I have purchased and downloaded some movie clips. They are in the Firefox Downloads folder. I can play them when the clips are downloaded but after about 24 hours, if I right click and look for Open Containing Folder, it is greyed out. I have noted that they are placed in my Temp folder in the C Drive when first downloaded. On one occasion I saved the file from the Temp folder to My Documents and have returned to it and been able to play it. It occurs to me I may have made a basic error when the download starts. I am asked if I would like to play on Windows Media Viewer and there is also the alternative of a Save option. I assumed that all downloaded files would be automatically saved to the Firefox Download file. Should I have selected the Save button instead? There appear to be no security issues because the file size and site details still appear below the file name.
