After collecting a lot of pdf files i decided to organize them but part of the files (U.S. Army Field & Technical Manuals) have a special numbering like this:
- FM 1-10
- FM 1-195
- FM 4-119
- FM 101-15
- TM-E 31-480
- TM 3-376A
- TM 9-421
- TM 9-1901
Initially i number them 1.10, 101.15 but the problem is that caliber don't let me use more than two digits after the period also some of them have two subdivisions like FMI 4-93.41.
Any recommendations are welcome.
