It's LFN, as you can see from http://en.wikipedia.org/wiki/FAT32#Long_file_names[^].

Even though SFNs are supported for compatibility, I don't see any reason to use anything else but LFN. By apparent reasons, using both LFNs and SFNs can be very confusing.

thanx for sharing your information. Do you have any code which only uses LFN(long file name),bcoz in my code there is a mixture of both SFN and LFN. Thats why i want only LFN code for FAT32. If you have please send me the link.

You are welcome.
Well, I forgot SFN code long time ago. What link? To what? I have no idea. I don't develop file systems. And for applications, you just use files. There is no anything special in the code.

Anyway, I'll explain...

I don't really remember if I reported your post for abuse or not. But I usually look at the item thoroughly enough before reporting it. You cannot say it was reported for spam, just because there is no a separate "spam" category for abuse on the posts (there is only a report category "spammer" on the account record, and you don't want to be reported that way, as it can cancel your account). It's more likely that you've read some negative comment from me and then just drew your conclusions. Well, mistakes happen sometimes; maybe your post should not have been reported the way it was or should not have been reported at all. If this is the case, I apologize, but I don't really think this was the case. Here is why:

You see, the mere fact that your post was removed means that it was automatically removed due to a number of abuse reports of several members having sufficient privileges to affect such automatic decision. So, this was a collectively induced decision, not only mine, like in case of voting. And it's much less likely that several members all have done mistakes reporting your question post. Detail of each report don't matter much: it could be "not a question", "repost" or some other negative feedback. In all cases, chances are, there was something abusive in your question post, in one or other way.

I only can recommend to be quite careful and accurate when formulating any questions as separate question posts. Same goes about all other original posts, such as answers, articles, tips&tricks and so on. I will help you in getting help and will help the site to look better.
