+	"""Import file from the given path
+
+	Some conditions decide if a file should be imported or not.
+	Evaluation takes place in the order they are mentioned below.
+
+	- Check if `force` is true. Import the file. If not, move ahead.
+	- Get `db_modified_timestamp`(value of the modified field in the database for the file).
+		If the return is `none,` this file doesn't exist in the DB, so Import the file. If not, move ahead.
+	- Check if there is a hash in DB for that file. If there is, Calculate the Hash of the file to import and compare it with the one in DB if they are not equal.
+		Import the file. If Hash doesn't exist, move ahead.
+	- Check if `db_modified_timestamp` is older than the timestamp in the file; if it is, we import the file.
+
+	If timestamp comparison happens for doctypes, that means the Hash for it doesn't exist.
+	So, even if the timestamp is newer on DB (When comparing timestamps), we import the file and add the calculated Hash to the DB.
+	So in the subsequent imports, we can use hashes to compare. As a precautionary measure, the timestamp is updated to the current time as well.
+
+	Args:
+		path (str): Path to the file.
+		force (bool, optional): Load the file without checking any conditions. Defaults to False.
+		data_import (bool, optional): [description]. Defaults to False.
+		pre_process ([type], optional): Any preprocesing that may need to take place on the doc. Defaults to None.
+		ignore_version (bool, optional): ignore current version. Defaults to None.
+		reset_permissions (bool, optional): reset permissions for the file. Defaults to False.
+
+	Returns:
+		[bool]: True if import takes place. False if it wasn't imported.
