Windows 7: xfat32/fat32/NTFS

When you save a file from your program to the HHD/SSD on the NTFS disk and then later transfer it to a disk that is formatted for xfat32/fat32 does it affect the program/saved information in anyway to be read back into the program?

No, if I understand the question.

You can move a file back and forth between a FAT32 partition and a NTFS partition.

Think of a game of checkers.

The checkers don't care whether you are using a fancy ivory checkerboard or a 99 cent cardboard checkerboard. Not an exact analogy, but you get the point.

Okay thanks for the reply and yes I understand that. Now if I can get about the restore/backup and the other question, I'll be a gru (LOL).

There is one little condition. The file blocks must not be bigger than 4GB-1. E.g. imaging programs write such files and Windows data backup does too.

The FAT32 is a file system on which a max file size of 4 Gigabyte can be stored.

exFAT is a new file system on which a max file size of 16 Exabyte can be stored. Currently this file system is used only for Flash drives and not for HDDs.

The above file systems have no built in file permissions ( except for the basic file attributes like, system, hidden, read only and archive).

NTFS is a robust file system with built in file permissions to make the files either accessible or inaccessible to other users. This is an industry standard file system from Microsoft and is widely used by windows OSs like Win NT, Win 2000, Win XP, Win Vista and Win 7. This file system can store a single file of max 16 Exabyte.

The link below explains the differences between exFAT, FAT32 and NTFS.

exFAT Versus FAT32 Versus NTFS and NTFS vs FAT

When a file from NTFS file system is copied to either FAT32 or exFAT, the full contents of the file are copied, except the streams data and the NTFS permissions.

So for the application which has created the file it does not make any difference, whether the file is read from NTFS partition or FAT/exFAT partition.

It won't affect the program information or data saved, but it will affect the permissions on the file. As stated above, moving a file from NTFS (permissions-based filesystem) to FAT (no file permissions) it will strip the NTFS permissions. When you transfer this file back to NTFS, it will no longer have the permissions it left with. This may or may not affect what you're doing.
