I have the free version of Comodo firewall version 12.2.2.8012 and Windows 10 21H2. I’ve tried different download managers like Free Download Manager, Jdownloader and the default download manager inside firefox, but I had the same result. All these softwares when downloads start, in addition to the original file that has temporarily the dimension of 0kb, they create an additional file named exactly like the original, but with the addition of the .part extension (like video.mp4.part). When the downloading process ends, the software tries to rename the file with the .part extension to the original file name (for example from video.mp4.part to video.mp4). If the software is run inside the container, this renaming process takes a very very long time to be completed depending on the file dimension, while it takes seconds if the software is run normally, outside the container. The partition I use for downloads is selected in “Do not virtualize access to specified files/folder” and I’ve also disabled windows defender and windows firewall, hips and virusscope, but with no luck. So I was wondering if this is just how the container works or if there’s an option I could select to speed up this renaming process.
I use the firefox extension with free download manager, so after I click on a link, the software starts already in the container. Sometimes with firefox I right-click on a link and select “Save link as” to download using the download manager inside firefox. I don’t use an extension for Jdownloader, I just copy a link and paste it into the program.
I’ve seen this with Comodo’s container too, and from my experience it’s basically how the virtualization layer works. When the download finishes, that rename is actually treated like a full file operation inside the container, so big files take forever compared to normal mode. I never found a setting that truly fixes it.
What worked for me was downloading outside the container and only opening the files in the container if I didn’t trust them. Another option is excluding the whole download process from containment instead of just the folder.
Unrelated, but when dealing with large video files, tools and workflows like those around https://www.movavi.com/ made me more aware of how slow file operations can get on big media files. It’s a good example of how file size alone can change everything.
Although I’ve never had such issues with Firefox, I did try Free Download Manager and it also worked fine. The issue you are having is that for whatever reason Free Download Manager is being Contained, which it should not be.
What I want you to do is:
1). Open the Comodo GUI
2). Click settings
3). Click containment
4). Click AutoConatiment
5). in the list of stuff that opens on the right look for free download manager- If you see it there it may have a BLOCK designation under action. Edit this to IGNORE, hit OK and exit
6). Try a download with it and let use know.
