This thread interests me as it is directly relevant to another thread I have started. I need to do a repair OS Reset but free space on C keeps dropping despite cleanups etc. It is normally 5 to 10 GB but has plummeted to only half a GB. I cant use the SD Card as hoped because its file system only allows 4 GB. But I have an external USB HDD with NTFS so may try launching the ISO from that. Is that likely to be OK?
On my 3 Tablets with 32GB drives, I have added 64GB MicroSDXC cards [same as used in smartphones] and installed programs I need on them, frees up some space on C:.
Most SD cards come factory-formatted as FAT32, Windows can't do more than 32GB. One could reformat as NTFS to allow large files [about 4GB] or exFAT which Windows can do. There are other programs or operating systems such as Linux with GPARTED or the free downloadable GPARTED to create a bootable CD to manipulate partitions, I use both depending upon the situation/need.
