Compression sampler

[davidsplash]

it would be great if you had a compression sampler so can i choose what format is best for a certain file type.

Would that be a feature that would estimate and display results for diff. compression formats for the selected file(s)?

Or would it have to compress the file(s) into multiple formats (in a temp folder) and report back the results to the user?

I’m currious how this might work. Not to critisize.

Here you go… (left to right - best to worst)

Text (.txt) 7z, cab, bz2, gzip, zip, bh

Word (.doc) cab, bz2, 7z, gzip, zip, bh

Music (.wav) 7z, bz2, cab, gzip, bh, zip

Graphic (.jpg) cab, bh, zip, gzip, bzip2, 7z

Graphic (.bmp) 7z, cab, bzip2, zip, bh, gzip

Acrobat (.pdf) 7z, cab, zip, bh, gzip, bzip2

In the previous compression tool I worked with, comprexx, available at http://www.comprexx.com, such a tool was added …

Thanks but I prefer PA to tell me for my selection i.e the file or files or the folder or the folders i have selected for compression. I insist a tool to estimate the output size for various compression formats.

Well current tools available, such as the “sampler” referred to by Claude, do not work this way and cannot provide this information.

Output size is very dependant on input data (not just filetypes) so if you can find something that can do this for multiple compression formats - with any accuracy - I would be very surprised.

How wrong could the estimate be before you would consider it a “bug”? :p

PA could suggest the best archiving option, basing on the file extension…

…but that wouln’t be 100% right, anyway…

dunno…

Exactly, think of ‘.psf’ as a good example. I expect only PA would “know” what this was.
Or, more common, what about ‘.doc’ which could be different wp files or simple ascii text.
