Informatec Digital » The Cloud » Google Drive won't sync files: Causes, solutions, and tricks for Windows, Mac, and Android

When Google Drive does not sync files When a problem occurs between your device and the cloud, the problem can range from something as simple as an unstable connection to corrupted system permissions. This article compiles everything you need to diagnose and fix sync issues on Windows, macOS, and Android, including special cases like corrupted Google files or disappearing folders.

The idea is that you can start with Basic checks and move on to deeper solutions if it still doesn't work. You'll also find specific settings for permissions, paths, size and bandwidth limits, as well as what to do with the Lost & Found folder, advanced steps for macOS, and practical recommendations for mobile use.

Common causes and symptoms

First of all, it is important to identify the situation: error messages, warnings that "there is little space left", files that do not upload or changes that are not reflected between your computer and "My Drive." Sometimes Drive for computers freezes, crashes, or doesn't start at all.

The most common causes include Internet problems, insufficient system permissions, antivirus or proxy conflicts, file size limits, moved/renamed paths, full local or cloud storage, and on mobile devices, data restrictions or corrupted cache.

Essential basic steps

Start with the basics: many incidents are resolved with quick actions that reactivate synchronization without touching anything complex.

• Check the connection: make sure your computer has stable internet. Reboot your router if necessary.
• Restart Drive for PC: On Windows (system tray) or macOS (menu bar), go to Settings → Logout and reopen the app.
• Restart your computer: A clean reboot can release blocks Temporary
• Disconnect and reconnect your account: In Preferences → Advanced Settings, tap Disconnect account and log in again.
• Reinstall Drive for computers: download the latest version from the official website and install it from scratch.

Important when disconnecting: Unsynced files may be moved to "Lost and Found" and They are deleted if you unlink the account; copy them to a safe place first.

Storage and space problems

Drive requires local disk space to operate, even in streaming mode. If you see the warning little disk space, free up space on the specified drive (e.g., C:) and restart the application.

If the blockage comes from the cloud side, your google storage is full, or the file owner (if not yours) doesn't have enough space. Ask them to free up space or transfer ownership to you if you need to continue editing.

Permissions and access in Windows and macOS

Without proper permissions, Drive cannot read/write or sync. In Windows, open the Properties → Security tab of the file or folder and verify that your user has Allow in all permissions (and nothing marked as “Deny”).

On macOS, right-click → Get Info → Sharing & Permissions and confirm that your user has the privilege to Read and write. If applicable, grant additional access in System Preferences → Privacy & Security (for example, Photos or specific folders).

File size and type limits

For Google Photos in Drive, there are restrictions: photos larger than 200 MB or 150 MP, videos larger than 10 GB or images smaller than 256×256 aren't backed up. If something isn't uploading, reduce the size, delete the file, or move it to a folder that doesn't sync.

Be careful with thumbnails or other files that some apps automatically create below the threshold; they can generate silent errors synchronization.

Google Drive folder moved, renamed, or deleted

If you changed the location or name of your Drive folder, the app may display a prompt to "Locate" and reconnect. Select the folder with the current name and accept. The process will take a while to complete.

Did you delete the folder you were replicating "My Drive" to? In the notification, choose Stop syncing this directory or adjust in Preferences which folders you want to sync or exclude.

Missing files in the cloud or on your computer

If a file has been deleted in Drive or is no longer shared with you, local changes won't be able to upload. Ask the owner to share again the item or remove it from the synced folder and upload it again.

If the file disappeared from your computer (or is in the local trash), restore it so you can synchronize changes. Otherwise, delete the local file if you prefer to clear the error.

Bandwidth, upload and download limits

Drive for computers automatically retries when the time limit is exceeded. temporary quotasIf it doesn't resume, wait 24 hours and restart the app to force a new attempt.

Corrupted Google files (.gdocs, etc.)

Google Docs are not saved as "full" files on your computer: if a third-party editor modifies those shortcuts, they can corrupt. Create a copy of the original on Drive web and delete the invalid file on your computer. You may need to re- share the new link.

Startup and account load errors

If the account does not load, check: Internet connection, that there is free drive letter (Windows), that proxy settings don't block the app, and that your organization allows Drive on that device.

There may also be issues with the chosen "streaming location": if it is a busy drive letter, the app will choose the one next available. Disconnect the device that uses that letter if you want to keep it.

To have Drive boot with the system, in Preferences activate the option "Open Google Drive on startup"; you'll avoid forgetting things that end up in outdated folders.

Lost and Found: What It Is and How to Act

In rare cases (permissions, network, or other), Drive can't upload a file and copies it to "Lost & Found" on your hard drive. You'll see a notification with a shortcut. Default locations: macOS: /Users/ /Library/Application Support/Google/DriveFS/lost_and_found/; Windows: C:\Users\ \AppData\Local\Google\DriveFS\lost_and_found\.

Note that the "Library" folder on macOS is hidden and on Windows you can write % AppData% in the address bar to access AppData. Review those files, move them to "My Drive" to retry the upload, or place them in another local folder of your choice.

Warning: yes you disconnect your account, items saved in "Lost and Found" may be lost. Copy them first.

Advanced macOS Fix: Repair Extension Permissions

In macOS High Sierra or Mojave, the permissions required for syncing may become corrupted. You must have the administrator and your password to execute the steps.

1. Open Finder → Applications → Utilities → Bus Terminal.
2. Run: sudo kextcache -clear and press Enter.
3. Run: sudo mv /private/var/db/KernelExtensionManagement /private/var/db/KernelExtensionManagementBackup and press Enter.

5. Start over Drive for computers.

These commands force the reconstruction of key components and usually resolve issues with kernel extensions related to DriveFS.

Permissions on the configuration folder and local cache

The settings folder stores critical data; if you don't have full ownership and permissions, Google Drive can not to start or fail.

• macOS: Grant permissions to /Users/ /Library/Application Support/Google and verify that it exists DriveFS after starting the app.
• Windows: Check C:\Users\ \AppData\Local\Google\ y C:\Users\ \AppData\Local\Google\DriveFS.

For the "locally cached files" directory, enter the path provided by the app and make sure that each account folder (long numeric names, e.g., 1245555729303) and its subfolder content_cache have read and write permissions.

PDF-oriented alternative: management and synchronization with UPDF Cloud

If you are most interested in working with PDF documents and need reliable synchronization, you may want to consider UPDF Cloud (integrated into UPDF) as an alternative to centralize and edit PDF with military-grade encryption and real-time synchronization between devices.

• Edit PDF: Tools for text, fonts, colors, images, hyperlinks, watermarks, and backgrounds.
• Annotate PDF: comments, highlighting, shapes, lines, stickers, stamps and signatures.
• Organize PDF: reorder, rotate, extract, add pages, merge, and split; bookmarks, TOC, headers, and footers.
• OCR: Convert scans into editable, searchable PDFs, streamlining work with physical documents.

If you have gone through all the sections, you now have a complete plan: from the most basic (connection, restarts, closing and new session) to the advanced (permissions, routes, limits, "Lost and found", repair in macOS, proxy, antivirus and mobile settings), with which you resolve Google Drive sync and prevent future blockages in your workflow.
