merging ARL file from WRF on PC

[maiacalvelloWRF]

Hello! I used GUI interface on my PC to convert WRF NECDF files to ARL. Each ARL file is related to one hour data. If I use multiple ARL one hour data I found the WARNING: "Only one time period of meteo data".
Now I would like to try in merging the one time period files into one file but I don't know how to do in Windows.
Did anyone try to make this merging on a PC? Do you have any suggestion?

The file_merge program included in your HYSPLIT installation may be used to combine two ARL-formatted meteorological files. The program is located in the exec directory where HYSPLIT is installed, for example, C:\hysplit\exec. Please refer to https://www.ready.noaa.gov/hysplitusers ... file_merge for a brief description on how to use the program.
