need a simple script to copy a file to Pocket PC

I'm a novice at this and need some help copying a file on a PC (lets call it 'abc.pda') to replace an existing file on a Pocekt PC in 'Program Files/abc'

I don't want a full-blown installer, but just want to replace one of the files('abc.pda') in the folder.

I tried the copy file to PDA on the NSIS site, but had no luck ( I am sure a lot that is commented out needs to be used)

Any help would be appreciated.

Have you tried one of the available solutions?
