Scan for corrupt metadata

[warrencalvert]

Hi,

I see there's a command that will repair corrupt metadata by (#20 in the FAQ).  However, is there a way to scan all files in folders recursively to get a list of photos that have corrupt metadata?
I'd like to get some idea of how widespread the corrupt metadata is before running a repair.

I guess the next question would be, is it possible to repair corrupt metadata only on files that have corrupt metadata?  I.e. files that are fine I would rather not touch.

Thanks,
Warren.

Hi Warren,

It depends on what you call "fine".  Try this:

exiftool -validate -warning -a FILE

Then you could rebuild files that contain warnings, but it isn't guaranteed that all warnings would go away (ExifTool doesn't repair everything).

And some of the results may be things you don't want to "fix".  For example
Warning                         : [minor] IPTC Sub-location too long (35 bytes; should be 32 max)

The spec says IPTC:Sub-location should be no more than 32 characters, but this is ignored by nearly every program.  "Fixing" this will truncate the data.
