exists(path, stat=False, base=None, **kwargs)#

Returns True when the path exists and False otherwise. When stat is True, returns the stat object or None.

stat(path, base=None, **kwargs)#

Returns a stat object or raises an exception when path does not exist.

isdir(path, stat=None, base=None, **kwargs)#

Returns True when path refers to an existing directory, optionally using a precomputed stat object instead, and False otherwise.

isfile(path, stat=None, base=None, **kwargs)#

Returns True when path refers to a existing file, optionally using a precomputed stat object instead, and False otherwise.

chmod(path, perm, base=None, silent=False, **kwargs)#

Changes the permission of a path to perm. Raises an exception when path does not exist or returns False when silent is True, and returns True on success.

Removes a file at path. Raises an exception when path does not exist or returns False when silent is True, and returns True on success.

rmdir(path, base=None, silent=True, **kwargs)#

Removes a directory at path. Raises an exception when path does not exist or returns False when silent is True, and returns True on success.

remove(path, base=None, silent=True, **kwargs)#

Recursive removal is potentially expensive in terms of remote file operations, so this method is designed to reduce them as much as possible.

mkdir(path, perm, base=None, silent=True, **kwargs)#

Creates a directory at path with permissions perm. Raises an exception when path already exists or returns False when silent is True, and returns True on success.

mkdir_rec(path, perm, base=None, silent=True, **kwargs)#

Recursively creates a directory and intermediate missing directories at path with permissions perm. Raises an exception when path already exists or returns False when silent is True, and returns True on success.

listdir(path, base=None, **kwargs)#

Returns a list of elements in and relative to path.

filecopy(src, dst, base=None, **kwargs)#
