Yes it is, the file names are always 11 digits

The file name is based on the date the "package" was issued. then the "-" is the number of times it has been inspected.

So the filenames are "package issued date" & "inspection number"

This and the file location was not designed by me, and I personally don't like the arrangement, this is how its been done historically, and I'm trying to work with what I got.
