It is critical that Cassini Disk capacity remain under 80% utilization for nominal performance. Use the steps below to check Disk Use % and individual sizes of Folders. The C-Drive contains the OS and the D-Drive contains RI Application in D:\RiApps\ and local Guru Repository in D:\RiGuru.

To Check Disk Use%:

1. Open a command window and type:
   df -h
2. Results are presented similar to below.
   Filesystem      Size  Used Avail Use% Mounted on
   OS              4.0G  1.1G  3.0G  26% C:/
   Application     4.0G  708M  3.3G  18% D:/

To Check Folder Size:

1. Open a command window and type:
   d:
   du -sh *
2. Results are presented similar to below. First column is disk size of the folder name in the 2nd column.
   100K    lost+found
   104K    GuruKeys
   187M    RiApps
   212M    RiGuru
   32K     Testdata
   4.0K    ACSdata
   4.0K    pdfs
   4.0K    ScreenShots

To Recover Disk Space on Cassini System Controller (EPC or VM):

1. Any files deleted with the Workspace Drives and Folders are added to the Trash Can. Empty the Trash can by choosing Desktop > Trash can then, Folder > Empty trash can... menu or at Shutdown (See Figure 2).
2. Identify a folder in the table below and open a command window and type:
   rf -rf <<Folder>>
3. Follow the steps To Check Disk Size again.
4. If D:\ is still above 80% Use%, then use the command to Check Folder Size and remove any additional folders from the list below. Remove D:\Testdata as a last resort.

Cassini System Controller (EPC) Temporary Folders
It is safe to remove the contents of the following folders while not running a production Test Exec (Pause OK). Cassini and other applications can be left running.
IMPORTANT: NEVER remove D:\RiGuru (local repository) or D:\RiApps (local applications).

Folder	Contents
D:\RiGuruArchive	Copy of everything in D:\RiGuru\repository\, rebuilt on startup and created as new guru objects are created, used to access file if corruption after write detected
D:\ACSdata	AutoCorr System (ASC) Datalogs and Correlation data. Do not remove while AutoCorr is active with Cassini running a Test Exec with Bias Control enabled.
D:\ScreenShots	Output of PMCam (Print Screen key)
D:\Shared	Recommended folder for .GZP files from Guru Browser
D:\pdfs	PDF Writer Output (System Settings > PMPDF Control Panel) used for Lot Summary Report Note: failes may also appear .pdf files in D:\)
D:\Testdata	Output of local RITdb file used to display Cassini Worksheet. Output of Lot Summary report any recommended folder for Exported STDF from Guru Browser or STDF Copy Agent
