Soil data for CFSR Vtable

Hello,
I'm looking at the middle lines of Vtable.CFSR
144 | 112 | 0 | 10 | SM000010 | fraction| Soil Moist 0-10 cm below grn layer (Up) | 2 | 0 | 192 | 106 |
144 | 112 | 10 | 40 | SM010040 | fraction| Soil Moist 10-40 cm below grn layer | 2 | 0 | 192 | 106 |
144 | 112 | 40 | 100 | SM040100 | fraction| Soil Moist 40-100 cm below grn layer | 2 | 0 | 192 | 106 |
144 | 112 | 100 | 200 | SM100200 | fraction| Soil Moist 100-200 cm below gr layer | 2 | 0 | 192 | 106 |
11 | 112 | 0 | 10 | ST000010 | K | T 0-10 cm below ground layer (Upper) | 0 | 0 | 0 | 106 |
11 | 112 | 10 | 40 | ST010040 | K | T 10-40 cm below ground layer (Upper) | 0 | 0 | 0 | 106 |
11 | 112 | 40 | 100 | ST040100 | K | T 40-100 cm below ground layer (Upper) | 0 | 0 | 0 | 106 |
11 | 112 | 100 | 200 | ST100200 | K | T 100-200 cm below ground layer (Bottom)| 0 | 0 | 0 | 106 |
This looks fine (4 levels of soil) but the problem is that the soil data don't seem to be included in the regular netCDF files but in separate files (e.g. sfcf2025012912.01.2025012912 for January 29 of last year). However, METGRID doesn't recognize their format and generates the error message:
ERROR: Didn't recognize format version of data in sfcf:2025-01-29_12.\nFound version 1195791136 but expected either 3, 4, or 5. This could be an endian problem.

Is METGRID expecting these files? Should they be reformatted or is there any other solution?
Thanks.

The files don't have any extension (unlike flxf...grb2 which I was able to ungrib without any trouble) so that explains why I was trying to process them directly with METGRID. I reached out to the CFS Team asking them a couple of questions a while ago but (until they answer) the only option is to figure things out (I was hoping that maybe someone was familiar with the files/format).
 
I agree that we need to first figure out the format of the data, before we can move on to process it. Please keep me updated if you get any feedback from NOAA.
