No, as files does not have row names.  But data frames do, so perhaps

DF[sort.list(row.names(DF)), ]

is what you are looking for.

I presume you mean a data frame rather than a file.  In which case the 
answer is yes:

df <- data.frame(a=1:10, b=rnorm(10), row.names=sample(letters[1:10]))
df[order(rownames(df)),]
