Advanced Batch File Processing:
| Create a batch file with the following line: |
| FOR /F %%a IN ('dir *.avi,*.mpg /b /s') DO frameshots "%%a" |
This basically calls FrameShots on every avi and mpg file found by the dir command. The option /b tells dir to output a 'bare listing' meaning only file names are displayed, no headers or sizes, etc. And the /s is optional, it searches through all subdirectories as well.

| |
| Make 5 thumbs from every avi file in the current directory: |
| FOR /F %%a IN ('dir *.avi /b') DO frameshots -thumbs 5 "%%a" |
