Prevent MetaData on file from Delete and Overwrite

[nranjith]

Using the exif tool , is it possible to prevent a meta-data on the file from being over-written or deleted ?

Hi Ranjith,

Do you mean overwritten by another application?

If so, the answer is no.  But you can use exiftool to save a copy of the metadata, then use this to restore anything that was changed or deleted.

Thanks Phil,

We were after having readonly meta-data on the File.  Considering that is not possible, I might have to consider saving copy of the metadata, then use Exif to restore anything that was changed or deleted. Could you point me in the direction of how to go about doing this, please?

There are many ways to do this, depending on what information you want to save and how you want to save it.  The MIE format is an exiftool-specific metadata container designed for uses like this.  See the MIE section of the Metadata Sidecar files documentation for details.
