long delay while opening folder files in ubuntu14.04 [closed]

Folder file appears empty for few minutes even though it contains file in it. any solutions to get rid of this. os is ubuntu 14.04

May be lack of memory, or a failing disk, since your problem is not the "I have 40,000 pictures in a directory and it's slow to open" sort of thing. Open a terminal with Ctrl-Alt-t and

1. Check the free memory

   free --human
   

   Post the results in your question.

2. From the install media, run the memory check to confirm it's OK.

3. From the install media, maybe run the file system check, but if this is a new install, that's probably not the problem. Command in a terminal will look like (assuming sda and partition one, change to meet your setup)

   sudo fsck /dev/sda1
   

4. Install the smartmontools and check your disk

   sudo apt-get install smartmontools
   sudo smartctl -a /dev/sda  
   

   (Assuming your disk is sda)
