Hi, could you implement the feature to remove the nstemp files from Mozilla Thunderbird? If I get it right, these are temporary files Thunderbird creates when compressing the mailbox files. Problem is the bigger the mailbox files get, the longer it takes. For me it usually doesn't work (takes hours). That way numerous nstemp (and nstempX, X being a number) files are being created in the Thunderbird Profile and the size of the folders drastically increases, as Thunderbird basically copies the whole mailbox file to compress it, but leaves them afterwards. Suddenly you end up with a 20 GB Profile instead of 1 GB.
