Linux Mint 17, migrated from Win7: Verify that you have enough disk space, and that you have write privileges to the file system, then try again.
I get this error message (The messages could not be filtered to folder 'Generic Folder' because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.) popping up on many, though not all of my incoming filters. I recently migrated from a Windows 7 installation to a Linux Mint 17 system.

have you just left Thunderbird to do it's thing for a day or so. I am guessing you have a large mail collection and that it is being reindexed (hence the locked folders)
I take it the "generic folder" represents a valid pathname in Linux? No backslashes or drive letters?
My Thunderbird stores under
~/.thunderbird/
in LMDE.
Having said that, +1 to what Matt said.

I did give it time to run through everything when I initially migrated, and it frequently will sit open for 3 to 4 hours while I'm working on other projects. The 'Generic Folder' represents sorting folders in my main mail account in Thunderbird. For example, my mail which is listed to filter into my 'Amazon' folder is sorted there with no problem, while any mail designated to be filtered into my 'Games' folder prompts the above error massage.
