I found that using _ to replace / can cause some problems. Some people
tend to use the _ in the directory name. No problem in storing the data,
but during report you would want to convert the _ back again to / to be
able to display the correct path.

During some tests I found that relpacing / with __ (2x _) is very usefull.
Programs don't crash on this en people don't use a double _ in the directory

Oh, I was wondering, why include a type and name in the filename? With id and
dir you should be able to identify the quota you're storing? (or am i missing

Just my 2 euro cents.
