Re: IMP/EXP accross platforms: What will be missing?

Unix-like operating systems usually do not need defragmentation software (as long as the filesystem won't be used in heavy write operations at a persistent high capacity level of over 90%). When issuing write operations, they try to find a chunk of free space that still accomodates data, while Windows for example chooses the first pieces it finds regardless of their size.

I remember the OS named RT/11 from Digital Equipment Corp. (decades ago). It never wrote a file in more than one chunk. With 8 Inch diskettes holding 360 KB max, that was hard.

The point is that it does play a role whether one or several files are written to harddisk at the same time, as long as fragmentation is concerned. After all, one can defragment a vfat partion (perhaps a NTFS one too) by just moving all files out and back, *one by one*.
