Summary: The user reports that draw.io repeatedly shows a 'file has been modified' warning when working with a local .drawio file that has 60+ tabs/pages, despite not being connected to any cloud service. This may be related to file size triggering external modification detection or a cloud sync folder inadvertently modifying the file.

📝 Additional Information Needed

To help us investigate this more effectively, could you please provide:

• Environment: Please specify: draw.io version, platform (desktop app or web), operating system, and browser (if web).
• Steps to reproduce: Can you describe the exact steps to reproduce this? For example: 1) Open a local .drawio file with 60+ tabs, 2) Edit a diagram, 3) Save — does the 'file has been modified' warning appear immediately, after a delay, or repeatedly?
• Expected behavior: Please confirm: you expect no 'file has been modified' warning when you are the only one editing a local file, correct?
• File size and format: How large is the file (in MB)? Is it saved as .drawio (XML) or .drawio.png / .drawio.svg? Is it stored on a local disk or a synced folder (e.g., OneDrive, Google Drive, Dropbox)?
• Sync folder check: Even though you mention 'local mode', is the file located in a folder that is synced by any cloud service (OneDrive, Dropbox, iCloud, Google Drive, etc.)? These services can modify file metadata and trigger the 'file has been modified' warning.

We also have some questions:

• Is the file stored in a folder managed by a cloud sync service (OneDrive, Dropbox, iCloud, Google Drive)? Even without explicitly connecting draw.io to a cloud, if the file resides in a synced folder, the sync client can trigger external modification detection.
• Does this issue occur with smaller files (e.g., fewer than 10 tabs), or only once you have 60+ tabs?
• Are you using the desktop (Electron) app or the web version of draw.io?
• Does the warning appear during editing, or only when you try to save?
• If you are on the desktop app, does the issue persist after restarting the application?
