Want Windows to Copy Large Files over Network

Transferring large files from one location to another is unavoidable nowadays when everything is moving towards refinement. The development of network also makes connecting to each device easier. Thus, many users want to Transfer files from PC to PC (including large files) or other devices over network.

"I’d like to transfer some of my videos files, in large size, from my Windows 10 to another computer which is connected my LED TV. The two machines are in the same segment of LAN, and I guess I could transfer them over network cause I don’t have a suitable external storage to transfer them manually. But the network approach is really slow. Is there any way to do it faster? Thanks.”

In fact, there are many reasons for transfter speed slow, or any other problems in the large files copy process. Don't worry about it and I'll show them in details. In addition, you still can try the fastest way to copy large files over network.

Problems Copying Large Files over Network

Two most common problems of Windows 10 large file copy fails or slow transmission speed. In general, there is several reasons most likely account for the phenomena.

  • Bad network connection. This would be the main reason for copying large files over network slow.

  • Complex transfter process. Windows will first copies files to another computer and then deletes the source files, so the bigger the file, the longer the transfer time at a given network speed.

  • File size limitation. You may receive the file is too large for the destination file system error if you transfter large files to FAT or FAT32 partition, which limits file size to 2GB or 4GB. To get rid of it, you could consider converting FAT or FAT32 to NTFS or make these files smaller.

  • File is occupied or corrupted. A damaged file is possibly not recognized by the Windows transfer tool, which results in the entire process hanging and waiting for further instruction.

  • File conflicts. A conflict file appears when multiple versions of files or folders attempt to be copied to a single file or folder.

So what we can do to make the file copy process faster? Simplify the transfter process, be sure the target disk using NTFS file system, or make files smaller. You could consider using file transfter software.
