The folder contains only one file, and I am trying Ti.Filesystem.getFile('wrongfile').exists(). It takes 500-600 ms for this call to complete. In comparison Ti.Filesystem.getFile('wrongfile').getSize() returns 0 immediately.\r\n\r\nh4. Workaround\r\nUse Ti.Filesystem.getFile('wrongfile').getSize() instead of exists\r\n\r\n",
