This page describes how to remove a label on a single Google Drive file.
To remove the file label metadata from a file, use the files.modifyLabels
method. The request body
contains an instance of ModifyLabelsRequest
to modify the set of labels on a file. The request might contain several
modifications that are applied atomically. That is, if any modifications aren't
valid, then the entire update is unsuccessful and none of the (potentially
dependent) changes are applied.
The ModifyLabelsRequest
contains an instance of LabelModification
which is a modification to a label on a file. It might also contain an instance
of FieldModification
which is a modification to a label's field. To remove the label from the file,
set FieldModification.removeLabel
to True
.
If successful, the response
body
contains
the labels added or updated by the request. These exist within a modifiedLabels
object of type Label
.
Example
The following code sample shows how to use the labelId
to remove all fields
associated with the label using the fileId
. For example, if a label contains
both text and user fields, removing a label deletes both
the text and user
fields associated with the label. Whereas, unsetting the text field removes it
from the label but leaves the user field untouched. For more information, see Unset a label field on a file
.

Replace the following:
- LABEL_ID
: The
labelId
of the label to modify. To locate the labels on a file, use thefiles.listLabels
method. - FILE_ID
: The
fileId
of the file for which the labels are modified.
