You can edit store files directly from your browser when these are added through Checkout Admin.
In some cases, it is recommended that you select all the content, copy it to an external editor, and then paste the content back onto Admin to complete any updates.
In some situations, Admin file access may be completely compromised.
Try accessing or editing any file through the Admin screen.
To get already uploaded files, you can always access your public route from “/files/file.xyz”.
To update or upload a new file, the user can use the “Available” option in the menu New > File Upload. In this case, simply fill in the destination name and select the file you want to upload.
However, if the file name already exists in the store, the new content will overwrite the previous one and complete the update as such.
