Strictly cache-related information:	Local file system cache?	Filenames same as/similar to original filenames for easy finding or, at least, do they have the same extension?	Stores binary files w/o modification?	Cache relocatable?
Desktop PC browsers: IE7 RC1	+ (all files are stored in the subdirectories of c :\Documents and Settings\ USERNAME Local Settings\ Temporary Internet Files\ Content.IE5\)	+: original filenames are pretty easy to guess / search for (unlike with the two other browsers): they start with the original filename and continue with a possible index; they also have the original extension	+	n/a
Opera 9.02	+ (all files are stored in c :\Documents and Settings\ USERNAME \Application Data\ Opera\ Opera\ profile\ cache4\)	0: they have a machine-generated numeric filename but at least their extension is the original; original filenames stored in dcache4.url	+	n/a
Firefox 1.5.0.7	+ (all files are stored in c :\Documents and Settings\ USERNAME \Local Settings\ Application Data\ Mozilla\ Firefox\ Profiles\ SOMENAME. default\ Cache\)	-: the worst: they have a machine-generated filename and the extensions are also dropped (unlike with Opera (Mobile)). That is, it takes the most work to find / identify a given file with Mozilla.	+	n/a
PPC browsers: IEM (WM5 AKU2.3)	+	Same as with the desktop IE	+	+ ; see the Relocate the PIE / NetFront Cache article (alternate links in the Recommended Links section or above)
Opera 8.6	+	Same as with the desktop Opera	+	+; see this
NF 3.3 commercial final	+	Numeric filenames	- (all files have the HTTP response headers in them)	+; see the Relocate the PIE / NetFront Cache article (alternate links in the Recommended Links section)
Minimo (09/24/2006 nightly build)	+ (exactly as with the desktop Firefox case; the cache will be stored in the \Cache directory of the chosen drive)	Same as with the desktop Mozilla	+	+ in the Advanced dialog, in the drive selector drop-down list
Thunderhawk 2.10303	-	n/a (There is no cache)	n/a (There is no cache)	n/a (no cache)
