Hi,

We are planning for Data conversion. We will be moving files from Unix to
windows. I just want to know what is the maximum text file size allowed in
windows 2k advanced server.

Thank you

From the resource kit;

Table 3.10 FAT16 Size Limits

Description Limit
Maximum file size 2^32 - 1 bytes
Maximum volume size 4 GB
Files per volume 2^16


Maximum Sizes on FAT32 Volumes
The FAT32 volume must have at least 65,527 clusters. The maximum number of
clusters on a FAT32 volume is 4,177,918. Windows 2000 creates volumes up to
32 GB, but you can use larger volumes created by other operating systems
such as Windows 98. Table 3.11 lists FAT32 size limits.

Table 3.11 FAT32 Size Limits

Description Limit
Maximum file size 2^32 - 1 bytes
Maximum volume size 32 GB (This is due to the Windows 2000 format utility.
The maximum volume size that Windows 98 can create is 127.53 GB).
Files per volume Approximately 4 million



Important

Windows 2000 can format new FAT32 volumes up to 32 GB in size but can mount
larger volumes (for example, up to 127.53 GB and 4,177,918 clusters from a
volume formatted with the limits of Windows 98). It is possible to mount
volumes that exceed these limits, but doing so has not been tested and is
not recommended.

Maximum Sizes on NTFS Volumes
In theory, the maximum NTFS volume size is 2^32 clusters. However, even if
there were hardware available to supply a logical volume of that capacity,
there are other limitations to the maximum size of a volume.

One of these limitations is partition tables. By industry standards,
partition tables are limited to 2^32 sectors. Sector size, another
limitation, is a function of hardware and industry standards, and is
typically 512 bytes. While sector sizes might increase in the future, the
current size puts a limit on a single volume of 2 terabytes (2^32 * 512
bytes, or 241 bytes).

For now, 2 terabytes should be considered the practical limit for both
physical and logical volumes using NTFS.

The maximum number of files on an NTFS volume is 2^32 - 1. Table 3.12 lists
NTFS size limits.

Table 3.12 NTFS Size Limits

Description Limit
Maximum file size 264 bytes - 1 KB (On disk format)
244 bytes - 64 KB (Implementation)

Maximum volume size 264 allocation units (On disk format)
2^32 allocation units (Implementation)

Files per volume 2^32 - 1
