The most common archiving action is to move a project tree to another file, the archive file.
Archive the subtree starting at point position to the location
Check if any direct children of the current headline could be moved to the archive. To do this, check each subtree for open TODO entries. If none is found, the command offers to move it to the archive location. If point is not on a headline when this command is invoked, check level 1 trees.
As above, but check subtree for timestamps instead of TODO entries. The command offers to archive the subtree if it does contain a timestamp, and that timestamp is in the past.
The default archive location is a file in the same directory as the
current file, with the name derived by appending ‘_archive’ to the
current file name. You can also choose what heading to file archived
items under, with the possibility to add them to a datetree in a file.
For information and examples on how to specify the file and the
heading, see the documentation string of the variable
There is also an in-buffer option for setting this variable, for example:
If you would like to have a special archive location for a single entry or a (sub)tree, give the entry an ‘ARCHIVE’ property with the location as the value (see Properties and Columns).
When a subtree is moved, it receives a number of special properties
that record context information like the file from where the entry
came, its outline path the archiving time etc. Configure the variable
org-archive-save-context-info to adjust the amount of information
