You can take advantage of the large amount of storage in your Office 365 OneDrive account – 1 TB – by uploading the files on your computer to OneDrive. However, you should be aware of the following:
- 20,000 item limit: this includes both folders and files. If you have a folder with 10 items in it, OneDrive sees that as 11 items.
- 2 GB size limit on any file you want to upload.
- Character limit for files and folders: 128 characters for file names and 260 characters for folder names.
- Invalid characters: check to make sure your file or folder names don’t include unsupported characters.
