Is this also reproducible for you with current nppftp version 0.26.9?

I just installed the new version. Is there something changed in the new version that might stop the crashes?

I just can't reproduce the issue with the current version. Main changes in der Versions between 0.26.3 and 0.26.9 are updates of the underlying libs (libssh, openssl, zlib). But that shouldn't affect a plain ftp connection.

Issue seems to be a access violation, see e.g. https://blogs.technet.microsoft.com/askperf/2007/05/29/basic-debugging-of-an-application-crash/

This happens when the FTP server closes the connection after a certain time of inactivity, i.e. what most hosting services do.

It believe it would be sufficient to check if the connection is still alive before uploading files or reading folders, and if it's dead, reconnecting first.

Related to #1, which could avoid the closed connection, but anyhow there shouldn't be a crash if a closed connection is found.
