Abstract
A method of preserving file metadata associated with an edited file, performed on a client device, includes storing in a log information denoting a plurality of create, delete, and rename operations on one or more files in a file system, and determining when two or more operations denoted in the log, including an operation involving a first file and another operation involving a second file, comprise an atomic save of a respective file, the first file comprising a first version of the respective file, and the second file comprising a second version of the respective file, the first file and second file each having associated metadata. The method further includes associating a subset of the metadata of the first file with the second file, such that at least one of a globally unique file identifier and file access permissions associated with the first file become associated with the second file.
