I may have found a bug. In my decrypted folder there are some (<1%) files I cannot open with any Windows programm. Neither the apps associated with the file type (mostly pdf and csv) nor _any_ other programm. All software reports some kind of "wrong parameter" error upon opening the file.
The encrypted file can be opened using e.g. Notepad++. But of course, except some XML, the contents cannot be read.
All of the original documents have been downloaded from the internet. At that time they could be opened (directly from the browser). They cannot be opened once saved.
I am using BC 2.34.995 with Windows 7. Files are synched using Google Drive.
Do you have any advice?
