SmartStor Jukeman Files Occupy Twice the Space on an NTFS Partition

ID: Q243411

The information in this article applies to:

Microsoft Windows NT Server versions 3.51, 4.0
Microsoft Windows NT Workstation versions 3.51, 4.0

SYMPTOMS

A SmartStor Jukeman file may occupy twice the amount of drive space that is required for the file after the file is copied or moved on an NTFS partition. The file's properties list the correct amount of space, but the file uses twice that amount of space on the hard disk.

CAUSE

This behavior is caused by a problem in SmartStor Jukeman version 2.3.

RESOLUTION

To resolve this issue, upgrade to SmartStor Jukeman version 2.4.1 or later.

To work around this problem, copy the file to a FAT partition and then back to the NTFS partition. When you copy the file to a FAT partition, you remove the data stream that causes the file to occupy twice the required space (because NTFS partitions support data streams but FAT partitions do not).
