El siguiente script desarrollado en PowerShell y dependiente del programa externo RAR.exe (WinRAR), sirve para comprimir cada directorio dentro del directorio actual de forma individual, con compresión máxima, y utilizando los tamaños de diccionario especificados. La sección "Variables" dentro del script permite configurar varias cosas, entre ellas: - Los tamaños de diccionario. - Las extensiones de archivo que se deben procesar sin aplicar compresión. - Preservar solamente el archivo RAR generado con el menor tamaño de todos. (eliminar los archivos RAR de mayor tamaño) - Especificar una diferencia de tamaño (tolerancia) arbitraria para eliminar archivos RAR generados (con mayores tamaños de diccionario) de un tamaño de archivo similar. - Enviar los archivos RAR eliminados a la papelera de reciclaje. Es muy útil, por ejemplo, para comprimir de forma automatizada directorios de video juegos para PC y obtener así el mejor resultado entre Tamaño de diccionario / Tamaño de archivo.

Hola. He visto tu entrada y me ha interesado el tema porque yo estaba pensando en hacer algo similar pero con VBA.
Quería hacerte variaspreguntas:
1. Cuando comprimo un archivo o carpeta, creo un rar con WinRar y un 7zup y un zip con 7zip. Luego escojo el que menos ocupa. ¿Se podría añadir esta opción?
2. No busco tanto que me genere un archivo comprimido por cada archivo / carpeta dentro de la carpeta, sino poder elegir si quiero un archivo individual, una carpeta solo, o varios archivos o varias carpetas o varios archivos y carpetas, y esto que lo comprima en una carpeta (que aparezca en el archivo comprimido primero la carpeta), o sueltos (que cuando abra el archivo comprimido se vean ya los archivos y carpetas que contiene). ¿Se podría considerar esta opción?
Si hace falta capturas que complementen mis preguntas, al mediodía las comparto.
Saludos y gracias por el aporte.

Quería hacerte variaspreguntas: Agradezco tus sugerencias, pero este aporte no se debe considerar un proyecto abierto a solicitudes de cambios. Ni siquiera se debe considerar un proyecto. (En GitHub si tengo proyectos, todos ellos abiertos a solicitudes, abajo en mi firma de usuario hay enlace a mi perfil de GitHub.) El script está hecho a medida para cumplir con mis necesidades personales. Simplemente lo comparto en el foro para que le pueda servir a otras personas que puedan encontrarse en situaciones con cierta similtud, para que puedan adaptar el código a sus necesidades, mediante sus conocimientos de programación. Dado el caso siempre puedo considerar implementar alguna sugerencia muy puntual que no implicase realizar muchos cambios al comportamiento del código, y que sirviese para un propósito generalizado, pero no voy a adaptar el código a las necesidades específicas de otras personas para acabar fabricando un nuevo script prácticamente desde cero, por el tiempo que ello conlleva.
creo un rar con WinRar y un 7zup y un zip con 7zip. Luego escojo el que menos ocupa. La eficacia de compresión de 7zip es superior a la de WinRAR, lo que supone que, al utilizar el mismo tamaño de diccionario y una configuración de máxima compresión, 7zip siempre debería obtener mayor tasa de compresión que WinRAR, aunque fuesen solo un par de bytes de diferencia al comprimir formatos de archivos que ya estén muy comprimidos. poder elegir si quiero un archivo individual, una carpeta solo, o varios archivos o varias carpetas o varios archivos y carpetas
El comportamiento de un script puede ser configurado mediante la implementación de parámetros a través de la línea de comandos. Pero este script trabaja con una configuración hardcoded, es decir, con valores definidos directamente dentro del código fuente, en la sección "VARIABLES", por lo que para configurar el comportamiento del script hay que editar dichos valores. Lo que propones implicaría demasiados cambios. Lo siento. El script procesa las carpetas de forma secuencial, todas las carpetas que haya en el directorio actual, sin opción a permitir seleccionar solamente "X" carpetas para la compresión. Ese tipo de personalización sería más óptimo implementarlo en una interfaz gráfica de usuario (GUI), pero no en un script como este. y esto que lo comprima en una carpeta (que aparezca en el archivo comprimido primero la carpeta), o sueltos (que cuando abra el archivo comprimido se vean ya los archivos y carpetas que contiene).
Ese comportamiento lo puedes alterar en el script simplemente borrando o añadiendo el parámetro "-ep1" de RAR.exe: -ep1 Exclude base directory from names El parámetro está añadido por defecto en el script: $arguments = @( " a -u -ams -c- -cfg- -dh -ep1 -htb -idcdn -isnd- -iver -m5 -ma5 -md$($size)m", ...
Si estás trabajando en un script de VBA y necesitas ayuda, para eso está el foro. Siéntete libre de mostrar tus avances y realizar dudas puntuales para seguir avanzado. Aténtamente, Elektro.

me acabas de dar una Idea con este script, un Ransomware que comprima los archivos con contraseña , una contraseña generada especialmente para cada directorio basado en su ruta y algun otro identificador, osea que si cambia de ruta el comprimido , F.
