SecureErase (delete file)

function SecureErase(what: string, passes: number): boolean;

This function tries to delete the what file from the local file-system using a secure erasure algorithm. This means that the file will be overwritten with crypto-secure pseudo-random data before it’s actually deleted from the storage medium, in order to make it unrecoverable. For this reason, depending on the size of the file, this function may take a while to complete.

The second parameter passes is optional, and specifies how many times the file needs to be overwritten with crypto-secure pseudo-random data before the actual deletion occurs. If left unspecified, the file will be overwritten only once and then deleted.

This function accepts the following parameters:

Possible return values:

Example (Windows file system, no optional parameter)

{
  if (SecureErase('C:\\Data\\SomeFile.docx')) {
    // ...
  }
}

Example (Linux file system, with optional parameter)

{
  if (SecureErase('/home/someuser/data/SomeFile.pdf')) {
    // ...
  }
}
