What does this mean "%u"?

[sean0000]

Can someone explain what the %u behind the pcmanfm command does? Also what does the %f do following the leafpad command?

I have searched, but really don't know how to phrase my question.

Maybe point me to some documentation also?

Thanks,

Sean

edit: I just found the answer here:

Sorry for any trouble,

Not a problem. It is great when someone asks a question but continues to search for an answer rather than wait for someone else to provide it. Thank you .
