Help with 8.3 filename

[clock]

so I used Aomei NTFS to FAT32 Converter to convert without losing files
After completion I got problem with file names


For example this is what is look like for nearly 80% of the files

Png became pn0 pn1 ….
And the name cut off
Happens to other types

The non English names became weird and non readable

when try to rename any file from (EXAMP.PN0 ---> EXAMP.PNg) windows recognize the previous name and asks me to add number because there is already file with this name already even though it is not shown as it is

 

 

and after search and ask I found that the names are converted to what called 8.3 filename

my question is it reversible ?

when I try manually change the extension I got windows prompt "are you sure you want to change .... "  I got the original file name so it must stored somehow I don't know

Firstly why did you do this? What kind of machine is this on? What storage is this about?

 

No it's not going to be undoable, and the reason you'll get Windows telling you about duplicates is likely that you have multiple files that start with the same first 8 characters, so when you try to change the extension there's already a faile of the same name, you'd need to change the main name to be able to set the correct extension.

I did this on external hard drive because of mac os nonsense about ntfs

here is the thing when Windows telling you about duplicates it shows the original name as full but after hit ok it get back to 8.3 filename it is weird

look at this pic

this is after yes

For a while the DOS/Windows filesystems would store both the 8.3 filename and LFNs that allowed for "modern" names, seems the aomei tool completely screwed that up...

 

Nowadays you want to be using ExFAT for drives you use with multiple systems.

so there is no hope to fix this just manually rename ?

[Kilrah]

Yep that's most likely the only solution other than restoring from a backup that you should always do before such big operations on important data... never trust the "without loss" tools, always have a fallback if it breaks.

yeah I was lazy to make backup before doing this

thank you
