This question already has an answer here:

I am running Windows XP Professional, service pack 3. Right now I have 4,398 files in a single folder, and Windows XP seems to read it fine. How many more files can I place in this same folder, either theoretically or practically? Thanks for your time.

This answer is taken from one of the sister sites at StackOverflow and is copied here for your convenience.


  • Maximum number of files: 268,435,437
  • Maximum file size: 4GB
  • Maximum number of files per directory: up to 65535, or less depending on file names


  • Maximum number of files: 4,294,967,295
  • Maximum file size: 16TB currently (16EB theoretically)

FAT32 has a limit of 65535 files per directory. As for non-FAT32, I could not find a "hard limit", but the information in this comparison chart is quite informative.

Your exercise in copy-and-paste resulted in loss of information (e.g., which 'comparison chart'?). – Andreas Rejbrand Jun 29 '13 at 17:13
Thanks! I am using NTFS. It looks like I don't have to worry about exceeding the limit! :-) – Andrew Jun 29 '13 at 17:22
