Here is the explanation.
First of all i rooted Android 4.3 and then install Rom Manager Program from Goggle Store to backup my all info. Room Manager did not work normaly and i tought that it was due to KNOX. Then i install Philz Touch Coustom Rom and remove KNOX. Then i tried to backup my all sistem via Philz Touch Coustom ROM and it worked. Everything was normal. When i run the Room Manager i could not find backup file to restore. I checked the internal SD Card storage capacity and i saw that it was about 3 GB less. It means Backup file saved to internal Sd Card but i could not find by Room Manager. I decide to find this backup file using ES File manager and the others. I could not find Backup Folder or any Backup file. I tried to one more time have backup via Philz Touch Coustom Rom and this time choosed backup to external SdCard. It worked normaly and and after booting android i found the file using ES File manager and the others but not Room Manager. Then i decided to copy this folder to internal Sd Card to check will i see the same folder in internal SD Card. I relized that i have not enought capacity in internal sd card after backup which i could not find folder but storege size 3 GB less. Any how i tried to copy but after coping 1 GB capacity was full and could not copy all files. It was interesting that when i deleted the copied file about 1 GB, storage capasity of internal SD Card did not change. It was full.
How can i solve the problem? Internal SD Card full but i can not see saved backed file and after deleting file capacity do not change.
