Disk Options

Surveyor supports saving and examining very large capture files. Two disk options are available to support large captures, Cache File Location and Disk Capture Location. Choose System Settings… from the Configuration menu and select the Disk Options tab to set either option.

Cache File Location

To support viewing very large captures (greater than 10MB), you can specify the size and location of a disk cache in the Cache File Location area. When decoding large captures, the entire capture typically resides on a remote analyzer device disk, such as in a THGsE. When using Surveyor to view capture contents, the entire capture is not downloaded at once to your local disk; only the parts you access are transferred. However, Surveyor retains the information you have downloaded in a local disk cache, providing faster retrieval of recently downloaded information. You specify the location and size of the cache based on the capacity and configuration of your local system. For example, if your disk drive D: has a capacity of 100GB and your drive C: has a 4GB capacity loaded with operating systems and applications, you could set up a 50GB cache directory on disk drive D:.

Use the Browse button to specify a location for the cache directory and use the slider to specify its maximum size. Surveyor will not allow you to specify a size greater than the available free space on your disk drive. The minimum cache size is 40MB. The cache directory is cleared of files containing information related to a capture when you close the capture or exit the Surveyor application.

Disk Capture Location

To support local disk captures, you can specify the size limit and location in the Disk Capture Location area. Note that this governs the size of large captures created on your local disk but does not affect the size of captures stored on remote analyzer devices. This setting affects only large captures made from THGm cards within your local system. Specify the location of the capture directory based on the capacity and configuration of your local system.

Use the Browse button to specify a location for the capture directory and use the slider to specify its maximum size. Surveyor will not allow you to specify a size greater than the available free space on your disk drive and the minimum size is 40MB. Surveyor uses this directory for all captures made with local cards when using Cap+Disk mode. This is not, however, "permanent" storage of the capture information. Capture information you want to save must be stored in a file using the Save option. The capture directory is cleared of files containing information related to this capture when you close Surveyor.
