Drive Space

These options provide control over what appears within the drive space docking panel, as well as the computer view.

Drive Types

Fixed drives - These include local hard drives. Recommended.
Removable drives - Usually consists of thumb drives, etc.
CDROM drives - CDROM, CDRW, DVD, etc.
Remote (network) drives - Includes any mapped network drives. Note that this can slow application performance slightly on slower networks (and is therefore not recommended for use within a wireless network environment).
RAM disk drives - Any type of memory-based drive.
Unknown drive types - Anything else not otherwise categorized. Not recommended.

Ignore these drive letters - Allows for specification of drives that should not be included (floppy drives, for example) in the drive space panel. Separate multiple drive letters with semi-colons.
Automatically refresh every X seconds - Specifies how frequently the drive space panel should automatically refresh itself.
Ignore storage devices that are offline - When this switch is engaged, FolderSizes will ignore any drive that it cannot successfully query for size information.
Max history entries per volume - Controls the maximum number of historical disk space entries stored per volume.
Calculate growth % from - Configures the period of time over which disk space historical growth is calculated.
