It's a business call rather than file size (as long as you have a 64-bit file system of course ;-)
64 bit files have a larger internal addressing structure so are theoretically marginally slower than equivalent 32-bit files and on a like-for-like basis they are larger for the same data volume held. I have never taken the time to measure the difference though (feel free to provide metrics anyone). It's also worth noting that the 64BIT flag in uvconfig does not enable or disable 64 bit files - it changes the default to 64 bit. I have seen this cause some confusion and (sometimes) large numbers of files on a system have been 64 bit as a result when file sizes don't warrant it. Distributed files allow you to sub-divide your data into separate compartments, and different groups of functional users may only be able to access specific distributed file elements, while others can access more....... Same program etc. Everyone accesses SALES but NORTH gets partfile 1, SOUTH gets partfile 2, THEBOSS sees all partfiles. They can also be used as a neat way of archiving data in bulk if the file keys and hashing algorithm are based on a relevant key (e.g. include Month and Year). That way you can offload specific files over (say) 1 year old and change the algorithm to "default" for partfiles of that number, Hope it helps..

Any issues you have with them? Do they impact system performance? Which would you prefer, a distributed file or a 64-Bit file to get around the 2 gig limit.
