From 296d8f87b645c09bd2fe6f7866992ec2288bcd32 Mon Sep 17 00:00:00 2001 From: Copilot <198982749+Copilot@users.noreply.github.com> Date: Mon, 29 Sep 2025 09:11:28 +0800 Subject: [PATCH] Fix: Prevent backup directory creation during dry runs (#41460) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary This PR fixes an issue where the backup folder was being created unnecessarily when users navigated to the General tab in PowerToys Settings, even when no actual backup had been triggered. ## Problem When opening PowerToys Settings and navigating to the General tab, the backup directory (default: `~/Documents/PowerToys/Backup`) was automatically created, even though no backup operation had been performed. This caused confusion for users setting up PowerToys on new devices, as they would always need to manually clean up the unwanted default folder when configuring a custom backup path. ## Root Cause The issue occurred because: 1. Loading the General tab triggers `RefreshBackupRestoreStatus()` 2. This calls `DryRunBackup()` to check backup status 3. `DryRunBackup()` executes `BackupSettingsInternal()` with `dryRun=true` 4. However, the directory creation logic (`TryCreateDirectory`) was running regardless of the dry run flag ## Solution The fix ensures that directory creation only happens during actual backup operations: **Primary Change**: Wrapped backup directory creation in a dry run check: ```csharp // Only create the backup directory if this is not a dry run if (!dryRun) { var dirExists = TryCreateDirectory(settingsBackupAndRestoreDir); if (!dirExists) { Logger.LogError($"Failed to create dir {settingsBackupAndRestoreDir}"); return (false, $"General_SettingsBackupAndRestore_BackupError", "Error", lastBackupExists, "\n" + settingsBackupAndRestoreDir); } } ``` **Consistency Change**: Also moved temporary directory creation inside dry run checks to maintain consistent behavior throughout the backup process. ## Impact - ✅ **General tab loading**: No longer creates unwanted backup directories - ✅ **Actual backup functionality**: Remains completely unchanged - ✅ **User experience**: Clean setup without unwanted default folders - ✅ **No breaking changes**: All existing backup/restore features work as before ## Testing Created comprehensive tests to validate: - Dry runs (General tab loading) don't create directories - Actual backup operations create directories as expected - No regression in existing backup/restore functionality Fixes #38620. > [!WARNING] > >
