FileZilla Forums

I've upgraded FileZilla Server to 1.0.1 from 0.96.0 on a windows Server 2019 server, then I noticed that upload files are blocked. Thanks a lot for people on this foum helped me to find out it's because I enabled Controlled folder access on target folder! .

The path is "C:\Program Files\FileZilla Server\filezilla-server.exe" for 1.0.1 and "C:\Program Files (x86)\FileZilla Server\filezilla-server.exe" for 0.96.0. I added "C:\Program Files\FileZilla Server\filezilla-server.exe" to the "Allow an app through Controlled folder access" list(whitelist for short), then I can upload files to that folder.

The next day when I tried to upload files, it's blocked by Controlled folder access again, the same error message is logged(425 Error while transfering data: 5). I checked the whitelist and filezilla-server.exe is there. I removed then add it again, and it's working once more. This issue has happened 3 times.

It seems that Controlled folder access will ignore the setting after a day or so, but it didn't happen on 0.96.0.

FileZilla Server doesn't change any system settings. From a technical perspective, there is no fundamental difference between how 1.0.1 and 0.96.0 access files/directories. In particular, there is nothing in the server that would result in a change "after a day or so".

As to why the Controlled Folder Access setting keeps changing, I suppose it's a question you need to ask Microsoft support.

The only fundamental difference between 0.96.x and 1.x is that the former is 32bit and the latter 64bit.
