optimizeStorage

Optimizes storage usage, i.e. deletes some files and returns new storage usage statistics.
Secret thumbnails can't be deleted.

optimizeStorage(size, ttl, count, immunity_delay, file_type, chat_ids, exclude_chat_ids, chat_limit, callback, data)

Field	Type	Description
size	int53	Limit on the total size of files after deletion. Pass -1 to use the default limit.
ttl	int32	Limit on the time that has passed since the last time a file was accessed (or creation time for some filesystems). Pass -1 to use the default limit.
count	int32	Limit on the total count of files after deletion. Pass -1 to use the default limit.
immunity_delay	int32	The amount of time after the creation of a file during which it can't be deleted, in seconds. Pass -1 to use the default value.
file_types	vector	If not empty, only files with the given type(s) are considered. By default, all types except thumbnails, profile photos, stickers and wallpapers are deleted.
chat_ids	vector	If not empty, only files from the given chats are considered. Use 0 as chat identifier to delete files not belonging to any chat (e.g., profile photos).
exclude_chat_ids	vector	If not empty, files from the given chats are excluded. Use 0 as chat identifier to exclude all files not belonging to any chat (e.g., profile photos).
chat_limit	int32	Same as in getStorageStatistics. Affects only returned statistics.
