Compress files (Also applies to the SourceDataDir)

If possible, put the CalcCache to a folder on a disk with an NTFS partition. The NTFS disk management system allows you to keep files in a compressed format on disk. The following steps are needed to store files compressed:

  1. Browse in the Windows Explorer to your LocalDataDir, or to the overruled location of the CalcCacheDir in the config.ini.
  2. View the properties (right mouse click), a following dialog appears (Windows 7 layout):
    CalcCacheProperties
  3. Click the Advanced button, a following dialog appears (Windows 7 layout):

    CalcCacheAdvanced

  4. Activate Compress contents to save disk space (third checkbox) and deactivate Indexing Service (second checkbox). Indexing on CalcCache folders is not useful and makes you system slow. In case the selected folder already contains files and subfolders, a following dialog appears (Windows 7 layout):

    CalcCacheConfirm

  5. Choose the option as indicated, so including subfolders and files

Dependent on the amount of data in the folder and subfolders, the process to compress files can take some time.

The advantage of storing files compressed is that the amount of disk space is saved substantially. Furthermore the GeoDMS can read the compressed files faster, as less disk access is needed. A small disadvantage is that writing files take some more time, as the data need to be compressed first. But still it is advisable to keep the files compressed on disk.
