File Ho! -- File Management with Resco Explorer 2007
Posted by Don Tolson in "SOFTWARE" @ 08:00 AM
ZIP File Compression/Decompression
The ZIP file compression / decompression utility works the same way as the well known ZIP function now provided as part of the Windows File Explorer. Files are zipped up by selecting the Compression option from the options menu displayed when you tap and hold the file on the PPC.

The .zip files produced by Resco File Explorer are fully compatible with all the usual extractors, etc. and the ones built into Windows XP and Vista. The compressor routines also provide the usual capabilities of adding to existing archives, validating archives, etc.
Unzipping the file is done the same way -- by tapping and holding on a compressed file.
Resco's File Viewer is built into the File Manager module. It provides on-screen reading (no modification) of all files by interpreting / displaying them as text, binary or hex formats. It can also natively display JPEG, GIF, BNP and PNG graphics. The viewer is accessible from the options available when you tap and hold on the file name.

You can even display encrypted files with File Viewer, as the decryption routines are built-in to the application. But you still need to know the password. :-)
More and more, Registry Editors are becoming 'de rigeur' for the advanced user's toolkit, as we find ways to enhance the performance of the WM devices through the registry. As most of you are no doubt aware, changes to the registry need to be done carefully and hopefully with some knowledge of what you are doing, since there is the potential to completely disable the unit – effectively creating an elegant electronic brick. Fortunately, most commercially available registry editors, like the one in Resco Explorer, guide you through the process of changing or adding registry keys and always provide an 'Are you sure?' question before making any permanent changes.
Resco's Registry Editor is directly accessible from an icon on the Today screen Plug In or from a 'My Registry' entry in the device root in the File Manager.

It has the capability to import registry files from other sources, but I would exercise extreme caution with that. New entries can be defined by their data type and the Editor will ensure the new data conforms to the standards (length, etc.) of that type.

What I didn't see was the ability to export or take a backup copy of the registry and put it in non-volatile storage (like a card) -- although it's mentioned in the PR material on the website. Fortunately, most backup programs do this as part of a 'full' backup, but it would be a helpful addition to Resco's product.
