Sonic Record Now Version 6.5

Question

XP Pro Sp3

 

I have old Adobe PDF files that I am trying to burn to disk for protection. The documents are one size but when I add them to the CD record program they show double the size. Example this document was 323KB in size but when placed in the recorder program it takes up 668 KB's

 

This is the data from the file 323KB 8/2004 Application: PScriptd5.dll Version 5.2 PDF Version 1.3 PDF Producer: Acrobat Distiller 5.0 (windows) I have Adobe Reader 9.3 to read it.

 

I am using Sonic Record Now version 6.5 as my record software. It came with the Dell Dimension computer in 2004 I know it is old. Grin.

 

I did multiple scans on it and it shows up clean. Any ideas?

 

Thanks

I think I found the answer to my question. Sharing it here in case anyone else comes across this.

 

"Alternate streams [ADS's] are not listed in Windows Explorer, and their size is not included in the file's size. It sounds like my RecordNow CD software *is* counting the size of alternate data stream(s) associated with the file".

 

Here is a little reading on it. Scroll down to ADS Alternate Data Streams

Thanks Cel01. We don't hear much about ADS here, although they have caused a couple of issues over time.

 

What O.S. were your old files created in?

 

Will you now save the alternate streams on your archive discs, or remove the extra stream?

I don't know what OS since they were created so long ago by someone else.

 

A friend suggested AlternateStreamView a viewer editing program to look at the data.

 

I may install it just to see what it is about but getting me near a delete key is dangerous. I am a novice computer user and get scared easily. Grin

 

Learning something new each day. That is what I like about using computers.

Your caution is understood!! These things can come and bite you quite hard when you least expect it :lol:

 

To learn something new, may I suggest that you first save some files on disc along with their alternate streams, then copy them off the disc again to somewhere else just to be sure you've backed them up in a way that takes the alternate stream too.

 

Then when you have a full copy safe on disc, try stripping the ADS off one or two of the copies and see if they still behave the same as the original PDFs when viewed in Adobe Reader. If they still behave the same, then the ADS is redundant and can be left out of the backups.

 

I don't know the 'official' way to strip off the ADS. I do it by copying the file to a FAT32 hard drive or a USB pendrive, and that works happily. It doesn't change the original file.

 

If you still don't feel comfortable removing the ADS, then just save the original forked files to disc. The media don't cost that much and you have secure backups. :)

 

[i'd be interested to know if stripping the ADS off changes the behavior of the PDFs.]

 

Regards,

Brendon
