra protection.
If you are using streams for temporary work, and frequently find yourself wishing to obliterate that work, consider using task streams.
And If you dont want any of the above, you can hide the deleted streams from the tree
To find a file in the depot or in your workspace:
1. Go to Search>Find File....
2. On the Find File tab, under Search in,enter the directory path you want to search.
3. You can drag and drop
the file path from the Depot or Workspace tree in the Tree pane.
4. Enter any of the following search criteria: Under Name matches any
of the following, select an operator (contains, is, starts with,
ends with) and enter all or part of the file name. You can add
multiple name match rows.
5. Under Submission date or changelist, enter a date, changelist, or
range of dates or changelists.
6. Unselect Include deleted depot files.
Click Find.
Hope that works for you , Good Luck !!
