### Describe the new feature

Thank you for this great app!

i wish you will Support custom Folder and Apps.
I have some Portable Software like 7zip, WACUP, TOR, BleachBit and some more.
Also i use somtimes Portable Apps from PortableApps.com
Way i use Portable Software?
It can be clean up your Device. eays to move software on some device. easy reinstall of backups with apdata.

if it is not posible autoupdate than just and versionscheck.
an Coummunity Database can help to add webside/orginal downloadsource and some optional target.
as soruce can be github websidecrwaler or protableapps.com.
added manual rules by user can help to update in the future automaticly the portable version of webside, the 32 or 64bit and unpacking archivs in the right directory.

example:
- https://www.7-zip.org/a/7z2409-x64.exe (is v24.09 A rule can help to update in future https://www.7-zip.org/a/7z****-x64.exe or https://github.com/ip7z/7zip/releases (webside rule or update from gibthub)
- https://getwacup.com/ (crawl from side)
- https://github.com/thetorproject (update from github)
- https://github.com/bleachbit/bleachbit/releases (32 or 64 chose by users rule)

right now i use UChecker (Portable) to check my Portable software or seperat install folder and update manual.

i hop you understand.
