Archiving files, compressed or raw

post #1 of 7
Thread Starter 
Does win7 save any kind of hash info when a file is created, so at a later date if you open or copy the file it will tell you if the file is still intact?

If not, then should programs like Winrar be always used for archival purposes since they do have hash verification each time you encode/extract from the archive?

So are compressed files even more secure than raw files?

not really more secure, just smaller
1m of text can be compressed down to 100k or less
if you want secure, compress with password encryption

I don't mean by preventing theft, I meant by using CRC and other methods to warn you if a file is damaged. A bmp file will not tell you if there is one pixel wrong.

all good archive software has test features
most can show the crc info on archived files
