Where on Windows hard drive does Firefox temporarily store PDF files that I open from websites when I have Adobe Reader configured as the default PDF reader?
Where is Firefox storing these files and how can I be sure that they are being deleted regularly?
Files that you choose to open with an external program are saved in your temporary folder. To open it, click the Windows logo orb on the taskbar, type '''%TEMP%''' in the search box, then press Enter.<br>
You can clean out temporary files in Windows using the Disk Cleanup utility. The program can also be scheduled to perform cleaning tasks automatically without prompting.
If it is the same file name that I keep opening up over and over, it appends an incremental number to the end of the file name.
That shouldn't be happening. If you try to download a file that's already in your temporary folder, it should simply open instead of being downloaded again.<br>
I don't know what could be causing it though. First, try upgrading to the latest version of Firefox. If nothing else, your system will no longer be vulnerable to the security holes in the version you're using.
