    1111== Task requirements == 
    12 ^(List the necessary requirements that the task must fulfill.)^ 
     12 * Created a special BinData that can contain link to a file and reads only requested parts of it. 
     13 * When the user opens big files for resources containing BinData ask the user if he/she wants to link the file or automatically link the file if it is too large. 
     14  * If the file is smaller than ? MB automatically embed it. 
     15  * If the file is between ? MB and ? MB ask the user if he/she wants to link or embed it. 
     16  * If the file is bigger than ? MB  automatically link it. 
     17 * Create special dialog for user interaction for large files or modify the file dialog if possible. 
     18 * Create BinData that can link every type of URL (optional, hard because there could be no API that can do that). 
     19 * Ask the user if he/she wants to copy the file in special directory that can be transferred with the book. (optional, hard due to relative paths). 
     20  * That will work only with files saved on the file system. 
     21 * Think of working with large resources on the server (optional, that is different task, but if there is time there could be done something). 
    1322 
    1423== Task result == 
    15 ^(List the end product of the task (for example "Source code", "Wiki page", etc.))^ 
     24The result of this task will be source code. 
    1625 
    1726== Implementation idea == 
    18 ^(Provide some rough implementation idea(s).)^ 
     27 * Make the current BinData abstract class that has two extenders: 
     28  * EmbeddedBinData (working as the current one) 
     29  * FileBinData (linking files). 
     30 * Make the FileBinData#getSub method to read from it's file with random access. 
     31  * First it will seek to the wanted position in the file. 
     32  * Then it will return a new BinData containing only the bytes from the passed position with length, the passed one.
