There appears to be no way to group files with a circle-X icon, indicating an error in the file metadata, separately from others so that they can be located and fixed. A pseudo tag containing the same error message that is displayed in the title of the Metadata dialog box would allow these files to be grouped with a sort on that tag.
You can filter for these files with
%_tag_read% HAS Error
If you create a column with
Value: %_tag_read%
you can sort by the contents of that column.
Got it! It took a number of tries because I couldn't find documentation on string literals or $strstr return value (0 means "not found"), but finally it worked with "$ifgreater($strstr(%_tag_read%,ERROR),0,%_tag_read%,)"
Thanks!
And where do you use
see
Put the expression in the "Value" field of a new column (I labeled the column "Error.")
OK, now I see: "This implies that you can enclose parameters in ' to pass them as raw text without parsing." You can't specify an empty string that way, however.
Isn't this very complicated and simply
Value: %_tag_read%
would produce the same result and you can sort by the text.
If you want to locate such files, wouldn't the filter do that as it limits the displayed the files to just those with a displayed "Error"?
