Files not updating in folder
I have a HTML application that interfaces to my Hauppage WinTv card. This HTML app takes a snapshot of 3 different channels at approximately 30 second intervals and saves the snapshot to a jpeg file in a selected folder. The jpeg files will be replaced by more current files for the first 10 minutes the app is running. But eventually, the snapshots in the folder will NOT be replaced by more current snapshots. But if I open a command prompt to the folder storing the jpeg files and do a DIR command several times, the current files start to be replaced by the latest snapshot.
Thus, I have to execute DIR commands every so often in the folder to force the jpeg files to be updated.
Can anybody help me resolve this file update problem?
