Eight character filenames

Post by astral_cyborg » Mon Nov 29, 2010 10:24 am


I have a small problem with the the result of some files. Their file names are displayed with 8 characters (like DOS names, ending with ~1) instead of their full filenames.
For example a file called "Abcdefghijklm.file" is displayed as "Abcdef~1.file".

Thus, I cannot find them with normal file search (hopefully, if I have the "Match Path" option of Everything enabled, I can find them through their folder names results).

This happens especially on .mp3 files (usually on latest copies from external sources or downloads). I'm not sure if it happens after id3 tags modifications or not. But I remember that occasionally, I've encountered that kind of results with other filetypes, too.

If I copy these files in another partition of my hard disk and then re-copy them to their original place, then their names get fixed and they can be displayed in my Everything search results normally.

Any ideas how to prevent that phenomenon? My OS is Windows 7 x64 and I use my hard disks in RAID-0.

Thank you.

Ok, I've noticed that after renaming the short-named files and restoring their titles again, the search results of Everything are now displayed both with full and short names, on the same path.

After some time passes, the search results get restored and display correctly. Does that have to do with the index of Everything or with Windows (MTF or something)?

Is there any way to restore the search results manually?

Thank you.

I'm going to venture to say that they are in fact either SFN or file names that happen to have a '~' in them.

If you were to drop to a C: prompt & do a:

Code: Select all

... Then if only one filename (on a line) is returned, then it is a SFN.
If more then one filename appears on a line, then it is a LFN that appears as if it were a SFN.

If there is only one filename listed on the line, & it is listed leftmost, then it is a SFN:

Code: Select all

O:\OLD.OTHER\WEBCOW\tmp\FeeKaroke>dir /x blackh*.kar
 Volume in drive O is OTHERNOLD

 Directory of O:\OLD.OTHER\FeeKaroke

12/16/1996  03:46 PM            55,738              BLACKH~1.KAR
               1 File(s)         55,738 bytes
               0 Dir(s)   3,474,591,744 bytes free
If there is only one filename listed on the line, & it is listed rightmost, then it is a LFN.
If there are two filenames listed on the line, then there are both SFN & LFNs for that file:

Code: Select all

C:\TMP>dir ap2* /x
 Volume in drive C is ZAR7C95

 Directory of C:\TMP

Note the file: AP2S~1.SAF. It looks it is SFN but in reality it is only a filename that happens to have a '~' in it.
