System information
Item Description
Temporary  files folder Displays the folder where temporary  files are created. Click the 
Browse button to specify a new folder.
When you add a media file from a removable  device, a copy of 
the media file is stored in a subfolder within this  folder. This 
keeps the media file available for use even if the source  of the 
media is no longer accessible.
Be  aware that these subfolders are cleared when you close the Vegas 
Pro  application. However, they are not cleared if the application 
closes inappropriately.
Free storage space  in 
selected folder
Displays  the amount of space available in the folder specified in the 
Temporary files folder box.
Default All Restores the General page options to  the default settings.

adjust the preview  settings for the Video  Preview window. For more information, see "Using the Video 
Preview Window" on page 465.
Item Description
Dynamic RAM preview 
max
Enter a value to set the amount of RAM  that you want to dedicate  to 
video previews. For more information, see "Using Dynamic RAM 
Previews" on page 473.
The maximum size of  the RAM cache is displayed to the right of 
the control. You must leave  at least 64 megabytes available for 
Vegas Pro  (more if you are creating complex projects). If you 
reserve excessive  amounts of RAM for your RAM cache, 
performance may decrease.
Maximum  number of 
rendering threads
This setting specifies the  maximum number of threads that will be 
used for rendering  files.
Increasing the setting will  not increase performance beyond the 
number of available threads; for example,  if you have a single-
processor computer, choosing 2  will not improve rendering 
performance.
Decrease the setting if you  have a multiprocessor (or multicore) 
computer and want to limit processor  use or turn off multithreaded 
rendering. For example, if you had a dual-processor  hyperthreaded 
computer, choosing 3  would allow you to keep one thread available 
for other tasks while rendering.
