FileSystemEntry: remove() method
Deprecated
Avoid using this feature in new projects. This feature may be a candidate for removal from web standards or browsers.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The FileSystemEntry interface's method
remove() deletes the file
or directory from the file system. Directories must be empty before they can be
removed.
To recursively remove a directory as well as all of its contents and its
subdirectories, call FileSystemDirectoryEntry.removeRecursively()
instead.
Syntax
remove(successCallback)
remove(successCallback, errorCallback)
Parameters
successCallback-
A function which is called once the file has been successfully removed.
errorCallbackOptional-
An optional callback which is called if the attempt to remove the file fails.
Return value
None (undefined).
Exceptions
DOMException.INVALID_MODIFICATION_ERR-
The specified entry was the file system's root directory, or the specified entry is a directory which isn't empty.
DOMException.INVALID_STATE_ERR-
The file system's cached state is inconsistent with its state on disk, so the file could not be deleted for safety reasons.
DOMException.NO_MODIFICATION_ALLOWED_ERR-
The file system's state doesn't permit removing the file or directory.
DOMException.NOT_FOUND_ERR-
The file or directory doesn't exist.
DOMException.SECURITY_ERR-
The entry couldn't be removed due to permissions or other access constraints, or because there are too many calls being made on file resources.
