windows limit on no of files in a particular folder -

-

i in doubt whether right place question.. want know if windows 7 or xp has limit on no. of files within particular folder?

there's no practical limit on combined sizes of files in folder, though there may limits on number of files in folder. more importantly, there limits on individual file size depend on filesystem you're using on hard disk. (the "filesystem" nothing more specification of how files store on disk.)

let's break down file system:

fat aka fat16

fat, file allocation table, successor original fat12 filesystem shipped ms-dos many, many years ago.

  • maximum disk size: 4 gigabytes
  • maximum file size: 4 gigabytes
  • maximum number of files on disk: 65,517
  • maximum number of files in single folder: 512 (if recall correctly, root folder "/" had lower limit of 128).

fat32

"there's no practical limit on combined sizes of files in folder, though there may limits on number of files in folder."fat32 introduced overcome of limitations of fat16.

  • maximum disk size: 2 terabytes
  • maximum file size: 4 gigabytes
  • maximum number of files on disk: 268,435,437
  • maximum number of files in single folder: 65,534

ntfs

ntfs, or "new technology file system" introduced windows nt, redesigned file system.

  • maximum disk size: 256 terabytes
  • maximum file size: 256 terabytes
  • maximum number of files on disk: 4,294,967,295
  • maximum number of files in single folder: 4,294,967,295

note when "disk" above, i'm talking "logical" disks, not physical. no 1 makes 256 terabyte disk drive, using ntfs can treat array of disk drives single logical disk. presumably if have enough of them, can build huge logical drive.

also note ntfs's 256 terabyte limitation may implementation restriction - i've read ntfs format can support disks 16 exabytes (16 times 1,152,921,504,606,846,976 bytes).
