Temporary files showing 0 bytes even though uch files are present in phone.

Understanding what is going on may require an understanding of how file organization on a storage unit works. I'm not sure if this applicable to what you are seeing. But 0-byte files take up more than 0 bytes of storage space. There are two sizes associated
with a file. One is the number of bytes of content that are stored within a file. A file is broken into segments of uniform size (often called a cluster). Even if a file has 0 bytes in it by simply existing it can consume a cluster. When you delete 0 byte
files the clusters are freed and the file allocation table entry for the file is deleted.

 

WindowsApps folder says permissions are corrupted and need to be deleted, is this normal or critical?

According to your description, I suggest you try the following steps:

1. Navigate to the location C:\Program Files.
   
2. Right-click on the WindowsApps folder, and select Properties.
   
3. Turn to Security tab and click on Advanced.
   
4. Click on Change and then type Users in Enter the object name to select area.
   
5. Click on OK, then click Apply > OK. You can also add the TrustedInstaller to the users list and check if it takes effect.
   

However, you might be still not able to access the files. The workaround is to go inside the C:\Program Files\WindowsApps\, and repeat the same way with the Microsoft.WindowsStore* folders.

 

NTFS problem: 0 byte file but "Size On Disk: 3.98 GB"

By using a Python script, I managed to mistakenly create a 4GB file on an NTFS USB drive with a colon in the filename. The resulting file name was all of the text up until the colon, but the file is listed as being 0 bytes. BUT when I check the file properties
it says "Size On Disk: 3.98 GB (4,282,056,704 bytes)". When I used a file recovery program such as Recuva and MiniTool Power Data Recovery, all 4GB seem to copy to another drive, but it still shows that it's 0 bytes (Size On Disk 3.98 GB).

Any advice as to what I could try next to fix this issue?

The file cannot be replaced easily so I'd like to get it back.

I'm not averse to low level disk editing if it comes to that.

Thanks in advance!
