Working Directory - Microtek ScanMaker 6100 Pro User Manual

If "Quality" option is selected, the scanning carriage slows down
while the CCD is exposed to the light source. As a result, a better
image is achieved. Most scan materials can get a quality scan if this
mode is chosen.
Best Quality:
This option is available for 10- or 12-bit scanners only. The CCD
exposure scheme is much the same as the "Quality" option, but
image correction is first applied to the 10- or 12-bit image, then the
image is converted to 8-bits. RGB Colors (48-bit) image is always
scanned in Best Quality option regardless of the option selected.
This option is useful for scanning originals of lower quality and for
performing image correction without losing detailed information.
Note: This option is useful for scanning Line art images to keep
edges smooth; e.g., edges of a logo.

Working Directory

This lets you specify a place to store temporary working files (e.g.,
scan job files) during a scanning session. If the directory you
specify is not found or does not exist, a warning message appears,
and ScanWizard 5 will create one automatically for you.
If the computer is shared by several users, each user may specify a
particular working directory to use..
Memory Usage
(for Macintosh only)
This option controls the way ScanWizard 5 uses memory. Three
options are provided:
Auto:
This is the default setting. ScanWizard 5 maximizes memory usage
from both system and application, looking for memory first from the
system heap and then from the application heap.
Application:
ScanWizard 5 will only use the memory inside the application heap
