Hi atilla,
there was a problem with two strings, could you please check my corrections? (I replaced known.met with %s (the file name) in the first word of each translation.)
#: src/CanceledFileList.cpp:81
#: src/KnownFileList.cpp:115
#, c-format
msgid "IO error while reading %s file: %s"
msgstr "%s dosyası okumada IO hatası: %s"
#: src/CanceledFileList.cpp:104
#: src/KnownFileList.cpp:161
#, c-format
msgid "Error while saving %s file: %s"
msgstr "%s dosyası kaydedilirken hata: %s"
