VKontakte dumper

A script that, using a VK token, can:
* download user´s messages in text format (only personal, only "favourites" or all at once (PM, conversations, groups))
* upload user documents
* load images from dialogs
* download attachments to messages
* check tokens for validity, saving valid ones to a file
* search downloaded messages for text (by regular expressions: emails and numbers). You can also search for any other text by regular expressions, or simply by a complete match of a substring.
* you can save to a file n-th number of messages, next to which there was a word from the previous paragraph

The dumper does not display activity in the profile in any way, i.e. its use does not display anywhere information that the account has access
The script can work in multi-thread (up to hundreds). Information about what is happening is displayed on the command line.

It has an intuitive graphical interface with many settings.


Important: The software works on Windows, starting from version 8.1 and higher!
