It supports paths as long as 32767 characters. 5 | It works by using extended-length paths and the Unicode versions of the WinApi functions for enumerating and deleting files. 6 | In addition, it supports bypassing ACL checks for deleting folders if the user has administrative rights on the drive. 7 | 8 | More info about the mechanism can be found in MSDN article [Naming Files, Paths, and Namespaces](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx), in section "Maximum Path Length Limitation". 9 | 10 | It's written in C#/NET and provides VS projects for building for .NET 3.5, 4.0, 4.5, 4.6 11 | 12 | ### Usage 13 | 14 | It's fairly simple. Just open a command-line window and run the tool. It takes only one parameter, which can be a full file or folder path. 15 | 16 | #### With confirmation 17 | ``` 18 | SuperDelete.exe fullPathToFileOrFolder 19 | ``` 20 | 21 | #### Silent mode 22 | The tool supports an additional command line argument which suppresses the confirmation message. Could be used in automating some tasks. The argument is --silent or -s. 23 | 24 | ``` 25 | SuperDelete.exe --silent fullPathToFileOrFolder 26 | ``` 27 | 28 | #### Bypass ACLs 29 | In the case where the user has administrative rights on the drive, the tool can bypass ACL checks and remove the file even if the user doesn't have rights in the ACL. 30 | This is useful in cases where a drive is moved from another machine or Windows installation. 31 | 32 | ``` 33 | SuperDelete.exe --bypassAcl fullPathToFileOrFolder 34 | ``` 35 | 36 | #### Printing stack trace 37 | If there is an exception, this will print the callstack where the exception occurred. This is mostly useful for debugging. 38 | 39 | ``` 40 | SuperDelete.exe --printStackTrace fullPathToFileOrFolder 41 | ``` 42 | 43 | ### Downloads 44 | 45 | The latest release is SuperDelete 1.2.0 and you can get it from the [Releases](https://github.com/marceln/SuperDelete/releases) page. 46 | -------------------------------------------------------------------------------- /SuperDelete.sln: -------------------------------------------------------------------------------- 1 | 2 | Microsoft Visual Studio Solution File, Format Version 12.00 3 | # Visual Studio 14 4 | VisualStudioVersion = 14.0.24720.0 5 | MinimumVisualStudioVersion = 10.0.40219.1 6 | Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "SuperDelete_45", "SuperDelete\SuperDelete_45.csproj", "{73C128EB-25B5-4C97-A363-F1CCFA2B5DDC}" 7 | EndProject 8 | Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "SuperDelete_35", "SuperDelete\SuperDelete_35.csproj", "{062F49F7-1288-4756-BBC8-DEDBFE2C837E}" 9 | EndProject 10 | Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "SuperDelete_40", "SuperDelete\SuperDelete_40.csproj", "{86D05A38-2BAB-4053-84D7-D23601923381}" 11 | EndProject 12 | Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "SuperDelete_46", "SuperDelete\SuperDelete_46.csproj", "{1D3684A6-9F4C-4786-A357-45A8BF5438B7}" 13 | EndProject 14 | Global 15 | GlobalSection(SolutionConfigurationPlatforms) = preSolution 16 | Debug|Any CPU = Debug|Any CPU 17 | Release|Any CPU = Release|Any CPU 18 | EndGlobalSection 19 | GlobalSection(ProjectConfigurationPlatforms) = postSolution 20 | {73C128EB-25B5-4C97-A363-F1CCFA2B5DDC}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 21 | {73C128EB-25B5-4C97-A363-F1CCFA2B5DDC}.Debug|Any CPU.Build.0 = Debug|Any CPU 22 | {73C128EB-25B5-4C97-A363-F1CCFA2B5DDC}.Release|Any CPU.ActiveCfg = Release|Any CPU 23 | {73C128EB-25B5-4C97-A363-F1CCFA2B5DDC}.Release|Any CPU.Build.0 = Release|Any CPU 24 | {062F49F7-1288-4756-BBC8-DEDBFE2C837E}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 25 | {062F49F7-1288-4756-BBC8-DEDBFE2C837E}.Debug|Any CPU.Build.0 = Debug|Any CPU 26 | {062F49F7-1288-4756-BBC8-DEDBFE2C837E}.Release|Any CPU.ActiveCfg = Release|Any CPU 27 | {062F49F7-1288-4756-BBC8-DEDBFE2C837E}.Release|Any CPU.Build.0 = Release|Any CPU 28 | {86D05A38-2BAB-4053-84D7-D23601923381}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 29 | {86D05A38-2BAB-4053-84D7-D23601923381}.Debug|Any CPU.Build.0 = Debug|Any CPU 30 | {86D05A38-2BAB-4053-84D7-D23601923381}.Release|Any CPU.ActiveCfg = Release|Any CPU 31 | {86D05A38-2BAB-4053-84D7-D23601923381}.Release|Any CPU.Build.0 = Release|Any CPU 32 | {1D3684A6-9F4C-4786-A357-45A8BF5438B7}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 33 | {1D3684A6-9F4C-4786-A357-45A8BF5438B7}.Debug|Any CPU.Build.0 = Debug|Any CPU 34 | {1D3684A6-9F4C-4786-A357-45A8BF5438B7}.Release|Any CPU.ActiveCfg = Release|Any CPU 35 | {1D3684A6-9F4C-4786-A357-45A8BF5438B7}.Release|Any CPU.Build.0 = Release|Any CPU 36 | EndGlobalSection 37 | GlobalSection(SolutionProperties) = preSolution 38 | HideSolutionNode = FALSE 39 | EndGlobalSection 40 | EndGlobal 41 | -------------------------------------------------------------------------------- /SuperDelete/Internal/ProgressTracker.cs: -------------------------------------------------------------------------------- 1 | //Copyright 2015 Marcel Nita (marcel.nita@gmail.com) 2 | // 3 | //Licensed under the Apache License, Version 2.0 (the "License");
