What's max. no. of files on root-dir under XP Pro?

[Happy Hopping]

Remember in good old win 98SE, you can only have something like 128 or 256 or was it 512 files under the root-dir. Any more than that you need sub-dir to insert those files from root-dir.

Does Win XP Pro still have that limitation? IF so, what is the max. no. of files you can have at your root-dir on a DVD+R. I don't want to create a sub-directionary folder to dump those files in there.

On hard disks, NTFS either removed the limitation, or made the limit so insanely high that it was a non-issue.

As for CD's and DVD's, they conform to different standards and use another type of file system, so I have no clue what limitations they might have :p

[tesfaye]

Heheh, I read the title and not the whole post. oops! DVD+R? You will need to read up on the various file systems available for DVD media recording.



The limit is 4,294,967,295 files. You would need a 2TB drive formatted with 512byte allocation units (clusters) to hit that limit if you are even allowed to format a volume that large with 512b clusters.

So until you are in that situation and I think only one or two members of this forum have been crazy enough so far to create storage systems of that magnitude, you will be limited by the amount of available allocation units. Only one file can occupy an allocation unit at a time but a file can span multiple allocation units if needed. So an 80 gig drive formatted with allocation units 4096 bytes in size would yield 19520983 allocation units. So if each file were less than or equal to 4096 you could have about 19520983 files.

MS has whitepapers on all this stuff or you can check out the Wiki here: http://en.wikipedia.org/wiki/NTFS.

Maybe later I'll write a script to generate files and see what happens when you max out the allocation units in the ROOT of a drive. :) I'm curious about this. I was always told to stick my files in folders and stay the f*ck out of the root of volumes.

Why wouldn't you want to use a folder?

Just curious.

With 750GB drives on the market now, it's not going to take much to make a a 2TB porn server...

[tesfaye]

750GB available now? Wow, that's awesome! What's the form factor on those things? Is it still 3.5inch?

If you store media files you will probably go for 32KB clusters. The NTFS limit wont be reached anytime soon at that size.

Damn, 750GB drives, I want a few in my machine just so I can say I have them.

Now we need 100mb broardband :D

So I can access the files from the root dir w/o changing to sub-dir every time

.

You mean if I burn a DVD+R, it allows me to fit 4,294,967,295 files in the root directory? We are talking about a root-directory, not inside a sub-directory. Serious? So Win XP Pro removes the root-dir limitation from 512 or whatever that no. was?

Ok Happy Hopping Lazy Searcher check this link:
http://homepage.mac.com/wenguangwang/myhome/udf.html

Now start searching for info on ISO 9660, Joliet and UDF. Those are the formats that you would use to burn a DVD.

:D

KeithFIOS is coming to my area (Staten Island) with up to 50Mbps for the top o' da line package. I believe 15Mbps will be $39 a month. 50Mbps is like $149.

But you're going to have to change to the optical drive every time any way.
So, what's the difference between....

D:\XXX.jpg

and

D:\a\XXX.jpg

2 characters?????


seems like a non-issue to me, but whatever floats your boat.

Ok only because I want to get my post count up (got a problem with that?), why don't you open up your burning program, create a disc and do a test burn. It will give you all of the warnings about file sizes, file names, directory structure issues etc without ever actually writing to disc. Well, at least Nero has that feature.

If you don't mind my asking, what are you trying to accomplish?

[Happy Hopping]

NTFS doesn't have a 511 root entry limit like FAT file systems did.

thanks, that's what I was really asking.

[Happy Hopping]

thanks for the link. I'll read it tomorrow. I need to backup a lot of very large size files, and if there is no need to create sub-dir, as these files are very large, it doesn't take long to fill up a 4.7GB DVD+R, so I figure if I don't need to create sub-dir, it will save me time to change dir to the sub-dir each time I need to read them, as DVD+R access speed is slow.
