Windows 7 Can't share ONE folder.

It seems like you've set up sharing for multiple folders on Windows 7, specifically for your PS3 to access media content. However, you are facing an issue where one specific video folder is not appearing on your PS3, despite trying various troubleshooting steps. Here are a few potential reasons why this particular folder might not be appearing on your PS3: 1. File Permissions: Even though you mentioned that you checked the sharing and security permissions on all folders, it's worth verifying the permissions on the folder that's not showing up on the PS3. Ensure that the PS3 has the necessary permissions to access that folder. 2. File Format Compatibility: The PS3 has specific media format compatibility requirements. If the videos in the folder that's not showing up are in a format not supported by the PS3, they may not be visible. Make sure the videos are in a format that the PS3 can play. 3. Network Issues: There could be network issues preventing the PS3 from accessing that specific folder. Check the network connection between your Windows 7 PC and the PS3 to ensure they are properly connected. 4. Media Library Update: Sometimes, media devices like the PS3 need time to update their libraries. Try resetting the PS3 or refreshing the media library on the PS3 to see if the folder appears after the update. 5. DLNA Server Configuration: If you are using Windows Media Player 12 as a DLNA server to stream media to the PS3, ensure that the settings in WMP12 are correctly configured for sharing media. You may need to check the sharing settings within WMP12. 6. Folder Content Issues: Check the folder that's not appearing for any issues such as corrupted files, special characters in file names, or hidden files that might be causing the problem. 7. Reboot Devices: Sometimes, a simple reboot of both the Windows 7 PC and the PS3 can resolve network and sharing issues. Try restarting both devices and see if the folder appears on the PS3. By investigating these possibilities and taking appropriate actions, you should be able to troubleshoot why that particular video folder is not appearing on your PS3. Let me know if you need further assistance or if you have tried any of these steps already.
