Disk Sizes and File/Directory Size Differences

-

hi all,

i sure simple 1 have vm have attached 550gb hard drive to, drive in windows explorer 549gb expected. on drive have 2 folders, if select folders , go properties advises folders 596gb.

the administrator account using perform check has access 99% of folders, 1 doesn't 42mb in size. have on 9gb of shadowcopy files , compression turned off on drive , on folders next level down (i didn't want go , check every directory) , believe turned off on every folder.

at moment can't understand how storing more data hard drive can hold. thing can think file attributes on files/folders has corrupt or being counted twice in instances.

i can't embed images due verification, see below examples.

hi,

first recommended run check disk. can show correct size on volume.

i encountered 3 possible causes of issue.

1. check if caused paging file.

2. have programs installed, reserved size log or data file.

3. said, default not have permission access folders. please check if can access "system volume information" folder. 1 of several subfolders of large not calculated because of permission issue.

here thread caused event log – not calculated disk space missing properties of system volume:
