You may run BCWipe commands to wipe free space on the disk and delete files or folders with wiping from the command line prompt.


This allows you to insert wiping commands to your batch (*.bat) files and then run the batch file when you wish to run a number of wiping procedures with custom parameters.


BCWipe Setup program installs the program BCWipe.exe to the directory you have chosen during installation.


All the commands of the BCWipe.exe program include the Mode parameter, which describes wiping scheme and can be one of the following:


  • DoD - Seven passes predefined pattern scheme according to the US DoD 5220.22-M* standard, (default scheme);
  • PG - Peter Gutmann 35-passes predefined pattern scheme;
  • PF[file path name] - Previously created file with custom wiping scheme;
  • PS[scheme name] - User defined wiping scheme, created with Wiping Scheme Editor
  • UD[1..100] - User Defined Number of wiping passes (first passes use complement patterns, the last pass uses random buffer);

Delete with wiping


To delete files or folders run BCWipe.exe this way:

BCWipe Delete [-Mode] [-Options] [file or folder name or @listFile] [file or folder name]...

[Options]

  • NoSwapFile - Disable swap file wiping;
  • NoDirEntries - Disable everything: MFT records and Directory Nodes/Entries;
  • NoDirectoryNodeSlack - Disable Directory Entries wiping on FAT and Directory Nodes wiping on NTFS ;
  • NoMFTRecords - Disable MFT records wiping;
  • NoNTFSLogFile - Disable NTFS Log File ($Logfile) wiping;
  • NoVerification - Disable disk-level verification;
  • disableSR - Delete Restore Points;
  • View - Start BCView after wiping file contents and before final deleting the file.
  • @listFile - Text file where every file name starts from a new line.



EXAMPLES:
> BCWipe Delete -PG -NoSwapFile -NoDirEntries -View C:\SecureData.doc
> BCWipe Delete C:\Test
will delete ALL FILES IN THE FOLDER , and REMOVE THE FOLDER ITSELF! Compare the command with the following one:

> BCWipe Delete C:\Test\*.*
In the last example BCWipe deletes files inside the Test folder, but does not delete the folder.



Swap file wiping


To wipe the swap file, run BCWipe.exe with the following parameters:

BCWipe WipeSwapFile [-Mode]

EXAMPLE:
> BCWipe WipeSwapFile -UD1



File slacks wiping


To run BCWipe for wiping file slacks, run BCWipe.exe with the following parameters:

BCWipe.exe FileSlack [-Mode] [-Options] [file or folder name or @listFile] [file or folder name]...

[Options]

  • View - Start BCView twice before and after file slack wiping.
  • @listFile - Text file where every file name starts from a new line.

EXAMPLE:
> BCWipe FileSlack -UD3 -View C:\Test.txt

Note that when you run BCWipe.exe with the FileSlack parameter, the program does not shred the file itself, it only wipes slack of the file. Neither contents of the file, nor its attributes become changed.


ATTENTION: the BCWipe.exe utility works without asking any additional confirmation for deleting files and for wiping free space on the disk. The program is designed so to provide a silent functionality when you run it from batch files.



Common options:


  • -Hidden - run the wiping process in background, not reports to the screen, no interaction with the user;
  • -SuperHidden - same as previous, but it also hides the wiping progress bar;
  • -ExtendedErrorCodes - activates extended error code mapping;
  • -LF [log file name] - assigns log file for wiping process, use quote for names containing spaces.
  • -LS[size in KBytes] - allows size limitation for the log file.
  • -ErrorLoggingOnly - only log strings containing ‘Error’;
  • -ForceAPI - if all options are disabled, BCWipe won't load DefragAPI module. This flag forces BCWipe to load it anyway. It may be required to properly wipe encrypted/compressed files;


EXAMPLE:
> BCWipe Delete -Hidden -LF "C:\BCWipe.log" –LS200 C:\Test\*.*
