What cataloging system for PDF articles exists in the portable version for Windows?

Question

Cataloging

Health to all, comrades! Tell me, maybe someone came across a free tool that will allow you to run a kind of catalog shell, into which you can add PDF files, and, most importantly, will allow you to put tags on files. The bottom line is, in the course of my love to keep interesting articles on system administration / engineering / pentesting, I have accumulated a healthy collection of PDF files, the amount of which starts to boil the brain. And most importantly, I understand that an article can be devoted not only to a single topic, it can be "stigmatized" with different tags, which would be further easier for searches "here they already wrote about this thing somewhere, and in passing." For example, an article about protecting a web server can contain both attack methods and protection methods, and these are slightly different approaches. So I'm looking for some kind of portable (important, exactlyportable ) program in order to import a file into it, assign tags to it (and if it is a direct book, then the year of publication, author, etc.) and then store the whole thing on an external drive, such as a portable reference library.

As of 04/08/2020, I found a more or less suitable option, not portable, which is bad, but you can assign tags - Daminion. But still, it's not exactly what I'm looking for.

Answer 1

Feel this. In theory, after installation, you will receive an additional tab on the file properties. But even without this, windows search for the contents of these files

Hmm ... it turns out that since I used Windows, both Yandex and Google have already managed to close the local search engine project. But there are others .

Answer 3

For cataloging by tags of documents, notes, web pages, pictures, only Evernote is suitable, in terms of ease of operation and storage ... But it starts only with the Internet, it is stored on a computer in a specific form, the free limit for passing new data is very small. I tried to use it purely on a computer, without the bells and whistles of the organizer. And when introducing new files without synchronization, so as not to be limited by the monthly limit, he was generally taken down and cannot be registered on a new one due to old overflows. There is a Chinese analogue, in which you can even operate with PDF files, but I couldn’t cope with the free stuff and rushed to try out other organizers and catalog creators, but all of them with their jumps and without the ease of working like with evernote. I even tried to sculpt my directories based on the old Windows Help, but there are too many side effects and all of them must be kept in mind, i.e. stupidly in two clicks it doesn’t work like in damn Ever
