Details

When using  Horizon Client for Windows to redirect a FAT-32 formatted USB flash drive over a high-latency connection like a VPN or WAN, the process can take several minutes, causing Windows Explorer to appear unresponsive.

Solution

Improve performance over High-Latency connections by switching to FAT or NTFS File Systems

When it comes to redirecting a device over a high-latency connection, FAT and NTFS file systems outperform FAT32. To achieve better performance, it is recommended to back up the existing data on the device, reformat it as FAT or NTFS, and then restore the data on the new file system.

Note: Even with these changes, performance will not match local USB speeds. This is due to the way Windows handles USB data transactions, which are assumed to be over a very short distance. Please see alternate recommendations below:
