4096 file limit on Windows XP

100 pts.
Microsoft Windows XP
Is there a registry fix or other options to increase this limit? Thanks in advance for the help!

Thanks. We'll let you know when a new response is added.

Windows XP it self doesn’t have a limit on the number of files per folder. It depends on the file system that you are using. The max files and folders per folder are:
FAT16 – 512
FAT32 – 65,534
NTFS – 4,294,967,295

If you use long file names for the files and folders (over 8 characters for the file name and 3 for the extension) then the number of files and folders available per folder will be reduced on the FAT16 and FAT32 file systems.

If you need to put more files and folders in a single folder you’ll need to convert the drive to NTFS.

    Ya, that might be the official math or office line from Uncle Bill but let me tell you, I have a pretty hefty machine but every time I get more than 50,000-60,000 files in a single directory thing start to go so slow it's not funny. I had one directory up to 195,450 files and just to view the directory with explorer took about 4-5 minutes. Than moving around in the directory cause a refresh that took almost al long. I notice a real change in performance about about the 40K files mark. I try not to let a single directory go above 20K files. IT took al morning jsut to get it to split the 195+K files into 10K files per folder. My performance came back to normal after I did it though. BTW: I'm talking about Win XP Pro SP3 HDDs are NTFS.

    It is better to add more RAM according to Microsoft.

    The post with the link mentioning adding RAM is to increase the file paging size limit. Is this the actual problem or it it something else.

    Multiple problems with the thread unfortunately. First, it's from 2008. Second, it's for Windows XP. Third, there is no "Windows XP limit of 4096 files" unless it refers to some installed program or app, in which case we might have a hard time finding out what "registry" key was involved.

    When it showed up a couple weeks ago, I had a hard time trying to understand why the "Answer" was about a "number of files per folder" and why the first comment was little more than a rant about managing files badly.

    The 'Answer' at the moment should be empty, and the only useful comment could be something like "What 4096 files limit?"
