The SnapKast Folder
SnapKast may no longer start on your computer if you have added or changed any files or directories in the SnapKast folder: My Documents\SnapKast on Windows XP or Documents\SnapKast on Vista and Windows 7.
The SnapKast folder location is for internal use of the SnapKast program. More details are availble below. If you have made changes (e.g. renaming a file), please restore any changes back to their original form. It's best to first ensure that SnapKast is not running (reboot or use the Task Manager), undo any changes you made, then try running SnapKast again.
If you are not sure if you changed anything, then please try the following these steps to see if this is the reason why SnapKast is not starting:
If these steps allow SnapKast to run again, then you need to determine which folder(s) under the SnapKast folder has changed. This can be accomplished by a process of elimination. Let's start with the SnapKast\captured folder as this is the most likely location where the problem lies. Follow the steps below; if you don't find the root cause in the captured folder, then you will need to run through the same steps for all the folders in the SnapKast folder.
The files in the SnapKast folder and sub-folders are for internal use by the SnapKast program. The SnapKast Media Center provides access to any files you may want (e.g. a video MP4 file) and you can drag-and-drop those files from the SnapKast Media Center window to any other folder on your computer as you wish. More information is available on this within the SnapKast User Manual, e.g. in the Playback and Sharing section. Accessing the files in the SnapKast space directly from Windows can cause issues.
