**nitpick:** Variable shadowing of sFileName may cause confusion.

Consider renaming the inner 'sFileName' variable to avoid shadowing the function parameter and improve code clarity.

**issue (typo):** Typo in return value: 'PFT_Nomral' should be 'PFT_Normal'.

Please update the return value to 'PFT_Normal' to ensure correctness.

```suggestion
+        return PFT_Normal;
```

**issue (complexity):** Consider extracting the file open/seek logic into a helper function to eliminate duplication and clarify intent.

```suggestion
Extract the “open-and-seek” logic into a small helper, then collapse the two branches into a single flow. For example:

```cpp
// Common.h
class Common {
    …
    static bool trySeekFile(const QString& path);
    bool isSupportSeek(const QString& sFileName);
};

// Common.cpp
bool Common::trySeekFile(const QString& path)
{
    QFile file(path);
    if (!file.open(QIODevice::ReadOnly))
        return false;
    bool ok = file.seek(0);
    file.close();
    return ok;
}

bool Common::isSupportSeek(const QString& sFileName)
{
    QFileInfo info(sFileName);
    if (info.exists()) {
        return trySeekFile(sFileName);
    }

    // Create a temp file in the same directory
    QString templatePath = info.absoluteDir().filePath("tempfile_XXXXXX");
    QTemporaryFile tempFile(templatePath);
    tempFile.setAutoRemove(true);
    if (!tempFile.open())
        return false;
    tempFile.write("test\n");
    tempFile.close();

    return trySeekFile(tempFile.fileName());
}
```

Benefits:
- No duplicate open/seek/close
- Single return points for each branch
- Clear intent in `trySeekFile`
```

**issue (complexity):** Consider refactoring the repeated QTimer error-handling code into a helper function and macro to reduce duplication.

Here’s one way to collapse those three identical QTimer blocks into a single helper + guard macro.  This preserves your exact return-values but only writes the “error timer” code once.

```cpp
// In CliInterface.h (or a common private section)
private:
    void emitSeekErrorAndFinish() {
        QTimer::singleShot(1000, this, [this]() {
            m_eErrorType = ET_FileSeekError;
            emit signalprogress(100);
            emit signalFinished(PFT_Error);
        });
    }

#define RETURN_IF_NO_SEEK(retval)           \
    do {                                    \
      if (!m_common->isSupportSeek(m_strArchiveName)) { \
        emitSeekErrorAndFinish();           \
        return retval;                      \
      }                                     \
    } while (0)
```

Then your three methods collapse to:

```cpp
PluginFinishType CliInterface::list() {
    setPassword(QString());
    DataManager::get_instance().resetArchiveData();
    m_setHasRootDirs.clear();
    m_setHasHandlesDirs.clear();
    m_workStatus = WT_List;

    RETURN_IF_NO_SEEK(PFT_Error);

    bool ret = runProcess( /* … */ );
    return ret ? PFT_Nomral : PFT_Error;
}

PluginFinishType CliInterface::extractFiles(...) {
    RETURN_IF_NO_SEEK(PFT_Nomral);

    // … rest of extractFiles …
}

PluginFinishType CliInterface::addFiles(...) {
    // only guard when files not empty
    if (!files.isEmpty()) {
        RETURN_IF_NO_SEEK(PFT_Nomral);
    }

    // … rest of addFiles …
}
```

That removes three copies of the QTimer+lambda while keeping every return‐value exactly as before.

**issue (complexity):** Consider refactoring repeated ET_FileSeekError/EI_FileSeekError handling into helper functions to avoid code duplication.

```markdown
You’re repeating the same ET_FileSeekError/EI_FileSeekError handling in every switch. You can pull that logic out into one helper per subsystem and early‐return, or at least factor the UI messages into a lookup—then each switch only needs:

  1) one `if (eErrorType == ET_FileSeekError) { … }`
  2) a normal switch without the duplicated case

Example for the job‐level error→popup section:

```cpp
// new helper at top of file:
bool handleSeekError(ArchiveJob::JobType jt, ErrorType e, bool needsConfirm)
{
    if (e != ET_FileSeekError)
        return false;

    // map job → FI_*
    FileInterface fi;
    switch (jt) {
    case ArchiveJob::JT_Compress: fi = FI_Compress; break;
    case ArchiveJob::JT_Load:     fi = FI_Load;     break;
    case ArchiveJob::JT_Extract:
    case ArchiveJob::JT_StepExtract: fi = FI_Uncompress; break;
    default:                       fi = FI_Compress; /* fallback */ }

    showErrorMessage(fi, EI_FileSeekError, needsConfirm);
    return true;
}

// in your outer job switch:
case ArchiveJob::JT_Compress: {
    bool needsConfirm = true; // existing logic
    if (handleSeekError(m_eJobType, eErrorType, needsConfirm))
        break;

    switch (eErrorType) {
      // … now no ET_FileSeekError here …
    }
} break;
```

And for the UI‐mapping you can centralize the detail strings:

```cpp
// helper in .cpp
static QString seekDetail(FileInterface fi) {
    switch (fi) {
    case FI_Compress:
      return tr("No compression support in current directory. Download the files to a local device.");
    case FI_Load:
      return tr("Can't open compressed packages in current directory. Download the compressed package to a local device.");
    case FI_Uncompress:
      return tr("No extraction support in current directory. Download the compressed package to a local device.");
    default:
      return tr("Operation not supported in current directory.");
    }
}

// then in your failure‐page switch:
case EI_FileSeekError:
    m_pFailurePage->setFailureDetail(seekDetail(currentFI));
    break;
```

These two small helpers remove all the repetitive `case ET_FileSeekError` and `case EI_FileSeekError` blocks while keeping your behavior identical.
