User Case: iCloud Drive Size Incorrect


I just installed macOS Sierra and synched my Documents and Desktop to iCloud. That is a cool feature but I have one problem. In the iCloud settings, the green 'Documents' bar shows that I have 3.22 GB of documents. When I open the iCloud Drive, I see there two folders: Desktop and Documents. And these two are the only folders there. In my hard drive, the size of Desktop is 1.9 MB and the Size of Documents is 1.65 GB. I even chose not to 'Optimize Mac storage' and hence I assume that the size of the folders should be identical on my local hard drive and in iCloud Drive. Any ideas why the iCloud thinks there is almost two times more data than what I have uploaded to iCloud? This is frustrating since I seem to have no means to free that storage space and now my iCloud is constantly giving a warning that it is nearly full.

Why iCloud Drive Shows Wrong Size?

One of the common scenarios faced by iCloud users is the incorrect display of storage size in their iCloud Drive. This issue can arise due to various factors, including temporary file storage, sync problems, and hidden files and folders. Let's examine each of these potential causes in detail:

  • Temporary File Storage: iCloud Drive may accumulate temporary files that occupy space but are not accounted for accurately in the size calculation. These files can result from activities such as app downloads, file edits, or system backups. While these temporary files serve a purpose, they can occasionally contribute to the discrepancy in iCloud Drive size.
  • Sync Issues: Syncing your iCloud Drive across multiple devices is a convenient feature, but it can also lead to size inconsistencies. If the sync process encounters errors or interruptions, it may fail to update the storage size correctly across all your devices, leading to inaccurate information being displayed.
  • Hidden Files and Folders: Hidden files and folders on your iCloud Drive can also contribute to the incorrect size representation. These hidden items, such as system files or application data, are typically excluded from regular view but can still occupy storage space. Failing to account for these hidden components can result in a mismatch between the reported and actual storage usage.
