App running slow accessing files across network, process monitor showing lots of entries for app relating to c:\\windows\\csc - why? – superuser

Are you experiencing slow app performance when accessing files across your network? If so, you might notice a lot of entries for your app relating to c:\windows\csc in the process monitor. In this article, we will explain why this is happening and provide some possible solutions to improve your app's speed.

What is c:\windows\csc?

The c:\windows\csc folder is known as the Client Side Cache or Offline Files cache. It is a feature in Windows that allows users to access files stored on a network share even when they are offline. This cache helps improve file access speed and allows you to work with files as if they were stored locally on your computer.

Why is my app accessing c:\windows\csc?

When you access files across a network, Windows automatically checks if those files are available in the Offline Files cache. If the files are cached, Windows will retrieve them from c:\windows\csc instead of downloading them from the network share. This helps reduce network traffic and improves file access speed.

Why is my app running slow?

If your app is running slow when accessing files across the network, it could be due to several reasons:

1. Large cache size: If your Offline Files cache is too large, it can slow down your app's performance. You can check the cache size by following these steps:
   1. Open File Explorer and go to C:\Windows\CSC.
   2. Right-click on the CSC folder and select Properties.
   3. In the General tab, you will see the size of your cache.
   If the cache size is too large, you can reduce it by adjusting the Offline Files settings in the Control Panel.
2. Corrupted cache: If your Offline Files cache becomes corrupted, it can cause slow app performance. You can try clearing the cache by following these steps:
   1. Open Control Panel and go to Sync Center.
   2. Click on "Manage offline files" on the left side of the window.
   3. In the Offline Files tab, click on "Delete temporary files".
   4. Follow the prompts to delete the cache.
   Note that clearing the cache will remove all offline files, so make sure you have a backup if necessary.
3. Network issues: Slow app performance can also be caused by network issues such as a weak Wi-Fi signal or a slow network connection. Make sure your network connection is stable and try accessing the files from a different location or device to see if the issue persists.

By addressing these potential causes, you can significantly improve your app's performance when accessing files across the network. If the issue continues, it may be worth contacting your IT support or the app's developer for further assistance.
