I often need to upload files to Microsoft OneDrive, whose max size per file with my account is 15 GiB.

How can I add an entry in the context menu in Windows Explorer to split files by 15 GB chunks?

Ideally I'd prefer if one could select several files and split each of them by 15 GB chunks at once. But even just splitting 1 file would be convenient.


7-zip doesn't have this function by default:

I don't want to have to manually define the split for each file:

This possible solution involves editing the registry.

  1. Press Win+R, type regedit.
  2. Open HKEY_CLASSES_ROOT\*\. Select shell.
  3. Right-click shell, select New then Key. Name it Split.
  4. Double-click Default and enter Split to 15GB.
  5. Right-click the key Split, select New then Key. Name it command.
  6. Double-click Default and enter C:\Program Files\7-Zip\7zG.exe a -v15g "%2%1.zip" "%1"
  7. Right-click the file you want to split. Select Split into 15GB.

The following simply automates Reddy Lutonadio's answer:

Save as a .reg the following code, execute it, and restart explorer.exe:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\*\shell\Split]
@="Split to 15GB"

[HKEY_CLASSES_ROOT\*\shell\Split\command]
@="C:\\Program Files\\7-Zip\\7zG.exe a -v15g \"%2%1.zip\" \"%1\""

You'll see the new Split to 15GB entry in the contextual menu:

To confirm, this is what you should see in registry:
