Abstract

A method for removing some or all metadata from files during copying or moving. Metadata management software may register with an operating system and be called to remove metadata crossing a trust boundary, such as going from a local hard drive to a file share.

Claims

1. A method of removing metadata from a file with metadata comprising:

reading a value from an input file;

determining if the value is part of the metadata to be removed;

replacing the value with a placeholder; and

writing the value to an output file.

2. The method of removing metadata from a file with metadata of claim 1 in which the output file is the same file as the input file.

3. The method of removing metadata from a file with metadata of claim 1 in which the placeholder is a string of spaces.
