I wish to create a flac tag giving the date that a music file was backed up to DVD so that I can later determine whether I have modified the file’s tags since it was last archived. Suppose I call this tag ARCHIVE_DATE. My hope is to create a column in the right-hand side of the MP3Tag interface window that indicates whether ARCHIVE_DATE is less than or greater than the file modification date. My first attempt didn’t work. I simply created a flac tag and entered a date in the format mm/dd/yy 0:00:00 PM, and defined a report column as “$if(%ARCHIVE_DATE%>%_file_mod_datetime%,x,)” This statement creates an “x” in the column no matter if the inequality is < or >. I suspect ARCHIVE_DATE must be defined as numeric in some way (like YEAR and TRACK).
As you can surmise, I don’t know what I’m doing. I’m simply mimicking examples. (A forum posting enabled me to create a column indicating whether a track has lyrics [$if(%lyrics%,x,) does the trick] and the definition of the Modifed column that is part of the standard MP3Tag configuration is %_file_mod_datetime%.
Incidentally, is %_file_mod_datetime% written into the file like the flac tags?
Any help would be greatly appreciated.
