Hi Dan, We can use filepeek quite happily on our 64bit files. Do you mean uvfixfile? I know that has restrictions and cannot be used on 64bit files. The parameter in the uvconfig file is 64BIT. If this is set to 1, all files are created by default as 64bit files.

On a system with 32-bit addressing, the limit applied to all files, including backup images (at least to disk - I'm not certain about on tape drives, although I'd assume so). Now, we have 64-bit addressing, so the upper limit is in the pentabyte range. UniVerse and Unidata still have a default configuration parameter of 32-bit addressing. This parameter is easily changed to 64. Currently, the cost associated with going to 64-bit addressing for UniVerse & Unidata is the loss of a particular tool which is useful in repairing file corruption, filepeek. File corruption is pretty rare, but not unheard of, especially as hardware fails. By going to a scheme like RAID0+1 with transaction logging, you probably won't miss (watch the thread this starts...) filepeek. As an aside, reducing the amount of data in overflow reduces the risk of corruption, by minimizing the number of links, which are failure points. So you can enable U2 64-bit addressing in the (udt/uv)config file, which will then make the limit a historical curiosity. Or you can use dynamic files (although at the most - with a lot of luck - this gives you 4Gb), or in UniVerse you can use distributed files, which imho are a better choice anyway, making the size of a file limited only by your disk drive budget.
