The following file systems are supported by myCloud Desktop:
Case sensitive file systems are not suported.
ARM processors are not supported.
External and Network drives are only supported for myCloud Computer Backup (available in the myCloud Pro Edition), not for the myCloud synchronization folder.
Due to technical reasons, our system is subject to some limitations. Here is a list of the most relevant of them:
< (less than)
> (greater than)
“ (quotation mark)
| (vertical bar)
? (question mark)
. (period) as the first character in the file name
Spaces at the beginning or end of the folder/file name are not supported.
Since macOS allows to insert spaces at the beginning/end of names and other operating systems do not allow this, this may cause that the synchronization cannot be completed if you work e.g. with a Windows PC and Macbook simultaneously.
Maximum/minimum file size:
Files from 0 byte up to a maximum file size of 3 GB (myCloud Light/Standard Edition) resp. 20 GB (myCloud Pro Edition) are supported.
Unsupported file types:
Maximum length of file names
The maximum file name length is 255 characters.
Maximum number of files
The maximum number of files that can be synchronised without inhibiting performance is 100,000.
Maximum number of subfolders
The maximum number of subfolders per folder is 10,000.
Maximum number of folders
The maximum number of folders is 10,000.
Maximum path length
The maximum number of characters allowed in a file path (path and file name) is 260.
Symbolic links (also called symlinks or soft links) in your myCloud directory are ignored and therefore not synchronised with myCloud.
Minimum internet speed
The minimum speed required for myCloud Desktop to work properly is: 5 MB Download / 1 MB Upload
Direct synchronization of programs in the myCloud folder
We do not recommend setting the default storage path of programs to the myCloud folder, as programs create temporary files when editing and opening files that cause synchronization problems.
