A quick way to batch animations. 

Select all the .300 files and use CTRL+Right Click then select "Copy as Path" 

Highlight this part "D:\ now do CTRL+H for rename/replace. 

I renamed tool to ANM.exe for easier batching but in the replace window. Type in the name of the tool. Then leave a space. 

Now paste in the location of the folder you are about to batch. Dont forget to put a " before the folder location if it has a space.

Once location is pasted be sure to put a / on the end. Now go to the .216 file and copy its name. Place this info right after the forward slash. 

Don't forget to put a " at the end of the the .216 file!! Then leave a space. 

Last place in the original location next. Then hit "Replace All".  Final text should be how it is below.

Save the file as a "_.bat" so its at the very top of the folder. (Easier to find) 

As long as the data is typed correctly and files are in location. It will process all files and convert the. 

Open Blender and import the single .SMD. 

Now import .SMD again and highlight all .SMD files and then click "Import" 

Once complete all tracks will be imported into 1 mesh. Save file as .FBX.
