download accelerator and flashfxp

[mehtag]

i'm using win2k server and ffxp 2.0 rc3 build 875

this question is a bit off topic but plz help
there are many ftp sites of the type like "ftp://xxx.xxx.xxx.xxx/ /tagged /_viti/ incoming/" like there are
spaces in between.
when i try to download a file using dap or flashget they dont work
but ffxp picks them up .
what kind of naming conventions this sites use in their links??
plz guide
