Limit shadow copy space6/7/2023 In Accessories Right Click on Command Prompt and select Run as administrator. You can check what space is being used and allocated to shadow storage by follow this guide.Ĭlick Start, then click All programs followed by Accessories. Therefore manufactures 320 GB hard drive = 298,000,000,000 bytes.Įxample 320GB manufactures size converted to MS binary scale.Īlso further missing HDD space could be due to the space used by Windows's System Restore. Microsoft, ie windows XP/Vista/7, use the binary, for example 1KB = 1024 bytes ![]() Manufacturers use the SI scale for example 1KB = 1000 bytes To start with your 320GB HDD is actally 298GB the difference in hard drive size is partly due to the different way manufactures and Microsoft report the sizes. Why is it showing used space as being 62.1GB when the total of the folders/files is less than 20GB? I want to split the C partition into two partitions and I felt that 50GB would have been fine for the Operating System and Programmes and I would have used the balance for data storage but it looks like a lot of space is being wasted somehow on C drive.I would be grateful for some advice on this. The restore partition is separate from disc C partition so that has nothing to do with it. I included all files and folders shown against disc C to calculate the total size of folders. When doing a "properties" check on disc C, it shows used space as being 62.1GB and free space as being 225GB. I then totalled up all folders on disc C, which comes to 19.7GB. When a file is modified, the storage space used by shadow copies. Similarly, when the maximum shadow copy storage amount is reached, one or more of the oldest shadow copies are deleted to make sufficient storage space for the next shadow copy. ![]() I changed "folder options" to show hidden files and to show all extensions. When you reach this limit, the next shadow copy that you take replaces the oldest shadow copy. ![]() I did a disc cleanup and defragmented the disk. I have uninstalled some of the preinstalled applications to free up space as I have no use for them. Try to set 'No limit' and check the current usage for two weeks (depending on how many times a day you schedule shadows). Some systems required 10, some upto 50 of disk space for me. It came with Vista (on a 320GB disc) but I upgraded to Windows 7 using the Sony upgrade kit. Id expect about 20 of used space, but this is very dependent on a resource usage pattern.
