![]() ![]() For example, when you visit How-To Geek, your browser downloads the How-To Geek logo that we display at the top of the page. RELATED: Why Is My Browser Storing So Much Private Data?Ĭache files are bits of web pages-images, scripts, stylesheets, HTML files, and more-that your browser holds onto. This is because CCleaner is set up to delete your browser’s cache files by default. However, this would actually slow your computer down in real use. You could use CCleaner constantly, running it every day with the default settings. 'data stream directly readfile C:\file.txt:Zone.Deleting Cache Files will Slow Down Your Browsing, and They’ll Just Come Back Later 'This could also be done by ready the Zone.Identifier alternate 'returns the Zone Identifier of a file, using IZoneIdentifier Public Function GetFileSecurityZone(sFile As String) As URLZONE You can access that stream manually via VB's Open syntax, but it's easier, for this purpose at least, to use Window's built in handling: This is how Windows knows if a file is from the internet. For instance, all major web browsers add this to all downloads: C:\download\file.docxm:Zone.Identifier, a data block containing a value indicating what security zone the file belongs to. These are hidden data blocks attached to a file that don't count towards it's size, so you don't even know if they're there without special utitilities. This project does use the documented COM interfaces for this rather than manually reading/writing the alternate data stream, so if Windows ever does support this on other file systems, there's still a good chance it works. As far as I know, this is only applicable to NTFS file systems. Source requires twinBASIC Beta 239 or newer to open/build. ![]() Version 1.2: Minor bug fixes: Tabstop order incorrect in one spot, and zone deletes/changes couldn't be applied to Untrusted-zone files. ![]() New features to control what files to apply it to and whether to change the zone instead of remove entirely have been added, and it's been updated to use tbShellLib instead of oleexp and to support compiling for 圆4 (not much work here, just had to change 3 Longs to LongPtr). Code Snippet: Get/set/del file zone identifier (Run file from internet? source) This is based on an import of the VB6 version originally posted as a years-later update to an original demo for reading/writing them here: The attribute can't be removed from read-only file, so there's an option for how to handle this: (1) Skip read only files, (2) Clear the read only attribute, remove the zone identifier, and put the read only attribute back, or (3) Clear the read only attribute and leave it that way after removing the zone identifier. ZoneStripper doesn't need admin permissions, and can remove it from any file you have read/write permission for. Ironically, this requires no special permissions. ZoneStripper will recursively (or single level) go through a folder and completely remove the zone identifier from all files, making them just like any other file that came from your own computer rather than the internet. It's easy enough to do this manually for a single file through Explorer (however, this only changes, not removes, the zone identifier), but it might get tedious if you have a lot of files. With Microsoft taking away the option to click through warnings about macro enabled documents and load them anyway, it's becoming more important to 'unblock' these documents, among various other reasons you'd want to do this for other files.
