On his first point, redhawk is partially correct ? cookies do not ?store? the creation date. However, a cookie is a file and, as such, it does have a creation date. While not visible or displayed in CCleaner, you can easily do what you want. I will use Windows 7 as an example, and I will leave it to you to tailor this procedure for Windows XP:
Go to START, RUN, and enter ?C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Cookies\Low? in the RUN box (without the quotes), and ENTER.
When the window opens, RIGHT CLICK on the column header bar, and add the ?DATE CREATED? column.
Then, SORT by DATE CREATED.
On his second point, redhawk may not see any value in sorting by DATE CREATED. You, and others, may see beyond this and use this information for some purpose that redhawk has not yet realized.
Bill, suggestions are what they are. That other users may not see the value should not be an obstacle. Ultimately, the implementation is considered by the developers. There is always a balance between the feature requested (value), the resources (people and cost) required, and the schedule. Only the Piriform management can decide this, and not other users and moderators, although their feedback and comments are equally considered, as are all users feedback and comments.
