Resource Warning by uploading file

[KoppDaniel]

By using the keyword 'Upload File' i get the following warning message:

C:\Program Files\Python 3.7\lib\site-packages\FtpLibrary.py:409: ResourceWarning: unclosed file <io.BufferedReader name='C:\Path\To\My\File'>
outputMsg += thisConn.storbinary("STOR " + remoteFileName, open(localFilePath, "rb"))
ResourceWarning: Enable tracemalloc to get the object allocation traceback

@KoppDaniel please upload log files if possible

@kowalpy Sorry I was not able to upload any log file.

But the issue is on lune 409 of FtpLibrary.py that a file is give to the function storbinary but it is never closed.

outputMsg += thisConn.storbinary("STOR " + remoteFileName_, open(localFilePath, "rb"))

The fix would be the following:

with open(localFilePath, 'rb') as localFile:
outputMsg += thisConn.storbinary("STOR " + remoteFileName_, localFile)
