Dimensions Preferences dialog box

Use the Preferences dialog box when you want to determine the method Dimensions CM uses to detect whether a file has changed. This setting takes effect for any files beneath the selected folder unless it is set differently for a subfolder.

Field	Description	Rules and Guidelines
Use modification time	Select this option if you want Dimensions CM to use the timestamp to detect whether the selected file, or the files in the selected folder, have changed when the file sizes are the same.
Checksum file content	Select this option if you want Dimensions CM to also use the file checksum to detect whether the selected file, or the files in the selected folder, have changed when the timestamps are the same.
Expand substitution variables	Select this option if you want item header substitution to be performed for the item file(s).	This option can also be set via the desktop client in the Tools \| Preferences dialog box.
Enable support for network folders	Select this option if you want to enable Dimensions CM Windows Explorer support for folders accessed via a network.	This option is disabled by default.
