Assorted ?s

I have looked but haven't found much.

Are there any references to the logic used in Disk Defragmentation ?

I was also wondering about the O.S.

Say a 5 meg file is deleted.

If another file less than 5 megs is added, is it "put" in the hole left by the
file deletion ?

How does a registry restoration via a registry backup compare to a disk image restore ?

I ask because it's difficult to restore files/config info to their original state when doing a disk image restore.

Andy,

The later NTFS is a tree structure rather than a hash table structure and it is a lot less sensitive to disk fragmentation that the older FAT system. For what it was worth a properly defragmented FAT32 system was noticably faster than NTFS but Microsoft effectively phased it out from about Win2000 onwards in favour of their NTFS system.

Thanks, found some info here.

Based on what's here, I switched to UltraDefrag.
It's faster than the others that I have tried.

i tested a few programs a while back
the one i finally decided on was Puran Defrag

http://www.puransoftware.com/Puran-Defrag-Download.html

on that page, they have a "trial" version and a "free" version - you want the free one   :U

as for your question about the deleted file, it is likely that windows will try not to overwrite that file "for a while"
"for a while" means "some unknown period" (until it needs the space or defrags)
it is hard to know when that will be - lol
but, some effort is made to retain the old stuff

Another nice tool :

WinContig : The free file defragmentation tool

that one does look nice, Erol
the thing i liked about Puran was the configuration flexibility.....


it looks like WinContig has much the same stuff

There is also this one:

But  I don't know which is the best.
