While uploading large files to Managed Nextcloud, problems may occur in exceptional cases even though there is enough storage space available. This Help Centre article explains to you which settings you need to make in your Managed Nextcloud Windows or Mac client to ensure the upload goes smoothly.

Background for adjusting the upload size

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

Setting maxChunkSize under Windows

Open the Run dialogue on your Windwos computer with Windows key + R.
Enter the following command into the dialogue 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 section [General]: maxChunkSize=20971520
Save the file and restart your computer.

Setting maxChunkSize under MacOS

Open a Finder window on your Mac with Command+Shift+G. The Go to Folder dialogue box is displayed.
Enter the following command into 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 file nextcloud.cfg. 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.

Warning

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