Hi,

Actually those are two questions..Sorry for that (again... )
1) When acknex.exe searches for a file - is there a) any possiblity to create a callback function for plugins (e.g. on_search_file) for the case that no file has been found, or b) how does the engine search for the file (so more basically, which instructions are used)?

2) Is it generally allowed (from a license point of view) to write a plugin that encrypts all files and - according to the callback function - decrypts the nessassary files (e.g. with add_buffer)?

Thanks a lot,
regards,
Timo

It is allowed. There is no callback function, but your plugin can use add_buffer. Files are looked for first in the buffers, then in the path and then in the WRS. Some files, for instance media files, are not opened by the engine, so you can't use your plugin for them.
