unknown data type?

[klx300r]

just transferred over a bunch of pics to my A4000 but when I try to view them I get 'unknown data type'?? how the heck do I change the data type again from the icon info :confused: btw, using OS3.9, BB1&2

update: it appears this happens with other jps and lha files only when transferred from either OS4.1/Win7 machine to my A4000 via DropBox

You try to use the Warpt Datatypes?

yup installed it a while back..maybe will try re-installing

@ Oldsmobile_Mike

yup lots and lots of jpg files

bump:hammer:

Check with md5sum or similar that the files have not been corrupted during the transfer?

aha that does seem to be the case here and it seems it happens when  transferring files from either OS4.1 or Win7 via DropBox to my Amiga  4000
this is very strange for the file to loose all its  attributes as I've transferred a ton of other Amiga files over with no  such issues???

Does this also happen if you first put the JPEG codestreams into an .lha, then upload the .lha to dropbox, and download the .lha, then extract?

DropBox might want to recompress pictures in some other format, or a JPEG mode that is not supported by the Amiga datatype (such as AC-coded JPEGs).

unfortunately yes even lha files show up with no attributes? I've also tried transferring lha files with no jpg in it and same thing :confused:

@ nyteschayde

yes that's probably whats going on as I recall transferring files over to my A4000 without this problem so big question is how do I go about restoring ' the datatype engine of OS3.9 with BB1&2' :confused:

What's your version of datatypes.library?

Have you opened the files in a program that doesn't use datatypes to confirm that that's the issue?

datatypes.library is v44.47 and I've tried to open jpg files and lha files in WB, using viewers etc with no luck...I just tried transferring a demo over ot my A4000 from my X1000 and on the X1000 side I can unarc the lha no problem but once transferred over unarc doesn't recognize the file at all and same goes for any jpg file sent over..now to check if I download a file from my A4000 and transfer it over to me X1000 to see if same problem happens....................

ok so just transferred working jpf file from my Amiga4000 over to my X1000 via DropBox (or as seen on my miggies as AmiBox and same problem....once file transferred over to my X1000 and I try to open it I get "unknown datatype' from multi-view and pic viewers won't open the file either

Sorry, but this is still not as clear as it could. Could you please try the following (step by step):
a) Take the original JPEG. Determine its file size (probably on windows or any other system where you have direct access to the file). Post the file size here.
b) Take this original JPEG, and provide it here (if possible)
c) Transfer the file to dropbox
d) download from dropbox with the Amiga
e) Determine its file size (in bytes!) with the "List" command. Post this result here.
f) Take this JPEG, also provide it here (if possible).

I can then have a look at the internal structure of the JPEG and see whether dropbox modified (potentially) its inner structure.

ok Thomas, I'm positive that the issue is in fact DropBox manipulating the files & now waiting for AmiCloud to get back up with folder support as I never had such a problem like this using AmiCloud on my OS4.1/ OS3.9 & Win 7 machines.

anyhow as per your request:
a- original jpg size on Win 7 machine- 1.05 MB
b- please reply to my PM and will send you jpf file in question
c- done
d- done (A4000, OS3.9)
e- list shows 1106027 ----rwed
f- see b

Do you have a third computer that can confirm that the files are uncorrupted on Dropbox?

yes and actaully a 4th and 5th as well but always same issue

@ kolla

yes very strange indeed as it seems that any good file that is transferred via dropbox from win7 to amiga or vice versa gets corrupted???

I've never had this problem using AmiCloud but right now it's not working as they are implementing folder support
