LOVD supports importing custom columns from tab delimited text files, generated by the download custom columns feature available in the setup area. We do not recommend you to edit this file.
The first line should contain the version number and data type definition. If you do not include this line, LOVD will not accept your file. The line should say something like:
### LOVD-version 2000-150 ### Columns ### Do not remove this line! ###
LOVD will only import the custom columns from the file which are not already in the system. No comparison is performed between the columns already in LOVD and the columns in the file, LOVD just checks if the column IDs are present in the database or not.
This feature was added in LOVD 2.0-15, released 2009-02-03.
