For example it can be some FireWall/Antivirus/Internet security application that controls network downloading processes and writing data to disks. Such problems may occur because of conflicts between IDM and other applications. The corruption of data may happen because of the following reasons:ġ. When the data does not match in several connections, IDM starts downloading the file from a scratch using one connection.
When the data does not match, IDM re-downloads the non-matching file part from the beginning. When IDM resumes a download, it falls back on several bytes and compares the beginning on new data with the end of old data downloaded earlier. When IDM downloads a file using several connections, It requests several bytes more for every file part to match the adjacent file part data which was downloaded by another connection.
