Method filesystem.delete(+ 1 overload)

Overload

Deletes file or directory if exists.

public static bool? delete(string path, FDFlags flags = 0)
Parameters
path  (string)

Full path.
flags  (FDFlags)
Returns
bool?

true if deleted, false if failed (with flag CanFail), null if did not exist.
Exceptions
ArgumentException

path is not full path (see pathname.isFullPath).
AuException

Failed.

Remarks

Does nothing if it does not exist (no exception). If directory, also deletes all its files and subdirectories. If fails to delete some, tries to delete as many as possible. Deletes read-only files too. Does not show any message boxes etc (confirmation, error, UAC consent, progress).

Some reasons why this function can fail:

  1. The file is open (in any process). Or a file in the directory is open.
  2. This process does not have security permissions to access or delete the file or directory or some of its descendants.
  3. The directory is (or contains) the "current directory" (in any process).

Overload(top)

Deletes multiple files or/and directories.

public static bool? delete(IEnumerable<string> paths, FDFlags flags = 0)
Parameters
paths  (IEnumerable<string>)

string array, List or other collection. Full paths.
flags  (FDFlags)
Returns
bool?

true if deleted all, false if failed to delete all or some (with flag CanFail), null if none existed.
Exceptions
ArgumentException

path is not full path (see pathname.isFullPath).
AggregateException

Failed to delete all or some items. The AggregateException object contains AuException for each failed-to-delete item.

Remarks

This overload is faster when using Recycle Bin. If fails to delete some items specified in the list, deletes as many as possible.
