OS Selector problems

So, i installed Acronis OS selector, and it told me to reboot which i did, and followed everything it todl me too. When windows restarted i got a bubble popping up saying "your disk space level is low" so i check and from me installing the OS selector to rebooting, 100gb of space had been used up, but i can't find what used it anywhere. So i check for hidden partitions to see if it had created one but it had not. and now i'm stumped. So would anyone happen to know what it could be? And perhaps how to fix it?

UPDATE: I installed Acronis Disk Director to see if i could sort the problem out in that, And thats reporting that i have 83gb of free space. But windows is still saying i have about 5gb Screenshots as follows:

Problem sorted!!!!!. After over 12 hours straight tryin g to fi it! Finally have!!! For some reason The OS Selector tried to make a partition, but it failed and there was some kind of memory block. So i ran the checkdisk facilities and it seems to have cleared it!!!. I can go get some sleep now!!!

 

Glad it worked out for you!
