Be VERY careful with LFN support and 8.3 filenames. MS' implementation of LFN support is broken by design, because the short filenames are not saved along with the long ones and instead are autogenerated from the long ones -- which, if you have a set of similarly named files with long filenames can easily result in a 8.3 filename referring to a different file after you delete and copy. See the section "Ambiguous LFNs" here: http://users.iafrica.com/c/cq/cquirke/lfns.htm The upshot is, you're best off avoiding these older 8.3 FAT file systems altogether.
