Error
Restore process hang when trying to open a folder that contains a lot of files .
Cause
The issue seemed to be with traversing or browsing the folder before it allows you to select the file to restore .
Fix
We recommend and have tested browsing folders with max. 5,000 files.
In case single files need to be restored in folders with more than 5,000 files, use a complete VM restore and manual file movement as a workaround.
