Use a shared folder to store service information (the Use shared settings (multi-user support) box) and path to a shared folder.

Customize the cache memory limits. You may provide for a soft and a hard limit.

In the Soft ﬁeld, specify the maximum volume of cache to be used by the program before it makes an attempt to clear the memory by deleting the data that are not used. The default value is determined automatically on the basis of the amount of RAM on the device with the DICOM Viewer installed.
In the Hard ﬁeld, specify the maximum volume of cache that can be allocated for cached data. The default value is equal to the amount of RAM on the device with the DICOM Viewer installed.

The cache memory limit is speciﬁed in Gibibytes (GiB), accurate to a thousandth, from 0.125 to 999999999999.999. Its value must not exceed the memory size. If you attempt to set a limit exceeding the memory size, a warning message will pop up. The value provided in the Hard ﬁeld must be greater than the value in the Soft ﬁeld. If the limit values fail to meet these requirements, a warning message will pop up.

The ﬁelds for setting cache memory limits are provided with a restore recommended value button . The restore recommended value button is displayed when the limit value provided is diﬀerent from the recommended value. To restore the recommended value of a cache memory limit, click the button in the respective ﬁeld.

After the cache memory limits have been changed, the program must be relaunched. A dialog box will pop up notifying the user of this necessity.
