I thought of that and wish now I had mentioned it in my writeup. There is no chance of a name collision in that example since the year, month and day are repeated in the new name. For example:

8_2007_10_22_15_34_23_Table_-_20071022_XYZ_W3.pdf
8_2007_9_22_15_34_23_Table_-_2007922_XYZ_W3.pdf

[download]

The new filenames for these two will be:

Table_-_20071022_XYZ_W3.pdf
Table_-_2007922_XYZ_W3.pdf

[download]

Having the sorting correct only matters among the filenames that start with the same YYYY?MDD dates. The HH_mm_ss format seems to be consistent and therefore sortable with the default sort. I'm assuming that from the limited example data we were given.
