Files Missing on NetDrive

[pawel]

Hello,

We have noticed that in the last few days, some of our files are missing. My employees have updated the software to the newest version, but that didn’t help. Would you please advise.

Hello Pawel,

Thank you for contacting us.

We are sorry to hear that some files are missing in NetDrive.

First, could you please check whether those files are still visible directly from the original storage service, such as the web interface or native client?
For example, if the files are visible in Google Drive, OneDrive, SharePoint, WebDAV, SFTP, or your NAS, but not visible only in NetDrive, the issue may be related to NetDrive’s file listing cache, permissions, or refresh behavior.

To investigate this further, could you please send us the following information?

1. The storage type you are using
   For example: Google Drive, OneDrive, SharePoint, WebDAV, SFTP, NAS, etc.
2. Your OS version
   For example: Windows 10/11 or macOS version
3. Your NetDrive version
4. The folder path where the files are missing
5. Whether the missing files are visible from the original storage web page or native client
6. NetDrive log files captured right after reproducing the issue, if possible

Please follow these steps:

1. Please set the log level to VERBOSE
2. Reproduce the problem.
3. Afterward, please follow the instructions in the following link to send us the debug log file:

How to attach a log file

1. Change Log Level First, check your settings and change log level to VERBOSE. 1A. If you cannot login At your login screen: [image] Click SETTINGS at the lower right corner. Change Log level to VERBOSE and go back to login screen to apply the change: [image] 1B. If you can login Go to Settings: [image] Change log level to VERBOSE: [22] Set to DEBUG if you use old version because there is no VERBOSE log level. Go back to DRIVES screen. Changed log level takes effect when you leave …

Please be aware that the log file does not contain any login credentials.

In the meantime, please also try the following:

• Disconnect and reconnect the NetDrive drive
• Refresh the affected folder
• Completely exit NetDrive and start it again
• Check the original storage directly with the same account to confirm whether the files still exist

Once we receive the details and logs, we will check whether there is any error while NetDrive is listing the files.

Thank you.

Hi there!

Thank you for getting back to me. Here are answers to your questions:

1. NAS
2. macOS Tahoe 26.4.1
3. Netdrive3 version 3.19.28
4. Under 2DesignGroup. Inside, there were more folders showing which now are not.
5. I’ve only accessed files through Netdrive3 so not sure how to check this through NAS
6. Not sure

Please see the attached log files. If you need more information, please let me know.

Hello Pawel,

Thank you for sending the log files.

After reviewing the logs, this does not look like a simple file listing issue caused by the latest NetDrive version. The logs show that delete requests were made against the NetDrive-mounted volume around April 28, 2026.

For example, we found entries similar to the following:

Unlink: [/Volumes/TEAM_WebDAV_pawel:rm] => ... : /2DesignGroup/...

Unlink means a file delete request, and rm indicates that the request appears to have come from a macOS rm process, or from an application/script using rm.

We also see many FUSE_unlink: 0 entries in the log, which usually indicates successful unlink/delete operations at the filesystem level. This suggests that multiple delete operations may have been successfully executed through the mounted NetDrive volume.

On the other hand, in the May 5 log, NetDrive successfully retrieved the /2DesignGroup folder listing from the NAS/WebDAV server using PROPFIND with HTTP 207 responses. So at that time, NetDrive was able to connect to the NAS and read the folder listing successfully.

Based on the current logs, it looks more likely that files or folders may have been deleted through the NetDrive-mounted path, rather than NetDrive simply hiding them.

Could you please check the following?

1. Log in directly to your Synology NAS / DSM / File Station and check whether the missing folders still exist under /2DesignGroup.
2. Check the NAS Recycle Bin, Snapshot Replication, or Hyper Backup for recovery options around April 28, 2026.
3. Check the NAS File Station/WebDAV logs for DELETE requests around April 28, 2026, especially between approximately 20:25 and 21:22 according to the NetDrive log timestamps.
4. Check whether any Terminal command, cleanup script, backup/sync tool, or automation ran on the Mac or employee computers around that time.

At this point, the logs do not indicate that NetDrive itself randomly hid or removed the folders after the update. Rather, they show delete requests coming through the mounted drive, which NetDrive would then pass to the NAS/WebDAV server.

If the files are also missing directly from the NAS, the fastest recovery path would likely be the Synology Recycle Bin, Snapshot, or backup restore.

For further investigation, please send us:

• A few examples of the missing folder/file names
• Whether those files are visible directly in Synology DSM/File Station
• NAS WebDAV/File Station logs if available
• Whether any backup, sync, cleanup, or automation tool was running around April 28

Thank you.
