Error uploading large files to Nextcloud Workspace

Valid for Nextcloud Workspace.

If you upload large files to Nextcloud Workspace, problems may occur in exceptional cases, even though there is enough storage space available. This article explains which settings you need to make to the Nextcloud Workspace Windows or Mac client so that the upload works smoothly.

Background for adjusting the upload size

The Nextcloud Workspace client splits large files internally to ensure a smooth transfer. This splitting size is controlled via the maxChunkSize parameter, which is set in the Nextcloud Workspace client on your local computer.

Windows: Set maxChunkSize

Press Windows key + R to open the Run dialogue on your Windows computer.
Enter the following command in the dialog box: %APPDATA%\Nextcloud\nextcloud.cfg
Optional: If .cfg files are not yet linked to a standard application on your computer, select Notepad or another editor.
Add the following line under the [General] section: maxChunkSize=20971520
Save the file and restart your computer.

macOS: Set maxChunkSize

Open a Finder window on your Mac with Command+Shift+G. The Go to Folder dialog box is displayed.
Enter the following command in the dialogue box: $HOME/Library/Preferences/Nextcloud
Activate the display of hidden files with the following key combination: [CMD or Command], [SHIFT], and [.]. All three keys must be pressed simultaneously.
Open the nextcloud.cfg file. If you do not have a standard editor for .cfg files, you can also open the file with TextEdit.
Add the following line under the [General] section: maxChunkSize=20971520
Save the file and restart your computer.

Please Note

Only change the maxChunkSize parameter to the value 20971520. Other values can lead to errors.
