ForceOps 1.3.1

ForceOps

Forcefully perform file operations by terminating processes that are using the file or directory.

Only supports windows, and not planned to support linux.

Uses LockCheck to find processes locking files, and will elevate itself if it the process is owned by another user.

See Benchmarks on github pages.

Refer also to 10.4 Example: file deletion in Windows from "A Philosophy of Software Design", which explains why this is a windows specific problem. Linux does not prevent the user from deleting a file if it is being used, see unlink:

If the name was the last link to a file but any processes still have the file open, the file will remain in existence until the last file descriptor referring to it is closed.

Examples

Deleting when a process owned by the current user is using it

❯ forceops rm .\bin\
[14:55:33 INF] Could not delete file "C:\Users\user\myprogram\bin\Debug\net6\myprogram.dll". Beginning retry 1/5 in 500ms. ForceOps process is not elevated. Found 1 process to try to kill: [100724 - myprogram.exe].
[14:55:34 INF] Could not delete file "C:\Users\user\myprogram\bin\Debug\net6\myprogram.dll". Beginning retry 2/5 in 500ms. ForceOps process is not elevated. Found 0 processes to try to kill: [].

Deleting when a process owned by another user is using it (e.g. a windows service)

Supported operations

Currently, only delete is supported.

Operations like move and copy can have similar issues if they are overriding files or the source file is in use. It would be reasonable to support these operations in a similar way.

For copying, consider using Microsoft.Build.CopyOnWrite.

Usage: As a CLI

To install the CLI, use the latest exe from releases.

Alternatively, it can be installed as a tool, using the .NET 7 SDK.

dotnet tool install -g forceops

To delete a file:

forceops delete file.txt

Usage: As a library

See the ForceOps.Lib package.
