I have been dealing with this issue since early 2018 (March-ish). I've been able to duplicate this issue on multiple computers on different networks.
When I resume syncing in Creative Cloud (CC), Windows Explorer (WE) becomes extremely sluggish and slow to respond. Navigating through windows is slow and daunting while sync is going. WE goes through this process of loading folder contents every time I try to navigate to another folder. The quick access bar on the left doesn't even load properly. Icons in folders (even folder icons themselves) do not display correctly. They are just invisible spaces where the icons should be but nothing is there. I have to stop file syncing, quite CC, and restart WE in order for it to be possible to navigate through folders again. I have been forced to let file sync go over night and disable it during the day when I'm trying to work. As you can imagine this is not efficient and I believe the program should not have these issues as working while CC sync is active was not an issue before. I have waited this long to report the issue because I'm fed up with the problem and have been waiting patiently for a solution to come up but none has surfaced that I could find.
Currently I have a Windows 10 custom built system and I have a company laptop (Windows 10). Both are on the same home network and I have both set syncing to creative cloud. I do my work on my custom PC.Once work has been finalized and synced through creative cloud, I upload my work files to my work server via my company laptop. I have Gigabyte internet. I really don't think it's my network because I had the same issue in my office building when syncing from a company desktop to CC and to my desktop at home. Nobody else I know uses CC the way I do so I don't know others with the same issue. All I know is that it was working before early 2018 with basically the same set up.
Please let me know if you need any further information.
I am, and have been having the same issue for quite some time. Was the problem ever resolved? In addition, i find the overlays on my desktop icons are continually changing when running CC sync on Windows 10. I basically have to shut down sync for my PC to operate properly.
I personally have not had this problem with either Win 7 or 10.
But I don't have a lot of files (actually none at the present) synced up with the CC system. I did have Hundreds of images synced with the LR Web system and have never had a slow File Explorer.
Could be the AV program you are using, scanning each and every file on your systems that is synced up with the Adobe CC system.
Two years later and I'm having this problem too... It started a month ago, talked to Adobe about it but they couldn't tell me why this is happening. It's very frustrating. I thought it was because Creative Cloud was upgraded but you also had this problem in 2018. Have you found any solution?
I have the exact same problem now. Any update on yours?
I also have the exact same problem.
The best solution that I found was to stop using Creative Cloud sync. I feel cheated by Adobe, they seem to not care about their cloud services.
Same here. The only workaround is for me to stop syncing while I am working. The moment I resume the sync, windows explorer becomes super slow or sometimes unresponsive. If you have a fix for this in the future, please let me know.
Same here.... I have the same problem.... very frustrating... I thought it is because of Windows 10 but its not... My Adobe CC slows my Windows Explorer
