In `@app/src/main/assets/wfm/copy-hardening.patch`:
- Around line 361-363: Remove the no-op trailing hunk after
createDesktopShortcuts, including the duplicated unchanged closing brace and its
associated absolute-line dependency; leave the meaningful patch hunks unchanged.
- Around line 342-349: The reparse-point branch in copyPathNative must skip only
the unsupported entry instead of aborting the entire paste. Introduce or reuse a
distinct skipped-result status, propagate it through copyDirectoryNative so
enumeration continues, and ensure fileActionTask continues processing remaining
items while accumulating skipped entries. Report a single summary after the
operation completes, while preserving failure handling for genuine copy errors.
- Around line 68-76: Replace swprintf_s in joinCopyPath with _snwprintf_s using
the _TRUNCATE mode and preserve the existing negative-result failure check.
Apply the same formatting change to the message call at
app/src/main/assets/wfm/copy-hardening.patch lines 47-55; both sites should
treat any negative return as truncation without invoking the invalid parameter
handler.
In `@app/src/main/java/app/gamenative/ui/screen/xserver/XServerScreen.kt`:
- Around line 4014-4017: Ensure WfmInstaller.install(context, container) runs
before every wfm.exe launch path, including Custom Games without a detectable
executable and Steam games with no executablePath, rather than only when
bootToContainer is true. Move the installation call to the shared pre-launch
flow or invoke it unconditionally, while preserving the existing failure
logging.
In `@app/src/main/java/app/gamenative/utils/WfmInstaller.kt`:
- Around line 47-86: Update the existing fast-path condition in installPayload
so it also requires destination.canExecute() to be true, alongside
destination.isFile and the matching SHA-256 hash. This ensures matching files
with missing executable permissions proceed through the reinstall and chmod
path.

Thank you for this one @Nightwalker743 - for wfm, we can add a fork into our GameNative org if needed, would be cleaner than adding patches. On the modern build, these files are downloaded from the server before install, so we'd need to find a way so that it is redownloaded and installed instead of a cached version being used. |

Description
Fix file copy crashes in the Open Container file manager when copying between Wine-mapped drives.
The first file conflict now also offers Replace all, avoiding repeated confirmation prompts when installing mods containing many existing files.
The issue I and another user came across:
Open Container launches Winlator File Manager inside the game's Wine container. WFM delegates copy operations to shell32's
SHFileOperation.On some Wine/Proton configurations, pasting files between mapped drives for example, from D: to A: causes WFM to terminate instead of displaying the expected replacement prompt. This was reproduced with games including Unreal Tournament GOTY and Fields of Mistria.

Checklist
#code-changes, I have discussed this change there and it has been green-lighted. If I do not have access, I have still provided clear context in this PR. If I skip both, I accept that this change may face delays in review, may not be reviewed at all, or may be closed.CONTRIBUTING.md.Summary by cubic
Fixes Open Container copy crashes under Wine by shipping a patched WFM that uses a native Win32 copy instead of
SHFileOperation. Previously, pasting across mapped drives crashed WFM; now copies are stable, resolve drive aliases, block copying a folder into itself, offer “Replace all” on the first conflict, and handle symlinks, long paths, read-only files, and errors.container_pattern_common.tzst;container_files_download.jsonbumped to version 2 with per-component cache markers and SHA-256 verification (reuses only current, verified caches).wfm.exe, verifies the extracted file, and creates missing Wine prefix directories; full extraction remains the fallback.LICENSE.WFM.txtandNOTICE.txt; Open Container launch stays gated and shows a snackbar if installation fails.Written for commit f1a64f7. Summary will update on new commits.
