When transferring a file or folder from a workstation to a CloudConnect Desktop using the Citrix client drive mapping feature, the file transfer becomes unresponsive or fails with a message similar to “Error: Cannot copy (file name):Invalid MS-DOS Function…”
At least one of the files being transferred is larger than 4 GB in size.
Individual files larger than 4 GB may not be transferred using the Citrix Client drive mapping, however a group of files or folders can exceed 4 GB in the aggregate. Large files in user profiles tend to be .pst files, which may be broken up into smaller parts.
Alternatively, use a third party data synchronization software, or request a VPN tunnel from CloudConnect to facilitate the transfer of individual files larger than 4 GB to CloudConnect.
