NTFS or FAT32?

What really is the difference? File encryption,etc. Speed differences. Windows XP was pre-installed on my new computer, how do I know which style I have?
You probably have NTFS. To check, you can always go to "My Computer," right-click on your hard drive, and hit "Properties." It'll say right there.

I checked...it is FAT 32. Is one better than the other and why?
How large is your hard drive? If it is rather large and in just one partition, you are probably having huge cluster inefficiency. A 40 GB hard drive, which is pretty standard now, has a 32 K cluster size. That means that if you had a file that was 1 byte, it would really be taking up a full 32 K, since every file takes up a cluster. Compare that to NTFS, which has 4 K cluster sizes by default. Your hard drive, essentially, will get filled up very easily. To see your cluster size, go to the command prompt (cmd.exe) and type 'chkdsk.' It will tell you your cluster size.

FAT32 also was not made for drives this large (when FAT32 was released with Windows 98, most hard drives were about 10 GB at largest), and has severe performance degradation the more stuff you put on your hard drive. NTFS does not have this problem and runs fast no matter how much you put on it. Just remember to do regular Disk Defragment, because it can be slowed down that way.

Plus, if you are interested in more of the technicals, NTFS supports file compression, file encryption, additional file attributes to prevent unauthorized users, etc. I'm really not using any of this right now, since I'm the only user on my computer and I'm not hooked up to a broadband network, so, honestly, I really just use it for increased speed and cluster efficiency.

BTW, you can change your FAT32 to a NTFS drive using the 'convert' command in the command prompt. I suggest a 'convert /v' because I always like to read the detailed messages. Once you do that, however, there is no way to convert back to FAT32. You would have to reformat your hard drive. Basically, always go into something knowing what you're doing.

Thank you for an indepth answer Melon, good info. It is a 40 gig...I think I might wait until I get a little more info or advice before I convert to NTFS. Or at least be a little more comfortable with the idea. I don't want to goof anything up or do something I can't undo without reformatting.:cool:
I would suggest going to NTFS... even if it means reformatting

my pc sped up ALOT after converting :D
OK...I have just about decided to do it. Before I do, what exactly do I need to do to convert...don't want to goof it up:eek:
In the run box, type in 'command' or 'cmd' and hit enter, in the command window that opens, type in 'convert x: /fs:ntfs.' 'x' being the drive/partition you want to convert. To convert a drive from ntfs to fat32 you'll need third party software such as PowerQuest's Partition Magic.

There are some really good articles that you should should read before converting your drive(s):

Got it done, thanks for all the info and help... it was painless:cool:
conversion problem

I converted but I have a problem. After conversion, when I do disk cleanup it stalls and never finishes. Stops on "compress old files". Under windows task manager it shows 100% cpu usage. Everything then slows down. I then have to do an "end process" to stop it. I reinstalled winxp but no help.

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?

Impressed you have kept this alive this long EP! So many sites have come and gone. :(

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
