Windows 10: Does File History process, compress, or otherwise distort backed up files?

I am considering using File History to backup some files and folders on my Win 10 computer. I have relentlessly, but unsuccessfully, searched for information on the operation of File History. Can I copy and paste individual files and folders that were backed up on an external drive using File History wherever I want? In other words, does File History process, compress, or otherwise distort the backed up files so as to make them unusable any where else?

Compress files??

It all depends on the contents. Back in the early days of DVD games, they had plenty of space compared to CD's. So they left stuff uncompressed on the DVD itself. Compressing such ISO image would result in very high compression ratio. But these days, even DVD discs are becoming small and game companies are already using data compression to fit more data on the same DVD. And since you cannot compress already compressed data, you're seeing more and more of the 99% compresion ratio moments.

Good examples of such scenarios is when you want to compres uncompressed WAV file and a MP3 file. WAV is not compressed and you can decrease its size significantly. You might gain few kilobytes when trying to compress already compressed MP3. The same is with images. You can compress BMP images rather well but when compressing JPG images, you won't really gain anything as its already compressed.

There are few very specialized algorithms that may gain some more compression out of already compressed data, but the gains are usually very small and usually not worth the extra compression time needed to perform the compression itself. Plus you can only use them to compress very specific data files.

 

File History not backing up any files

Hello Victor

Thank you for the response. I had already checked that thread, but it hasn't helped me:

• The thread deals with Windows 8's implementation of File History, which is somewhat different to that of Windows 10.
• Most of the thread deals with setting up File History (which I have already done, precisely following the recommended steps). The third link in the thread might have been useful since it appears to link to a page that deals with troubleshooting File History
  (as opposed to setting it up), but unfortunately the link is dead.

Any further suggestions would be greatly appreciated.

 

Compress files??

using upx? to compress exe files
but you need to make it executable zip first then do upx
