Check out this filename:
J:\Traffic\Ross\US 35\US 35-Larrick's Lane Interchange Justification Study\Signal Warrants\US 35 WB off ramp (prop)-Egypt Pk & PV Rd signal warrant analysis\COUNT-PV Rd WB West of Warden's(used to project traffic on East leg of new intersection).pdf
It is 249 characters long. Now where it's at, it's not a problem. J: is just one directory on the root of a server drive. But something weird happens if the user moves this file to his W: drive (which is 4 directories from the root on another drive, making the total drive:\path\filename some 280 characters). He can see it, edit it, copy it, move it, etc. from his workstation, but if you go to the server console, you cannot find this file! Nor does it get backed up! No error messages enther. I told them, 190 characters max.
I've made a pretty good dent in the duplicates, but it's been literally weeks of work. We went from over 450,000 duplicate files to just under 200,000. Most of these were mistakes in creation of directory structure, and the mistake wasn't removed, to one case where a user was flat out paranoid and copied everything... twice. Mostly small files though, as the removal only cleared about 60 gig.
As to what I'm using. an old PC mag utility Dupeless. But it takes forever to run, I started another run at about 8:15 a.m. and it's still running at 2:12 p.m. :(
