Bittorrent Unfinished Download Format | BitComet | Misc Files |
The BC file extension stands for BitComet Partially Downloaded File, which is used as an incompletely downloaded file.BC files are created while a download is in progress and can be opened only by a BitComet client. This type of file enables pauses and resumes during downloads and hence allows the user to continue file transfers from where the download was interrupted previously.
Once a download is completed, the temporal presence of the BC file ceases to exist and its input is redirected to the subsequent related file like .MKV, .MP4, .AVI, .MP3, etc., depending on the type of application associated with it. Similar file extensions include .IDM, .APK, AACNECT, .SIT, etc.
Advanced Information:
The 'BC' files carry all partial downloads so far and are crucial for handling file recovery in case of network failure, system crash or power outage. These files are usually located within the default download folder of BitComet, but since users are allowed to set new download folders, it is important to check both of them. In most cases, BitComet will automatically take care of these files and delete them once the download is completed. It can also open corrupted files and resume downloads that were interrupted by unexpected errors or system crashes.
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BC) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .BC extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .BC file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .BC extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .BC extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BC file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BC file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .BC file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BC file) will be extended to the maximum.
It is also good to check
- if the .BC file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
