cozofdeath Posted December 27, 2006 Report Share Posted December 27, 2006 I have a file that has no easily identifiable format. In looking at the file header I can mostly tell what it is but I'm not 100% sure because when I add the extension and try to open it, it won't open. It may be corrupt, but my question is...is there any good programs out their that will tell me what format a file is? I don't mean the extension, just the format. Thanks in advance.

jason.b.c Posted December 27, 2006 Report Share Posted December 27, 2006 7-Zip...???Win-Rar maybe..? Quote Link to comment Share on other sites More sharing options...
ɹəuəllıʍ ʇɐb Posted December 27, 2006 Report Share Posted December 27, 2006 There are basically only two file formats: plain-text and non-plain-text. Plain-text files can be opened with Notepad, or about just anything that can display text. All other files are formatted in a way that only the proper program can understand. Looking at the file with some hex viewer can sometimes tell you what it is, but many times you won't know what it is.I usually use FileAlyzer to take a first look at such files.

cozofdeath Posted December 27, 2006 Author Report Share Posted December 27, 2006 The file is split into seven parts. So I figured its a rar file. But after adding part1.rar, part2.rar, etc. and .r01, .r02, etc. to the end of the filename it didn't extract. Then I thought maybe a splitter made the file or its corrupt. I'm still not sure but I haven't been able to get winrar to open it or anything else including file joiners. Quote Link to comment Share on other sites More sharing options...

cozofdeath Posted December 27, 2006 Author Report Share Posted December 27, 2006 I usually use FileAlyzer to take a first look at such files.Thanks. The hex dump made me see some useful things and I now know its a xvid avi codec/format movie. I have compared compressed files to the movie and it seems its not compressed but corrupt because the Riff and Media tabs either don't show, error out, or don't load all the way. Its like the file was split but doesn't include any info on how to put it back together. The first file is the only one with the riff/avi header, the rest just have data.Can you show us a screen shot..?Error when trying to open as a .rarError when trying to join the filesWhat is this file for exactly.? , A Software ( program ) or somethin' else.. Just curious... Its a comedy movie split into 7 files, 100mb each. The first one works but none of the rest can be recognized at all. I can see what size it is, I know its an xvid, avi movie because of the hex dump of the first file of the movie but I can't see the rest. I can't open them in other programs to even join the files together or convert. The 2nd-7 don't play at all they just freeze the movie player. I think I'm just going to delete it.btw thanks guys for the help :D With Gspot and the hex dump I seen the movie was processed somehow with virtualdub. Is it maybe this program that has to put it back together? I don't know much about it and I'm not to much into splitting up files. Quote Link to comment Share on other sites More sharing options...
ɹəuəllıʍ ʇɐb Posted December 27, 2006 Report Share Posted December 27, 2006 You should try to get information from wherever you downloaded these files. There are many file splitters, and naturally they need to be rejoined by the same method as used in the original split. Quote Link to comment Share on other sites More sharing options...
Coreper Posted December 30, 2006 Report Share Posted December 30, 2006 try extracting all files to one folder > which puts all the parts togetherbtw @Pat: i also use FileAlyzer!another thing: this file might also be part of an failed action to make a partitioned package, by a corrupt programmaybe you will get to know more by opening the file in Notepadanother thing: try Google [sounds stupid, but i helped my out a lot of times] Quote Link to comment Share on other sites More sharing options...
cozofdeath Posted December 30, 2006 Author Report Share Posted December 30, 2006 I finally came to the conclusion it was an xvid avi and that it was split or possibly corrupt, but I had no clue what program split it and it was driving me nuts so I deleted it then I kicked my monitor to the ground. Thanks though nice to see your back. btw I didn't really kick it but I wanted to. Quote Link to comment Share on other sites More sharing options...
10west Posted December 30, 2006 Report Share Posted December 30, 2006 There are several sites with explanations of the file extensions, commonly used, which will give you a clue as to the format. the extension, is used by windows, and others after, to identify it to the system, and what actions can be taken, by what, where, how etc. Search the original extension, and if it's common, or even rare, should be able to find out what craetes it, and whta it's for. .iso files for instance, are compacted like a zip, but require a different extraction, for install exe's, setups etc.http://filext.com/detaillist.php?extdetail=ISO <<<type in the ext, and search here Quote Link to comment Share on other sites More sharing options...
